There are a number of modules that return an absolute path without resolving anything.

use Path::Tiny qw( path ); my $abs = path($0)->absolute;

For example, launching the script using ./a.pl or perl a.pl from /home/ikegami/foo would result in /home/ikegami/foo/a.pl.

But note that launching the script using ../bar/a.pl or perl ../bar/a.pl from /home/ikegami/foo would result in /home/ikegami/foo/../bar/a.pl. That's because /home/ikegami/foo/../bar/a.pl can't be safely reduced to /home/ikegami/bar/a.pl because /home/ikegami/foo might be a symlink.

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
