Grep with colours

Blush

With Blush, you can grep with colours, many colours!

Usage

Match Method

This method shows matches with the given input:

$ blush -b "first search" -g "second one" -g "and another one" files/paths

Any occurrence of first search will be in blue, second one and and another one are in green.

Colouring Method

With this method all texts are shown, but the matching words are coloured. You can activate this mode by providing --colour or -C argument.

Piping

Blush can also read from a pipe:

$ cat FILENAME | blush -b "print in blue" -g "in green" -g "another green"
$ cat FILENAME | blush "some text"

Arguments

+---------------+----------+------------------------------------------------+
|    Argument   | Shortcut |                     Notes                      |
+---------------+----------+------------------------------------------------+
| --colour      | -C       | Colour, don't drop anything.                   |
| N/A           | -i       | Case insensitive matching                      |
| N/A           | -R       | Recursive                                      |
| --no-colour   | N/A      | Doesn't colourize matches.                     |
| --no-color    | N/A      | Same as --no-colour                            |
| --no-filename | -h       | Suppress the prefixing of file names on output |
+---------------+----------+------------------------------------------------+

File names or paths are matched from the end. Any argument that doesn't match any files or paths are considered as regular expression. If regular expressions are not followed by colouring arguments are coloured based on previously provided colour:

$ blush -b match1 match3 FILENAME

Notes

• If no colour is provided, blush will choose blue.
• If you only provide file/path, it will print them out without colouring.
• If the matcher contains only alphabets and numbers, a non-regular expression is applied to search.

Colour Groups

You can provide a number for a colour argument to create a colour group:

$ blush -b1 match1 -b2 match2 -b1 match3 FILENAME

All matches will be shown as blue. But match1 and match3 will have a different background colour than match2. This means the numbers will create colour groups.

You also can provide a colour with a series of match requests:

$ blush -r match1 match3 -g match2 FILENAME

Colours

You can choose a pre-defined colour, or pass it your own colour with a hash:

+-----------+----------+
|  Argument | Shortcut |
+-----------+----------+
| --red     | -r       |
| --green   | -g       |
| --blue    | -b       |
| --white   | -w       |
| --black   | -bl      |
| --yellow  | -yl      |
| --magenta | -mg      |
| --cyan    | -cy      |
| --#11bb22 | --#1b2   |
+-----------+----------+

You must put your complex grep into quotations:

$ blush -b "^age: [0-9]+" FILENAME
