I have tried to copy a file test.txt to multiple directories with one command:

cp ~/test.txt ~/folder1 ~/folder2

But I didn't succeed. Is there a way to do that in one command so I can copy a file or even a folder to multiple directories?

Not easily. You may want to look into "rsync" for efficiently updating multiple existing copies of a folder –  Thorbjørn Ravn Andersen Mar 13 at 10:15

Try learning a bit of bash-script. It can get very useful: for dest in folder1 folder2; do cp ~/test.txt ~/"$dest"; done –  Shahbaz Mar 13 at 11:08

cp can copy from multiple sources, but can't copy to multiple destinations. See man cp for more info.

The only bash command that I know which can copy/save to multiple destinations is tee.

You can use it in your case as follows:

tee ~/folder1/test.txt ~/folder2/test.txt < ~/test.txt

Note that tee also writes the input to the standard output (stdout). So if you don't want this, you can prevent it by redirecting standard output to /dev/null as follow:

tee ~/folder1/test.txt ~/folder2/test.txt < ~/test.txt >/dev/null

Clever, that's cheating! :) –  terdon Mar 11 at 17:13
    
@terdon Only if you consider that I/O redirection is an independent command :) –  Radu Rădeanu Mar 11 at 17:18

+1, clever! And if you use the >/dev/null works with binary files too, without messing up the terminal... –  Rmano Mar 11 at 17:30

@nux Don't forget to use -r option with cp in case of directories –  Radu Rădeanu Mar 11 at 19:08

@nux: tee unlike cp copies only file's content ignoring its mode, ownership, timestamps. To avoid repeating the filename: f=text.txt; <~/$f tee ~/folder1/$f > ~/folder2/$f –  J.F. Sebastian Mar 13 at 9:26

Another way to achieve a copy to multiple locations is the following command :

find dir1 dir2 -exec cp file.txt {} \;

If dir1 or dir2 have sub-directories that you don't want the file copied into, add -maxdepth 0option :

find dir1 dir2 -maxdepth 0 -exec cp file.txt {} \;

Nice solution! Seems to me more perfect than with tee. –  Danatela Mar 11 at 17:55

Indeed, no redirection is involved and it's still one command. –  Sylvain Pineau Mar 11 at 18:03

@SylvainPineau In fact there are 3: one is find and for two times (in this case) cp. Not to say that find need a lot of time. –  Radu Rădeanu Mar 11 at 18:13

If the definition of a "command" is an "exec" call, maybe, but this is "one command" in my book. –  kojiro Mar 11 at 22:27

technically two commands (find and cp) but no pipes so "looks" like one command ;-) –  Michael Martinez Mar 12 at 19:28

The command

cp ~/test.txt ~/folder1 ~/folder2

tries to copy two files (~/test.txt and ~/folder1) to the destination folder2. (And if ~/folder2 exists and is a directory you will have an "omitting directory" warning).

If you want to make multiple copies of the file test.txt, you have to use a loop or multiple commands...

for i in ~/folder1 ~/folder2; do cp  ~/test.txt $i; done 

(...and be careful if you have spaces embedded in the file names, you'll need quoting).

To copy whole directories you have to use the -r option:

for i in ~/folder1 ~/folder2; do cp -r ~/folder3 $i; done

this will create ~/folder1/folder3 and ~/folder2/folder3 with all the files included.

For the passing reader: According to the spec, a for loop is a compound command. Therefore this is still one command, and meets all the requirements for the question. –  kojiro Mar 11 at 22:35
    
@nux, I do not agree on the corrections. 1) the two capitals are wrong, my intent was to interleave the commands into the phrase. 2) the ellipsis is a matter of style; please let my style in. –  Rmano Mar 13 at 16:06

ok , am sorry man , i thought it will look better . –  nux Mar 13 at 16:09

You can create a help script , or you can do it with xargs and a print function (in this case, echo ):

echo firstDir secondDir | xargs -n 1 cp test

This will make each directory as an argument to the cp function , using test file as a parameter.

After a long search this work like a Charm also !

for dir in *; do [ -d "$dir" ] && cp /path/file.txt "$dir" ; done

This will copy file.txt to every directory in your current location in terminal.

for dir in *; do [ -d "$dir" ] && cp -rf /path/folder "$dir" ; done

This will copy a folder to every sub directory in your current location in terminal.

I share it hope it helps others too .

In zsh, you can use for i in *(/); ... to loop over all the subdirectories, so you can avoid the [ -d ... test. Extended globbing is one of the reason I like it over bash. –  Rmano Mar 12 at 2:43
    
can your right the code again in a command –  nux Mar 12 at 12:13
    
In zsh, the first command of this answer can be simplified as for dir in *(/); do cp /path/file.txt "$dir"; done. See zsh.sourceforge.net/Intro/intro_2.html –  Rmano Mar 12 at 14:01

You can eliminate the test in any Bourne derived shell with for dir in */; –  Henk Langeveld Mar 13 at 8:05

Any problem with this:

cp source dest1
cp source dest2

In the general case, there are more than two directories. You wouldn't want to pass the afternoon copying around the same file manually, would you? :) –  edwin Jul 16 at 16:31
