Bash output analysis script
I want to create a script to analyse each output from a task while it is running and launch a sub-function if a specific error message is found at any point or to continue as normal.

Code:
#!/bin/bash 
read checker <<< $('Running process')
if [ "$checker" == "Error message" ] ; then 
'Sub-function' 
elif "continue as normal"
fi

Does this process run quickly and quit, or does it slowly print a number of lines?

If it's the latter, which I suspect, I'd do this:

Code:
process | while read LINE
do
        case "$LINE" in
        *Error*)
                echo "Something happened"
                ;;
        esac
done

Yeah the latter, normally 1-2 outputs per second. Thanks, I'll try that.
