Returning a value from awk to bash
Hi
I am a newbie starting bash and I have a simple need to return the result of an operation from awk to bash. basically I want to use awk to tell me if "#" exists in a string, and then back in bash, i want to do an IF statement on this return in order to do other things. In my bash shell I have this;

Code:
moduleID="#analog"
read a < $(echo | awk -v r=$moduleID '{print index(r,"#")}')

when I run this i get

1: No such file or directory

Running awk to process a single line is overkill. Running awk to process a single word is decadence. Smilie

BASH has its own string operations that work much faster than loading, running, and quitting another programming language to do so.

Code:
case "$STRING" in
*#*) echo "# exists in string" ;;
*) echo "# does not exist in string" ;;
esac

I recommend corona's suggestion. But here is what you should modify in order to get your code work:
Code:
read a <<< $(awk -v r="$moduleID" 'BEGIN{print index(r,"#")}')
