<div>Hi.</div><div>I am not a bash expert, I just want to share how to follow symbolic links I've seen in a script:</div><div><br></div><div><br></div><div>#!/usr/bin/env bash<br># Find our location<br>SELF_LOCATION=$(cd "$(dirname "$0")" ; pwd)<br>
<br># Was this invoked as a link ?<br>if [ -L "$0" ]<br>then<br> LINKTO=$(/usr/bin/readlink "$0")<br><br> # Is the link a relative path<br> if [[ "${LINKTO}" = /* ]]<br>
then<br> # absolute path so just invoke it<br> exec "${LINKTO}" "$@"<br> else<br> # invoke by prepending our folder<br> exec "${SELF_LOCATION}/${LINKTO}" "$@"<br>

readlink -f is a GNU-ism, apparently. And since OSX isn't GNU (it's<br>
mostly FreeBSD userland), not surprising it breaks.<br>
<br>
