I am sick of having to escape things when I want to search for part of an html tag.

How can I ack search for exactly what I type without having to escape stuff?


ack-grep 'console.log(foo'

I get:

Unmatched ( in regex; marked by <-- HERE in m/console.log( <-- HERE par/
  • Use a different shell? Put it in quotes? Place your search string in a file, I suspect ack-grep can get the string from a file. Perhaps you can even could even get the search via stdin.

  • @Zoredache I added a better example.. I don't want to have to escape (.. and what do you mean by better shell?

  • I mean all the chracters you are complaining about are handled by your shell (bash/zsh/whatever). The problem has nothing to do with the tool. The problem is that the shell is not sending what you type.

You have to escape the regex.

ack 'console\.log\(foo'

(You should escape the . so that you don't match "consoleflog", because . matches any single character)

And if you would rather not do that, do this to quote every metacharacter automatically.

ack -Q 'console.log(foo'

    \Q does not work on my server. ack '\Qconsole.log(foo' ack: Invalid regex '\Qconsole.log(foo': Unmatched ( in regex; marked by <-- HERE in m/\Qconsole.log( <-- HERE foo/

  • I was mistaken about the \Q example and have removed it from the answer. Thanks, @Sébastien. Jul 14 '17 at 15:07
