readlink

See the current Perl documentation for readlink.

Here is our local, out-dated (pre-5.6) version:


readlink - determine where a symbolic link is pointing



readlink EXPR

readlink



Returns the value of a symbolic link, if symbolic links are implemented. If not, gives a fatal error. If there is some system error, returns the undefined value and sets $! (errno). If EXPR is omitted, uses $_.
