scp or sftp copy multiple files with single command

I'd like to copy files from/to remote server in different directories. For example, I want to run these 4 commands at once.

scp remote:A/1.txt local:A/1.txt
scp remote:A/2.txt local:A/2.txt
scp remote:B/1.txt local:B/1.txt
scp remote:C/1.txt local:C/1.txt

What is the easiest way to do that?

When I made a script, I had to put password for each command. Can I avoid it?
Avoid repeating password this way: scp remote:"A/1.txt A/2.txt B/1.txt C/1.txt" local:./
stackoverflow.com/a/23748561/874188 (nominated as duplicate of this one) has a nice additional technique.
I would suggest that you have a look at rsync, maybe it can help you in this case and many upcoming cases. Then, to avoid entering passwords (let alone multiple times) you should read about ssh public/private keys, e.g. digitalocean.com/community/tutorials/how-to-set-up-ssh-keys--2
Example based on @JohnMudd 's answer: scp root@192.168.56.120:'/etc/openvpn/ca.crt /etc/openvpn/client/client0.crt /etc/openvpn/client/client0.key /etc/openvpn/client/ta.key' ./ .

Copy multiple files from remote to local:

$ scp your_username@remote.edu:/some/remote/directory/\{a,b,c\} ./

Copy multiple files from local to remote:

$ scp foo.txt bar.txt your_username@remotehost.edu:~
$ scp {foo,bar}.txt your_username@remotehost.edu:~
$ scp *.txt your_username@remotehost.edu:~

Copy multiple files from remote to remote:

$ scp your_username@remote1.edu:/some/remote/directory/foobar.txt \
your_username@remote2.edu:/some/remote/directory/

Source: http://www.hypexr.org/linux_scp_help.php


The first command omitted an ending ".", and '{a,b,c}' is equal to \{a,b,c\}.
I think OP is trying to copy multiple files in multiple local folders to multiple remote folders, these examples won't do the job, as they all will scp files to ~ or ./ only.
Beware: no spaces after the commas within the curly braces. I just spent 10 minutes trying to figure out why my command was not working and it was because of spaces.
@duleshi {a,b,c} is not exactly equal to \{a,b,c\} when copying from remote to local, for the first requires password for each file while the second requires password only once.
@MarceloVentura, @duleshi: Also, I'd like to add that using \{a,b,c\} will transfer the files in a single connection/batch (since they'll be expanded on the remote host), while using {a,b,c} will open multiple connections, and the overhead is quite noticeable when transferring many files

From local to server:

scp file1.txt file2.sh username@ip.of.server.copyto:~/pathtoupload

From server to local:

scp -T username@ip.of.server.copyfrom:"file1.txt file2.txt" "~/yourpathtocopy"


This should be the answer on top, since the server doesn't ask for the password for each file :)
Not working on client on Ubuntu 18 (zsh). Not sure where this should work. ``` (venv) ➜ git:(master) ✗ scp root@172.29..xxx.yyy:"/usr/local/bin/kubectl /root/.kube/config" /tmp/ root@172.29..xxx.yyy's password: protocol error: filename does not match request ```
@motagirl2 The top answer doesn't ask for the password for each file as long as you're escaping the curly brackets with the backslash. This answer gives me an error that the file cannot be found.
The server to local does not work. How it has 87 up votes, I have no clue.
the second one works on my machines but only without the -T option

You can copy whole directories with using -r switch so if you can isolate your files into own directory, you can copy everything at once.

scp -r ./dir-with-files user@remote-server:upload-path

scp -r user@remote-server:path-to-dir-with-files download-path

so for instance

scp -r root@192.168.1.100:/var/log ~/backup-logs

Or if there is just few of them, you can use:

scp 1.txt 2.txt 3.log user@remote-server:upload-path

Does this work if my destination is root and I'm doing the etc directory like for example: scp -r /backups/etc root@linuxbox:/ where my source is a very sparse directory with things like "hosts" and nginx/sites-available etc ?

As Jiri mentioned, you can use scp -r user@host:/some/remote/path /some/local/path to copy files recursively. This assumes that there's a single directory containing all of the files you want to transfer (and nothing else).

