NAME

abspath - Print the resolved (absolute) path

VERSION

This document describes version 0.004 of abspath (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.
