Looking at the jq github repo led me to also find ag, an ack-grep replacement.

Skip ag and go straight to rg (ripgrep).

Now check out ripgrep (command `rg`) https://github.com/BurntSushi/ripgrep https://github.com/BurntSushi/ripgrep, the ag/ack killer ;).

I like ag, but unless I'm missing something, ack has this killer flag which ag lacks: --output=expr Output the evaluation of expr for each line (turns off text highlighting) If PATTERN matches more than once then a line is output for each non-overlapping match. For more information please see the section "Examples of --output". Basically, it allows you to use captured groups in the output: cat file | ag '(\w+) (\d+)' --output '$1 is $2 years old' On the other hand, ag allows multiline matching. So I end up using ag and ack together frequently.

    sed doesn't support the same PCRE regex ack or ag
    - mVChr 10y ago
      No, but the `-r` option makes it use extended regex[1]. Here's some PCRE: cat file | perl -ne 'print if s/(\w+) (\d+)/\1 is \2 years old/' My only point is sometimes old school standard tools are plenty. 1: https://www.gnu.org/software/sed/manual/sed.html#Extended-regexps https://www.gnu.org/software/sed/manual/sed.html#Extended-re...

        Right...but there's a point in having a tool that does PCRE, and all the things useful in grep, in one command, rather than kicking out to Perl.
        a3n 10y ago
        Agreed, it's nice to consolidate disparate functionality into a single invocation. But when I saw mVChr's sed line, and then again the perl line, I was reminded "Oh, right, old school." And I wondered for the Nth time how much of old school has been unknowingly reinvented, and how many times. Nevertheless, I like the new(er) tools in this thread too.

  ripgrep has that with -r/--replace.
