Unix AWK command - multiple character as a single delimiter

Question

I am trying to use two data pipeline, || , as delimiter in AWK command. But I am unable to do it. I have a file in which I have to consider two data pipeline as delimiter, just like considering TAB or COMMA as delimiter.

Answer 1

Just tell awk to interpret the | literally with [] :

awk -F'[|][|]' ...

Example:

» echo "1 || 2" | awk -F'[|][|]' '{ print $2 }'
