# grep_bin
`grep_bin` can search recursively a directory or multiple files for a sequence of bytes or ascii string.

## Usage
### Searching for a byte sequence in a file
`$ grep_bin fffe test.bin`

### Searching recursively a directory for a byte sequence
`$ grep_bin FFFE ~/Downloads`

### Filtering the filetypes
`$ grep_bin -f mp3 FFfe0000 ~/Downloads`

### Search for an ASCII string inside the binary
`$ grep_bin '"Hello World"' test.bin`

Search for an ASCII string with quotes included: `$ grep_bin '"This is a \"quote\""' test.bin`

### Search a byte sequence in multiple files
`$ grep_bin fFFe test1.bin test2.bin`

### Specify the number of bytes per line in the output
`$ grep_bin -c 32 "information" README.md`

Output:

grep_bin 2.0.0
LaBatata101 <labatata101@linuxmail.org>
Searches recursively a directory or multiple files for a sequence of bytes or ASCII string.

USAGE:
    grep_bin [OPTIONS] <PATTERN> <FILE>...

ARGS:
    <PATTERN>    Ascii strings should be passed inside quotes like so '"This is a string"'
                 Escaping quotes '"This is a \"quoted string\""'
                 All of these byte sequence are valid: f9b4ca, F9B4CA and f9B4Ca
    <FILE>...    The filepath

OPTIONS:
    -c <context_bytes_size>        Defines the number of bytes that will be printed in each line.
                                   [default: 16]
    -f <filetype>                  Filter the search by the file extensions.
                                   Examples of input: jpg, mp3, exe
    -h, --help                     Print help information
    -o, --print-offset             Prints only the offsets of the match.
    -p, --print-only               Prints only the filename that contais the match.
    -s, --skip-bytes <n>           Skip n bytes before searching. [default: 0]
    -V, --version                  Print version information
```
