hi,
i am writing a bash script and need some help.
i need to substring a variable containing grep

i have John Doe:999-999-9999 in a line.
the line is given by user input, which searches a file
and i need to print out the number part only and not the name.

i did
set A = `grep -i "$FN $LN"` datafile
// FN and LN are user inputs for the name
set N = `echo $A|awk '{print substr($0,12,12)}'`
echo $N

this case werks in the terminal but not when i put it in my bash script.

Something that works in a terminal, but not in a script usually means you need to set your path within the script. Try that first.
