I search for things a lot, especially in my code. Or even worse - someone else’s
code. For years
grep served as an amazing tool for this: fast, simple, and
yet powerful. That was until I discovered
ack for myself. An incredibly easy
grep implementation built to work with large (or not really) code
A lot can be said to enforce superiority of
grep when it comes to
working with code, and it’s all said here: ack’s features.
Amazing thing is -
ack doesn’t even need a tutorial. Learning progression is
natural and “just happens” by researching necessary use cases as the need
ack has a great manual entry).
Here’s a typical use example for
ack --shell 'gr[ae]y'
Searches all shell script files in the current code tree for any occurrences of
“gray” or “grey”. It will search
.zsh, and just about dot-anything;
ack will even check shebang lines for you.
Ease of use, the fact that it’s ready to use out of the box, extensive file
types, native support for Perl’s regular expressions:
ack does really good
job at searching through code.
