Entering ssh dev1 is equivalent to ssh -p 2222 deploy@dev1.mydomain.com. Similarly, scp sample.file dev1:mytempfolder/ is equivalent to scp -P 2222 sample.file deploy@dev1.mydomain.com:mytempfolder/. Combining a .ssh/config file with ssh public key authentication, you will be able to login and/or copy files to and from remote servers with ease.

Introduction
Utility scp is a part of SSH suit allows files to be copied between machines. It is an updated version of an older utility named rcp, which is a part of rsh package initially developed by Sun, which in turn was based on BSD source code from the Regents of the University of California.
It works the same, except that information it transfers (including the password used to log in) is encrypted. Also, if you have set up passwordless certificate. Like in rcp you also can use older method based on .shosts file to allow you to SSH between machines without using a password. There is a wrapper for scp which allows passwords via Expect ( NetSCPExpect - search.cpan.org )
This is a command line utility. GUI SCP clients are rare, as implementing it requires additional functionality (directory listing of the remote host at least). The most popular is WinSCP which actually defaults to the SFTP protocol. Even when operating in SCP mode, clients like WinSCP are typically not pure SCP clients, as they must use other means to implement the additional functionality (like the ls command).
The general form of the command is similar to cp command:
where source-specification indicates which file or directory is to be copied, and destination-specification indicates where the copied material is to be placed. Like in cp option -p Preserves modification times, access times, and modes from the original file.
Either the source or the destination may be on the remote machine; i.e., you may copy files or directories into any account on the remote system OR copy them from the account on the remote system into the account you are logged into.
Example:
To copy a directory, use the -r (recursive) option. Example:The format for the remote specification (source or destination) is:
where filename is the name (path) of the file or directory relative to the home directory of particular user on the remote system. For local file in the current directory you can use just filename.
Just like the cp command, scp will overwrite an existing destination file. In addition, if the destination is an existing directory, the copied material will be placed into this directory.
Does scp create the target folder if it does not exist
The short answer is no. But scp is part of ssh you can combine it with ssh command to solve the problem. There are several ways to sove this problem
- You can achieve the goal using ssh + scp (instead of rsync):
- Create directory if it is missing:
- Copy the file to it:
You can do the same from the other end:
- You can use tar with ssh instead of scp. See SSH Usage in Pipes
- If you need to copy a subtree you can use -r switch.
- If rsync is installed on the server you can use it qith the folloqwing options rsync -Pravdtze ssh. Which in combination produces my preferred rsync behavior.
- You can also use rdist.
See alsoDoes scp create the target folder if it does not exist
Examples
- While logged into user on server, copy file 'letter' into file 'application' in remote account abc on sdcc3:
- While logged into abc on sdcc3, copy file 'foo' from remote account user on server into filename 'bar' in abc:
- While logged into account user on server, copy file 'garfield' from subdirectory 'comix' into filename 'fatcat' in subdirectory 'stuff' in remote account abc on sdcc3:
- While logged into account abc on sdcc3, copy file 'garfield' from subdirectory 'comix' of account user on server into subdirectory 'stuff' with the same name 'garfield':
- While logged into account abc on sdcc3 , copy subdirectory 'Section' into a new subdirectory called 'Section' in existing subdirectory 'Chapter' in account user on server:
- From account abc on sdcc3, copy entire account to ir123 on iacs5. This needs to be done from the parent directory of the account to be moved.
Maybe not everyone knows that using the parameter “-l” you can limit the use of bandwidth command scp.
In this example fetch all files from the directory zutaniddu and I copy them locally using only 10 Kbs
Place in .bashrc and invoke like this: “mecp /path/to/file”, and it will copy the specified file(s) back to the desktop of the host you’re ssh’ing in from. To easily upload a file from the host you’re ssh’ing in from use this:
scp file from hostb to hostc while logged into hostaWhile at the command line of of hosta, scp a file from remote hostb to remote hostc. This saves the step of logging into hostb and then issuing the scp command to hostc.

