How do you return a value with grep ?

If for example I want to store the linenumber of a particular word occurrence, how do you do it ?

I tried this

grep -on searchstring filename > LINENUM

wondering whether LINENUM would be stored in the shell, but it wasn't. Any suggestions please.

That would save the result to a file called "LINENUM".

If by "stored in the shell" you mean in a variable, try:

Code:

LINENUM=$(grep -on searchstring filename)
echo $LINENUM
