How to determine the execution path of a script in BASH
This weekend I was looking for ways to make a BASH script that works as a pitcher for the Oriole and needed to know the execution path itself script.
For a moment I did not know how, but The Great Totuma enlightened me and I remembered the basic parameters of any script ... it was then when he came to my mind the famous
$ 0

$ 0 contains the full path of running script. This parameter, along with another little program will allow us to do the magic. Application
receives a route and returns the same route but without the last component (RTFM 
for more information.) What we do is pass dirname $ 0 and then concatenate the name of any program / script and voila! We will have our automatic launcher. Would something like
# / usr / bin / bash
CWD = $ (dirname $ 0)
sh $ CWD / otro_programa.sh
# / usr / bin / bash
CWD = $ (dirname $ 0)
sh $ CWD / otro_programa.sh
