felipe.vinturinIn awk, this maybe works:


Code:
echo "Enter first_name:"read fawk -v varF="${f}" 'BEGIN { INGNORECASE = 1 } $2 == varF {print "Name: " $2,$1}' file

this code is not working

'not working' in what way? Nothing happens? Your system explodes? Giant aliens appear from the sky, laying waste to the surrounding area and exhorting people to buy Betamax?

At least post the output and/or error messages you are seeing.

Maybe you are facing an error because of that ",".

Try this one:
Code:
echo "Enter first_name:"
read f
awk -v varF="${f}" 'BEGIN { INGNORECASE = 1 } $2 == varF {print "Name: " $2 "," $1}' file

Also, as CarloM commented, whenever you face an error, don't forget to post it. Smilie