SCP (Secure CoPy) and SSH in general can be used in batch mode without asking for passwords. That is very convenient for scripts.
Procedure for creating private/public key pair
1. In this instructions, the user name is the same in both machines. Instructions for different user names could differ from these (but see note below!)
2. The user keys will be stored in ~/.ssh in both machines.
3. At the client, run 'ssh-keygen -t dsa' to generate a key pair. Accept default options by pressing return. Specially, do not enter any passphrase. (Option -d seems to be an alias of -t dsa in some platforms).
4. Change the permissions of the generated .pub file to 600 by commandingchmod 600 id_dsa.pub
5. Copy the public key to the server with scp id_dsa.pub 'user@server:~/.ssh/authorized_keys'. (Caution: if that destination file already exists on the server, copy first to a different file foo and then append the contents with cat foo >> authorized_keys executed on the server).
6. Done! Verify that now you can connect directly from the client with sshuser@server without being prompted for a password.
7. If it doesn't work, verify that in the server your home directory, the .ssh subdirectory, and the authorized_keys file do not have writing permissions to others. If they do, they won't be considered to grant access. You can correct this with something like:
8. If it still doesn't work, try changing the authorized_keys file name to authorized_keys2, or ask your system administrator what file name is ssh actually using.
9. If it worked, you can now run SCP in batch mode with the -B option, as inscp -B foofile 'user@server:~/foodir/'.
Notes
The name of the server must have been registered in the known_hosts. This can be done with a regular (with password) ssh connection, and accepting the host as known. Then, the host name should be the same as the one accepted! If you used user@server first, do not use user@server.domain.tk later on!
SSH protocol 2 is assumed in this procedure (it uses dsa keys). If your ssh configuration files (at /etc/ssh/) do not establish this as a default, you may have to force it with the -2 option of the ssh and scp. Moreover, if the default public key is not configured to be 'id_dsa.pub' you can specify what key to use for identification with the -i option.
The same procedure worked fine when the username was different in both machines. I simply copied userA's public key at the end of userB's authorized_keys file, then I could login from my client as userA with ssh userB@server.

[Aug 20, 2019] How to exclude file when using scp command recursively
Aug 12, 2019 | www.cyberciti.biz
I need to copy all the *.c files from local laptop named hostA to hostB including all directories. I am using the following scp command but do not know how to exclude specific files (such as *.out): $ scp -r ~/projects/ user@hostB:/home/delta/projects/ How do I tell scp command to exclude particular file or directory at the Linux/Unix command line? One can use scp command to securely copy files between hosts on a network. It uses ssh for data transfer and authentication purpose. Typical scp command syntax is as follows: scp file1 user@host:/path/to/dest/ scp -r /path/to/source/ user@host:/path/to/dest/ scp [options] /dir/to/source/ user@host:/dir/to/dest/
I don't think so you can filter or exclude files when using scp command. However, there is a great workaround to exclude files and copy it securely using ssh. This page explains how to filter or excludes files when using scp to copy a directory recursively.
How to use rsync command to exclude filesThe syntax is:
rsync -av -e ssh --exclude='*.out' /path/to/source/ user@hostB:/path/to/dest/
Where,
- -a : Recurse into directories i.e. copy all files and subdirectories. Also, turn on archive mode and all other options (-rlptgoD)
- -v : Verbose output
- -e ssh : Use ssh for remote shell so everything gets encrypted
- --exclude='*.out' : exclude files matching PATTERN e.g. *.out or *.c and so on.
In this example copy all file recursively from ~/virt/ directory but exclude all *.new files:$ rsync -av -e ssh --exclude='*.new' ~/virt/ root@centos7:/tmp

How to scp a folder from remote to local? [closed] Ask Question up vote 1197 down vote favorite 340I am not sure whether it is possible to scp a folder from remote to local, but still I am left with no other options. I use ssh to log into my server and from there I would like to copy the folder foo to home/user/Desktop (my local). Is there any command so that I can do this?
To use full power of scp you need to go through next steps:

