I am wondering how to write the awk one liner :

cat <filename> | awk '$2 ~ /GRHL3/{print NR"\t"$0}'

which prints out the( or any) line that has the string "GRHL3" in it as well as its respective line number

the perl one liner for the same task I have so far is perl -ne 'print if /GRHL3/' <filename>

What do I have to add so that it will also print out the line number ... I feel like $. has to go somewhere? Thanks so much!! Also does someone know of a good web resource where you can look this sort of thing up (specifically about one liners).
