I am transforming some binary files and grepping a value in them:
od -t uL * | grep 0000
this is showing the matches that I am after but it's not showing the filename, and if I do use grep
with the -H
flag I only get 'standard input':
od -t uL * | grep -H 0000
(standard input):xxx 0000
(standard input):yyy 0000
How can I get the original filename returned?
That information is lost by the time grep
is run, so you might have to loop over the files yourself
for f in *; do
od -t uL "$f" | awk -v f="$f" '/0000/ {print f":"$0}'
done