How do I copy an entire directory into a directory of the same name without replacing the content in the destination directory? (instead, I would like to add to the contents of the destination folder) ssh rsync scp synchronization
Usersync , and pass -u if you want to only update files that are newer in the original directory, or --ignore-existing to skip all files that already exist in the destination. (Note the / on the source side: without it rsync would create /remote/directory/directory .)
@Anthon I don't understand your comment and I don't see an answer or comment by chandra. --ignore-existing does add without replacing, what data loss do you see? – Gilles Nov 27 '13 at 9:59
Sorry, I only looked at your first example that is where you can have data loss (and is IMHO not what the OP asked for), if you include --ignore-existing.
If you have access to the storage-server - just install openssh-server or launch rsync as a daemon here.
In my case - I could not do this and the solution was: lftp . lftp 's usage for syncronization is below:
/src/folder - is the folder on my PC, /rem/folder - is sftp://sft.domain.tld/rem/folder .
You may find man pages by the link: http://lftp.yar.ru/lftp-man.html
scp does overwrite files and there's no switch to stop it doing that, but you can copy things out the way, do the scp and then copy the existing files back. Examples:
- Copy all existing files out the way
- Copy everything using scp
- Copy the original files over anything scp has written over:
This method doesn't help when you're trying to pull files over from a remote and pick up where you left off. I.e. if the whole purpose is to save time. – Oliver Williams Dec 1 '16 at 17:58
>To copy a whole bunch of files, it's faster to tar them. By using -k you also prevent tar from overwriting files when unpacking it on the target system.
It does make a remote connection. First it tar's the source, pipes it into the ssh connection and unpacks it on the remote system. – huembi Aug 22 '16 at 21:17
[Dec 07, 2015] How to resume a large SCP file transfer on Linux
Ask Xmodulo
Originally based on BSD RCP protocol, SCP (Secure copy) is a mechanism that allows you to transfer a file between two end points over a secure SSH connection. However, as a simple secure copy protocol, SCP does not understand range-request or partial transfer like HTTP does. As such, popular SCP implementations like the scp command line tool cannot resume aborted downloads from lost network connections.
If you want to resume an interrupted SCP transfer, you need to rely on other programs which support range requests. One popular such program is rsync. Similar to scp, rsync can also transfer files over SSH.
Suppose you were trying to download a file (bigdata.tgz) from a remote host remotehost.com using scp, but the SCP transfer was stopped in the middle due to a stalled SSH connection. You can use the following rsync command to easily resume the stopped transfer. Note that the remote server must have rsync installed as well.
$ cd /path/to/directory/of/partially_downloaded_file
$ rsync -P -rsh=ssh userid@remotehost.com:bigdata.tgz ./bigdata.tgz
The '-P' option is the same as '--partial --progress', allowing rsync to work with partially downloaded files. The '-rsh=ssh' option tells rsync to use ssh as a remote shell.

Short answer: no.
...but rsync does, which is why i have aliased scp to rsync -Pravdtze ssh on my box. Yes, that's a lot of switches, which in combination produces my preferred rsync behavior. As rsync does provide a very extensive set of switches and options, i suggest you do some research on it to see what fits your needs best. Manpage is a good place to start, but there are a lot of info easily available. Here's a decent list of examples.
Edit: Actually, in that particular case you posted, the folder will be created, as that's the folder you're copying. However, if you're trying to copy it to user@remotehost:somenonexistentfolder/somefolder, then it will fail.

In this example, if scp is possible without authentication, the command will execute else it will exit as shown below.
Scp -- Secure File Transfer between UNIX machines
Scp is an updated version of an older utility named Rcp. It works the same, except that information (including the password used to log in) is encrypted.
Just like the cp command, scp will overwrite an existing destination file. In addition, if the destination is an existing directory, the copied material will be placed beneath the directory.
Also, if you have set up your .shosts file to allow you to ssh between machines without using a password as described in help on setting up your .shosts file, you will be able to scp files between machines without entering your password.
The general form of the command is:
where source-specification indicates which file or directory is to be copied, and destination-specification indicates where the copied material is to be placed.
Either the source or the destination may be on the remote machine; i.e., you may copy files or directories into the account on the remote system OR copy them from the account on the remote system into the account you are logged into.
Example:
To copy a directory, use the -r (recursive) option. Example:The format for the remote specification (source or destination) is:
where filename is the name (path) of the file or directory relative to the home (login) directory on the remote system.
The format for file specification on the local system is just:
where fname is the name (path) relative to the current working directory on that system.
Examples of remote file copies
- While logged into user on server, copy file 'letter' into file 'application' in remote account abc on sdcc3:
- While logged into abc on sdcc3, copy file 'foo' from remote account user on server into filename 'bar' in abc:
- While logged into account user on server, copy file 'garfield' from subdirectory 'comix' into filename 'fatcat' in subdirectory 'stuff' in remote account abc on sdcc3:
- While logged into account abc on sdcc3, copy file 'garfield' from subdirectory 'comix' of account user on server into subdirectory 'stuff' with the same name 'garfield':
- While logged into account abc on sdcc3 , copy subdirectory 'Section' into a new subdirectory called 'Section' in existing subdirectory 'Chapter' in account user on server:
- From account abc on sdcc3, copy entire account to ir123 on iacs5. This needs to be done from the parent directory of the account to be moved.
For more information about the scp (secure copy) command, check the on-line manual page for scp:
Copying Files with scp
To copy files between two machines, say 192.168.1.101 and 192.168.1.100, sit at 192.168.1.101 and use the following command:
scp * 192.168.1.100:
Simple as that! Assuming you are the same user id on both machines, this will copy all files in the current directory to your home directory on the destination machine, 192.168.1.100. The first thing the command will do, though, is ask you for your password on the remote system - once you supply that, then you'll see the files copied, with progress bars.
Now, if you want to copy only some files, e.g. all txt files, use a standard wildcard, like this:
scp *.txt 192.168.1.100:
Suppose you want to copy them to a destination directory other than your home directory, use:
scp *.txt 192.168.1.100:/home/username/directory
Of course, you have to have write permission on the target directory.
Suppose you want to copy files from the other machine back to the one you're on - then use this syntax:
scp 192.168.1.100:*.txt .
Scp Using Ssh Config
If you have a DNS or hosts file set up, then you can (and should) use hostnames in the command, like this:
scp mail/* mailsrvr:/home/joe/mail
This will copy the contents of the mail subdirectory (of the current directory) on this machine, to the directory /home/joe/mail on the machine mailsrvr.

