I want to set an environment variable relative to the location of a script. I can easily find and set it for the duration of the script (test.sh):
#!/bin/bash export MY_VARIABLE=$(dirname $0) echo MY_VARIABLE is : $MY_VARIABLE
MY_VARIABLE is : .
If I want to use the variable in other scripts, I need to set it with the source command. This is of course not working because I'm now not calling the test.sh script, but the source command.
dirname: illegal option -- b usage: dirname path MY_VARIABLE is :
Is there a way to define an environment variable in a script that can then be used with the source command?
