Ways to find records based on their first letter awk Unix using variable

原文 2019-12-11 18:26:27 7 1 unix/ awk

awk -F":" -v var="$letterinput" '$3 ~ /^$var/{printf"%-s\n",$3}' NSN_DATA

this is what i have come up with so far. I can get it to work with switch out ^var with ^A but i need it to allow the user to set letter.
