3.2.63 getpwuid

getpwuid UID

This function does the same thing as getpwuid(3): it translates a numeric user id to the corresponding passwd file entry. 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.
