Re: [SLE] bash script

[James D. Parra]

#!/bin/bash

cd /opt/location
exec filename

Thank you for all of your responses. They all worked perfectly.

Two little comments.

First, "cd /opt/location && exec filename" is a bit better, so if the directory does not exist, the command will not be executed. Only a good habit to take: and this one saved my life a few times! :-)

Second, someone said that "exec" was not needed. This is true. Yet, it is a tiny bit faster to use "exec", because the called program will then _replace_ the shell, and when the program will terminate, that will be the end of the story. Otherwise, without the "exec", when the program will terminate, the shell will have to regain control for nothing else than terminating itself. Nowadays, such optimisations are anachronic!
