The short answer is yes, you can create a subdirectory using Perl's mkdir command. Below is a small program that reads the STDIN for a string, and then appends that string to an existing directory. This new directory is passed to the mkdir() command.

Two things I noticed while coding up this example: 1) Even though I'm on Windows, I was able to run this code using "/" as the path separator, instead of "\" (which has to be escaped with another "\"). I leave this an exercise for you. 2) The chop() is necessary to remove the trailing newline from my input string. I noticed in the original post the presence of $_, and this could be an issue for you. If in doubt, print the "$_" value using print "[$_]", so you can see if your variable has leading or trailing characters.

Good luck.

Just a note, to clarify. chop() removes the last character in a string, regardless of what it is, and returns it. If what you are trying to do is remove the newline, then what you want to do is use chomp() which is far less invasive and ONLY removes what is defined in the special variable $/, which contains the current INPUT_RECORD_SEPARATOR.

Post your perl code. Make sure to use the code tags when posting code.
