Assuming that semicolon (;
) was a typo in the question and you actually meant colon (:
) this would be the correct regex:
- anchor at beginning of line (
^
) - capture one-or-more non-colon characters (
([^:]+)
) - match must end on a colon (
:
)
#!/usr/bin/perl
use warnings;
use strict;
while (<DATA>)
print "$1n" if /^([^:]+):/;
exit 0;
__DATA__
asfmqwdbd/ilcp
asfmqwdbd/ilcp:dftqclk_repasfmq
asfmqwdbd/ilcp;dftqclk_repasfmq
Test run:
$ perl dummy.pl

Assuming from your question you want the output like this
"asfmqwdbd/ilcp"
for this you can use "^([S]+):" and then use $1.
