How to Copy a File to Multiple Directories in Linux
While learning Linux, it is always the norm for newbies to keep on typing several commands to accomplish a simple task. This is understandable especially when one is just getting accustomed to using the terminal.
However, as you look forward to becoming a Linux power user, learning what I would refer to as “shortcut commands” can significantly reduce time wasting tendencies.
In this article, we will explain an easy way, using a single command to copy a file into multiple directories in Linux.
In Linux, the cp command is used to copy files from one directory to another, the easiest syntax for using it is as follows:
# cp [options….] source(s) destination
Consider the commands below, normally, you would type two different commands to copy the same file into two separate directories as follows:
# cp -v /home/aaronkilik/bin/sys_info.sh /home/aaronkilik/test # cp -v /home/aaronkilik/bin/sys_info.sh /home/aaronkilik/tmp
Assuming that you want to copy a particular file into up to five or more directories, this means you would have to type five or more cp commands?
To do away with this problem, you can employ the echo command, a pipe, xargs command together with the cp command in the form below:
# echo /home/aaronkilik/test/ /home/aaronkilik/tmp | xargs -n 1 cp -v /home/aaronkilik/bin/sys_info.sh
In the form above, the paths to the directories (dir1,dir2,dir3…..dirN) are echoed and piped as input to the xargs command where:
-n 1– tells xargs to use at most one argument per command line and send to the cp command.
cp– used to copying a file.
-v– enables verbose mode to show details of the copy operation.
Try to read through the man pages of
xargs commands to find useful and advanced usage information:
$ man cp $ man echo $ man xargs
