I'm trying to develop a perl script that looks through all of the user's directories for a particular file name without the user having to specify the entire pathname to the file.

For example, let's say the file of interest was `data.list`. It's located in `/home/path/directory/project/userabc/data.list`. At the command line, normally the user would have to specify the pathname to the file like in order to access it, like so:

`cd /home/path/directory/project/userabc/data.list`

Instead, I want the user just to have to enter `script.pl ABC` in the command line, then the Perl script will automatically run and retrieve the information in the `data.list.` which in my case, is count the number of lines and upload it using curl. the rest is done, just the part where it can automatically locate the file
