Useful linux commands

More like a reminder. I’m gonna try to add new commands to avoid every time I forget some, the need to search for them endlessly.

To search some binary or hex pattern inside a file:

grep -obarUP "<hex-pattern>" /location

Example: 
grep -obarUP "\x6F\x62\x73\x63" .

To delete some bytes from a file, or in the case, the exact amount of bits from those hex patterns you just found:

dd if=test1.obs bs=1 skip=8 of=test2.obs

But I want to pipe out the grep’s output to other commands. Ok, change a few things and we are ready to go:

grep -rlP "\x6F\x62\x73\x63" | xargs -I '{}' echo '/{}'
