+How to Copy a File to Multiple Directories in Linux
+============================================================
+
+[While learning Linux][1], 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][2] is used to copy files from one directory to another, the easiest syntax for using it is as follows:
+
+```
+# cp [options….] source(s) destination
+```
+
+Alternatively, you can also use the [advanced-copy command][3], which shows a progress bar while copying [large files/folders in Linux][4].
+
+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
+```

+][5]

+
+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][6], a pipe, xargs command together with the cpcommand 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 xargscommand where:
+
+1.  `-n 1` – tells xargs to use at most one argument per command line and send to the cp command.
+2.  `cp` – used to copying a file.
+3.  `-v` – enables verbose mode to show details of the copy operation.

+
+Try to read through the man pages of `cp`, `echo` and `xargs` commands to find useful and advanced usage information:
+
+```
+$ man cp
+$ man echo
+$ man xargs
+```
+
+That’s all, you can send us questions in relation to the topic or any feedback through the comment form below. You may also want to read about the [progress command][8] which helps to monitor the progress of (cp, mv, dd, [tar][9], etc.) commands that are presently running in Linux.
