sh equivalent of FILE

Question

Is there a sh equivalent of __FILE__, to give me the pathname of the currently executing file? POSIX solutions preferred, bash acceptable, thanks.

Try using $0.

This is not equivalent to `__FILE__` if you are doing it in a file that is sourced from another file. – mxcl Aug 15 '12 at 14:20

This will grab both the file and the directory

# !/bin/sh

# store where we are
__PWD__=$(pwd)
# go to the current file (i.e. this file)
cd $(dirname $0)
# gives the file name, __FILE__
echo $0
__FILE__=$0
# gives the directory name, __DIR__
echo $(dirname $0)
__DIR__=$(dirname $0)
# this has been a test of the Linux filesystem; we now return you to your previous program.. :)
cd $__PWD__

Just a thought:

#!/usr/bin/env bash

# "$0" will expand to the name of the script, as called from the command line
readlink -f $0

That will be incorrect if the script is called via the $PATH variable. – Bill Lynch Jul 23 '10 at 14:26
Note that `readlink` isn't entirely portable. OSX (and presumably BSD in general?) have a completely different version - where `-f` isn't supported. Rather, where `-f` means something different (and not helpful here). – Telemachus Jul 23 '10 at 14:29
`echo $(readlink -f $0)` works fine on OSX 10.6, just tested it. – miku Jul 23 '10 at 14:30

Why are you using `echo`. Doesn't `readlink -f $0` by itself work? – Dennis Williamson Jul 23 '10 at 14:43
@The MYYN You must have gnu's `coreutils` installed without the `g` prefixes. Here's what happens when I run that command: `readlink: illegal option -- f` (Yes, I'm on 10.6. I actually have gnu's `readlink` as well, but only under the alias `greadlink`. http://pastie.org/1057557 for an example.) – Telemachus Jul 23 '10 at 20:29