However, SFTP provides an alternative if you want to transfer files from multiple different directories, and the destinations are not identical:

sftp user@host << EOF
  get /some/remote/path1/file1 /some/local/path1/file1
  get /some/remote/path2/file2 /some/local/path2/file2
  get /some/remote/path3/file3 /some/local/path3/file3
EOF

This uses the "here doc" syntax to define a sequence of SFTP input commands. As an alternative, you could put the SFTP commands into a text file and execute sftp user@host -b batchFile.txt


This the only answer that actually answers the question. Thanks. I've been Googling and analyzing the scp manual for way too long trying to find this feature, and I guess scp doesn't have it.
This seems to be the best, most flexible answer. Note: I got tripped up until I realized that I needed to use a full path like /home/vagrant/Code/ instead of ~/Code/.
This is the best answer, just don't forget to add - r for directories
This only works if you have public key authentication setup.

The answers with {file1,file2,file3} works only with bash (on remote or locally)

The real way is :

scp user@remote:'/path1/file1 /path2/file2 /path3/file3' /localPath

Fantastic! I use non-bash shells sometimes and this helps immeasurably. Not only the real way, but the right way.
Globbing with {…, …, …} works in many shells, not only in Bash. However this works in any shell so is clearly better.
Needs more quoting. Those paths can contain spaces.
There we go! I'd upvote that many times, but I just can do it once! Thank you Vouze!
Well, your '/path1/file1 /path2/file2 /path3/file3' produces a "protocol error: filename does not match request" due to the space. Use the -T option.

After playing with scp for a while I have found the most robust solution:

(Beware of the single and double quotation marks)

Local to remote:

scp -r "FILE1" "FILE2" HOST:'"DIR"'

Remote to local:

scp -r HOST:'"FILE1" "FILE2"' "DIR"

Notice that whatever after "HOST:" will be sent to the remote and parsed there. So we must make sure they are not processed by the local shell. That is why single quotation marks come in. The double quotation marks are used to handle spaces in the file names.

If files are all in the same directory, we can use * to match them all, such as

scp -r "DIR_IN"/*.txt HOST:'"DIR"'
scp -r HOST:'"DIR_IN"/*.txt' "DIR"

Compared to using the "{}" syntax which is supported only by some shells, this one is universal


Thanks for helping with spaces in the file names. I was using {} approach so I also had to escape them with \ after quoting.
In case you want to use the tilde character (~) for your home directory in paths. Note how the ~ and / must be outside the quotes. ``` scp -r robwaa@192.168.1.101:'~/"bin/set-vpn-kill-switch" ~/"bin/flush-iptables"' ~/"" ```
The {} syntax makes it easier to copy multiple files from the same directory, is there any way to do this with scp -r so that "FILE1" "FILE2" can be relative paths and not absolute paths to the files?

Problem: Copying multiple directories from remote server to local machine using a single SCP command and retaining each directory as it is in the remote server.

Solution: SCP can do this easily. This solves the annoying problem of entering password multiple times when using SCP with multiple folders. Consequently, this also saves a lot of time!

e.g.

# copies folders t1, t2, t3 from `test` to your local working directory
# note that there shouldn't be any space in between the folder names;
# we also escape the braces.
# please note the dot at the end of the SCP command

~$ cd ~/working/directory
~$ scp -r username@contact.server.de:/work/datasets/images/test/\{t1,t2,t3\}  .

PS: Motivated by this great answer: scp or sftp copy multiple files with single command

Based on the comments, this also works fine in Git Bash on Windows


P.S. do not add spaces between items. i.e. \{t1, t2, t3\} ------> I wasted ten minutes here...lol
This is the best answer because when you escape the braces it will be interpreted as a single command by and it won't ask for the password for each transfer
@Amaynut yes, exactly! That certainly saves lot of time and effort :)

The simplest way is

local$ scp remote:{A/1,A/2,B/3,C/4}.txt ./

So {.. } list can include directories (A,B and C here are directories; "1.txt" and "2.txt" are file names in those directories).

Although it would copy all these four files into one local directory - not sure if that's what you wanted.

