NAME
realpath - Print the resolved (absolute) path
VERSION
This document describes version 0.004 of realpath (from Perl distribution App-realpath), released on 2021-11-26.
SYNOPSIS
% realpath [OPTION]... <FILE>...
% abspath [OPTION]... <FILE>...
To demonstrate how realpath
, quickabspath
, and relpath
give you different results:
% pwd
/home/ujang
% mkdir dir1
% ln -s dir1 sym1
% cd sym1
% realpath . ;# gives absolute path and resolve symlinks (-P, the default)
/home/ujang/dir1
% realpath -P . ;# ditto (-P is the default)
/home/ujang/dir1
% abspath . ;# an alias for realpath
/home/ujang/dir1
% realpath -L foo ;# uses PWD for working directory (-L)
/home/ujang/sym1/foo
% quickabspath . ;# gives absolute path but does not resolve symlinks
/home/ujang/sym1
# relpath does the opposite, converting to relative path
% relpath /home/ujang/dir1
.
% relpath /home/ujang/sym1
../sym1
DESCRIPTION
This is the Perl-based implementation alternative for the Unix utility realpath (also aliased to abspath). It uses Cwd's realpath
(which is the same as abs_path
) function. The function works by reading "." (the current directory) and moving upwards until it reaches the root directory, resolving symlinks along the way.
When -L (--logical
) option is given, will use PWD environment variable and not resolve symlinks.
EXIT CODES
0 on success.
99 on command-line options error.
OPTIONS
--physical, -P
--logical, -L

CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
