What is the easiest way to add a tag? For example, in my script that creates a config file, I have the line



echo "Variable = $arr[0]" >> $CFG_FILE



So, this takes the respective entry from another script and assigns it to Variable. What if I don't want it to necessarily be in order, but instead a user could say,



--Variable 273893



in the calling script that would then assign that value to "Variable".



I'm not too familiar with coding, so explicit help would be much appreciated. Thanks!
