perl v5.10.0 Cwd $VERSION = '3.2501'; in /home/albert abs_path "testfolder" returns /home/albert/testfolder abs_path "../testfolder" returns undef abs_path "testfolder/a" returns undef /home/albert/testfolder /home/testfolder and /home/albert/testfolder/a are all invalid path but if the parameter passed to abs_path does not contain "/", it will return the concatenated path directly without checking existence. -- missing the days we spend together

The behavior of Cwd::abs_path() appears to have changed somewhat since this ticket was originally filed. From blead roughly 2013-11-23: ##### $ ./perl -Ilib -MCwd=abs_path -wE 'say abs_path("testfolder")' /home/jkeenan/perl/testfolder $ ./perl -Ilib -MCwd=abs_path -wE 'say abs_path("../testfolder")' /home/jkeenan/testfolder $ ./perl -Ilib -MCwd=abs_path -wE 'say abs_path("testfolder/a")' Use of uninitialized value in say at -e line 1. #####