[[ user@ ] host1: ] filename1 ...[[ user@ ] host2: ] filename2
Scp copies files between hosts on a network. It uses ssh for data transfer, and uses the same authentication and provides thesame security as ssh. Unlike rcp , scp will ask for passwords or passphrases if they are needed forauthentication.
Any file name may contain a host and user specification to indicatethat the file is to be copied to/from that host. Copies between tworemote hosts are permitted.
Options
- -1
- Force scp to use command 'scp1' on the remote side instead of 'scp'.This may be necessary in some situations, if the remote system has'scp2' symlinked to 'scp'.
- -ossh-options
- Ssh options passed to ssh.
- -p
- Preserves modification times, access times, and modes from the original file.
- -q
- Turn off statistics display.
- -Q
- Turn on statistics display.
- -r
- Recursively copy entire directories.
- -v
- Verbose mode. Causes scp and ssh to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems.
- -B
- Selects batch mode (prevents asking for passwords or pass phrases).
- -C
- Compression enable. Passes the -C flag to ssh to enable compression.
- -Pport
- Specifies the port to connect to on the remote host. Note that this option is written with a capital P, because -p is already reserved for preserving the times and modes of the file in rcp.
- -Spath-to-ssh
- Specifies the path to ssh program.
ENVIRONMENT VARIABLES
You can turn scp statistics on or off by setting SSH_SCP_STATS or SSH_NO_SCP_STATS environment variables. To turn on or off scp statistics for each file,use SSH_ALL_SCP_STATS or SSH_NO_ALL_SCP_STATS environment variables. The default value of the statistics can be setwhen the ssh is configured. Next the scp checks those environmentvariables and after that command line options.

DESCRIPTION
scp copies files between hosts on a network. It usesssh(1) for data
transfer, and uses the same authentication and provides the same security
asssh(1). Unlikercp(1), scp will ask for passwords or passphrases if
they are needed for authentication.
Any file name may contain a host and user specification to indicate that
the file is to be copied to/from that host. Copies between two remote
hosts are permitted.
The options are as follows:
-1 Forces scp to use protocol 1.
-2 Forces scp to use protocol 2.
-4 Forces scp to use IPv4 addresses only.
-6 Forces scp to use IPv6 addresses only.
-B Selects batch mode (prevents asking for passwords or passphras-
es).
-C Compression enable. Passes the -C flag tossh(1) to enable com-
pression.
-ccipher
Selects the cipher to use for encrypting the data transfer. This
option is directly passed tossh(1).
-Fssh_config
Specifies an alternative per-user configuration file for ssh .
This option is directly passed tossh(1).
-iidentity_file
Selects the file from which the identity (private key) for RSA
authentication is read. This option is directly passed to
ssh(1).
-llimit
Limits the used bandwidth, specified in Kbit/s.
-ossh_option
Can be used to pass options to ssh in the format used in
ssh_config(5). This is useful for specifying options for which
there is no separate scp command-line flag. For full details of
the options listed below, and their possible values, see
ssh_config(5).
