The first line they start with is utter nonsense. find -print0 will not produce lines, but records (or strings) separated by NUL. But grep is a tool working with lines (separated by LF). No mystery that it cannot work. Using -print0 is necessary if you have filenames containing LF chars. Otherwise just use -print and grep and everything should be fine. Now how do we handle NUL separated records? That required a bit of thinking, the Unix world is based so much on lines. Without extensive testing the following awk program seems to work: BEGIN { RS = "\0" } $0 ~ regexp Call with awk -v 'regexp=what I search for' In their script that would be awk -v "regexp=$1" Edit: Credits for s/whitespace/LF chars/ go to user hnfong
