Could you give an example of something useful one could do with ack's --output feature?
The manual's a little light on the details.
All it says is:
--output=expr
Output the evaluation of expr for each line
What expression are they talking about? A regular expression? If so, how is that different from a normal grep?
- neild 16y agoA Perl expression. You could use this for sed-like activities: # Print included files. ack --output '$1' '#include <(.*)>' You could presumably do much trickier things as well, since the --output argument can contain any Perl expression.
- betterthangrep 16y agoThat's a great example. I just replaced it as the example in the Top 10 List on the front of betterthangrep.com. Thanks.
