getpwuid

getpwuid uid

Retrieves the passwd file entry with the user ID uid. The return value in list context is:

($name,$passwd,$uid,$gid,$quota,$comment,$gcos,$dir,$shell)
If you want to do this repeatedly, consider slurping the data into a hash using getpwent.

In scalar context, getpwuid returns the username.
