[SOLVED] Select exact regex with awk

Hello everyone,

I would like to use awk to select an exact regex (pattern) in a file, and print the line including the regex.

Unfortunately, as the regex is a variable "$f", I can't use the following expression:

Quote:

/regex/{print} file

I have found this form of awk to pass the variable argument "$f" to awk:
Quote:

awk -v regex="$f" '$0 ~ regex {print}' file

But it is not selecting the exact regex pattern.
Would anyone know how to select the exact pattern?
