These postings aim to reduce the number of repeated questions as well as allow the community to review and update the answers. The latest version of the complete perlfaq is at http://faq.perl.org . -------------------------------------------------------------------- 5.15: How can I translate tildes (~) in a filename? Use the <> ("glob()") operator, documented in perlfunc. Versions of Perl older than 5.6 require that you have a shell installed that groks tildes. Later versions of Perl have this feature built in. The "File::KGlob" module (available from CPAN) gives more portable glob functionality. Within Perl, you may use this directly: $filename =~ s{ ^ ~ # find a leading tilde ( # save this in $1 [^/] # a non-slash character * # repeated 0 or more times (0 means me) ) }{ $1 ? (getpwnam($1))[7] : ( $ENV{HOME} || $ENV{LOGDIR} ) }ex; -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq.

The perlfaq-workers also don't have access to every operating system or platform, so please include relevant details for corrections to examples that do not work on particular platforms.
