Hello Anonymous Monk,

if you want to use the regex be sure to use an anchor to just remove a dot in the beginning of the string:  /^\./ being the dot a special regex char you need to escape it.

For a more robust solution use File::Spec file_name_is_absolute and rel2abs

# something like.. $path = File::Spec->rel2abs( $path ) unless File::Spec->file_name_is_a +bsolute( $path )

    Note that the rel2abs approach will only give the same result if / is the CWD. Otherwise it's a different result:

    #!/usr/bin/env perl use strict; use warnings; use File::Spec; chdir '/tmp'; my $path = './root/git/common/crt_del/cert/DEFAULT.pem'; $path = File::Spec->rel2abs ($path) unless File::Spec->file_name_is_absolute ($path); print "$path\n";
