$> The effective uid of this process. For example: $< = $>; # set real to effective uid ($<,$>) = ($>,$<); # swap real and effective uids You can change both the effective uid and the real uid at the same time by using POSIX::setuid() . Changes to $> require a check to $! to detect any possible errors after an attempted change. $< and $> can be swapped only on machines supporting setreuid() . Mnemonic: it's the uid you went to, if you're running setui
