  "github_readme_excerpt": "# bgrep\n\nI\u0027m terribly annoyed by the fact that grep(1) cannot look for binary\nstrings. I\u0027m even more annoyed by the fact that a simple search for\n\"binary grep\" doesn\u0027t yield a tool which could do that. So I wrote one.\n\nFeel free to modify, branch, fork, improve.\n\n## Building\n\n```sh\nmake\n```\n\n## Installing\n\n```sh\nmake install # to /user/local/bin, or\nmake install PREFIX=~/.local\n```\n\nOr, if you need it quickly,\n\n```sh\ncurl -L \u0027https://github.com/tmbinc/bgrep/raw/main/bgrep.c\u0027 | gcc -O2 -x c -o $HOME/.local/bin/bgrep -\n```\n\n## Usage\n\n```\nbgrep [-r] [-B bytes] [-A bytes] [-C bytes] \u003chex\u003e [\u003cpath\u003e [...]]\nbgrep [-r] -f \u003cpattern\u003e [-m \u003cmask\u003e] [\u003cpath\u003e [...]]\n```\n\n| Option       | Description                                              |\n| ------------ | -------------------------------------------------------- |\n| `-B \u003cbytes\u003e` | print `\u003cbytes\u003e` of context before each match            |\n| `-A \u003cbytes\u003e` | print `\u003cbytes\u003e` of context after each match             |\n| `-C \u003cbytes\u003e` | print `\u003cbytes\u003e` of context before **and** after a match |\n| `-r`         | recurse into directories                                |\n| `-f \u003cfile\u003e`  | read the search pattern from a file instead of `\u003chex\u003e`  |\n| `-m \u003cfile\u003e`  | read a mask file (wildcard bytes for the pattern)       |\n\nWhen no path is given, `bgrep` reads from standard input.\n\n### Examples\n\nSearch a file for the byte sequence `0x42 0x42 0x42`:\n\n```sh\nbgrep 424242 firmware.bin\n```\n\nRecurse through a directory:\n\n```sh\nbgrep -r 424242 ./images\n```\n\n## License\n\nBSD 2-Clause.
