in reply to symbolic link and absolute path

You don't need readlink. Simply use abs_path. 

$ cd /Users/nick

$ echo 'hi' > /tmp/foo

$ ln -s /tmp/foo ./foo

$ perl -MCwd=abs_path -E 'say abs_path("./foo")'
/private/tmp/foo

$ perl -MCwd=abs_path -E 'say abs_path("/Users/nick/foo")'
/private/tmp/foo

The way forward always starts with a minimal test.

    Thanks ikegami and lnickt for the help. Using abs_path directly without readlink did solve the problem.

    And sorry for the bug in my program. I posted on the windows and I ran my code on linux. So I just typed the code here without checking. I indeed used Cwd qw(abs_path).
