Remove file extension and path from a string in Perl
For portably getting the basename of a file given a full path, I'd recommend the File::Basename
module, which is part of the core.
To do heuristics on file extensions I'd go for a regular expression like
(my $without_extension = $basename) =~ s/\.[^.]+$//;
Assuming that the path separator is '/'
, you can do it with a pair of substitutions:
$name =~ s{^.*/}{}; # remove the leading path
$name =~ s{\.[^.]+$}{}; # remove the extension
You can also write that as a single substitution:
$name =~ s{^.*/|\.[^.]+$}{}g;
Although others have responded, after reading a bit on basename per rafl's answer:
($file,$dir,$ext) = fileparse($fullname, qr/\.[^.]*/);
# dir="/usr/local/src/" file="perl-5.6.1.tar" ext=".gz"
Seems to solve the problem in one line.
Are there any problems related with this, opposed to the other solutions?
