Return resolved physical path.
Syntax
realpath [-q] [path ...]
Key
-q warnings will not be printed when realpath(3) fails..
The realpath utility uses the realpath(3) function to resolve all symbolic links, extra ‘/’ characters and references to /./ and /../ in path.
If path is absent, the current working directory (‘.’) is assumed.
The realpath utility exits 0 on success, and >0 if an error occurs.
Show the physical path of the /dev/log directory silencing warnings if any:
$ realpath -q /dev/log
/var/run/log
Show the physical path of ~/:
$ realpath ~/
/Users/chenelo
Set the variable $BASE to the directory where a script is currently saved:
#!/bin/bash
BASE="$(dirname $(realpath $0))"
“A real decision is measured by the fact that you've taken a new action. If there's no action, you haven't truly decided” ~ Tony Robbins