In the above case you will end up remote files A/1.txt, A/2.txt, B/3.txt and C/4.txt copied over to a single local directory, with file names ./1.txt, ./2.txt, ./3.txt and ./4.txt


Wouldn't this overwrite the content of A/1.txt with the content of B/1.txt on the local machine?
good point.. adjusted example (so now it wouldn't overwrite) and added description. Thanks.
Brace expansions like this are a Bash feature, and not portable to e.g. POSIX sh.
@tripleee, thanks. it might not be posix, but it works not only in bash. I use ksh all the time and it works there too.
You can also mix dirs and files by doing: local$ scp -r remote:{A/1.txt,A/2.txt,B/3.txt,C/4.txt,D,F} ./

Copy multiple directories:

scp -r dir1 dir2 dir3 admin@127.0.0.1:~/

question was how to copy from remote directory to local one, not other way around.
S
Simson

You can do this way:

scp hostname@serverNameOrServerIp:/path/to/files/\\{file1,file2,file3\\}.fileExtension ./

This will download all the listed filenames to whatever local directory you're on.

Make sure not to put spaces between each filename only use a comma ,.


This is good when the extension is the same. It could be written as /path/to/files/\\{file1.ext,file2.ext,file3.ext\\} if the files have different extensions. Note to PowerShell people (now that MS has joined the party) you need to use ` to escape instead: /path/to/files/`{file1.ext,file2.ext,file3.ext`}
How about scp multiple files with the same extension? I have tried "{file1,file2}".pdf and {"file1,file2"}.pdf but it doesn't work: No such file or directory. However, your first option for one file does work. But, for more than one file, how do you do that? Please help!

scp remote:"[A-C]/[12].txt" local:

thanks, but it is just an example, and the actual file or directory name is more complex. But I have a list of them.
Can you describe those by a regular expression?
Is it possible to preserve the same directory structure in target directory by using regular expression?
Yes, you should be able to do that with -r option to scp. And you can preserve other attributes (like time stamp) with -p option.

Is more simple without using scp:

tar cf - file1 ... file_n | ssh user@server 'tar xf -'

This also let you do some things like compress the stream (-C) or (since OpenSSH v7.3) -J to jump any times through one (or more) proxy servers.

Avoid using passwords by coping your public key to ~/.ssh/authorized_keys (on server) with ssh-copy-id (on client).

NOTE: I apologize in advance for answering only a portion of the above question. However, I found these commands to be useful for my current unix needs.

Uploading specific files from a local machine to a remote machine:

~/Desktop/dump_files$ scp file1.txt file2.txt lab1.cpp etc.ext your-user-id@remotemachine.edu:Folder1/DestinationFolderForFiles/

Uploading an entire directory from a local machine to a remote machine:

~$ scp -r Desktop/dump_files your-user-id@remotemachine.edu:Folder1/DestinationFolderForFiles/

Downloading an entire directory from a remote machine to a local machine:

~/Desktop$ scp -r your-user-id@remote.host.edu:Public/web/ Desktop/

In my case, I am restricted to only using the sftp command. So, I had to use a batchfile with sftp. I created a script such as the following. This assumes you are working in the /tmp directory, and you want to put the files in the destdir_on_remote_system on the remote system. This also only works with a noninteractive login. You need to set up public/private keys so you can login without entering a password. Change as needed.

#!/bin/bash

cd /tmp
# start script with list of files to transfer
ls -1 fileset1* > batchfile1
ls -1 fileset2* >> batchfile1

sed -i -e 's/^/put /' batchfile1
echo "cd destdir_on_remote_system" > batchfile
cat batchfile1 >> batchfile
rm batchfile1

sftp -b batchfile user@host

In the specific case where all the files have the same extension but with different suffix (say number of log file) you use the following:

scp user_name@ip.of.remote.machine:/some/log/folder/some_log_file.* ./

This will copy all files named some_log_file from the given folder within the remote, i.e.- some_log_file.1 , some_log_file.2, some_log_file.3 ....

scp uses ssh for data transfer with the same authentication and provides the same security as ssh.

A best practise here is to implement "SSH KEYS AND PUBLIC KEY AUTHENTICATION". With this, you can write your scripts without worring about authentication. Simple as that.

In my case there were too many files with non related names.

I ended up using,

$  for i in $(ssh remote 'ls ~/dir'); do scp remote:~/dir/$i ./$i; done
1.txt                                         100%  322KB   1.2MB/s   00:00
