I'm terribly annoyed by the fact that grep(1) cannot look for binary strings. I'm even more annoyed by the fact that a simple search for "binary grep" doesn't yield a tool which could do that. So I wrote one. Feel free to modify, branch, fork, improve. Re-licenses as BSD. To install: curl -L 'https://github.com/tmbinc/bgrep/raw/master/bgrep.c' | gcc -O2 -x c -o $HOME/.local/bin/bgrep - usage: bgrep [-B bytes] [-A bytes] [-C bytes] <hex> [<path> [...]] -B: bytes_before -A: bytes_after -C: bytes_before and bytes_after
