I am working on making a git command I use more useful. A common task I do is to grep my git rev-list --all. I wrote (aka cut and pasted another StackExchange answer) git command to do this for me.

~/bin/git-search:

!/bin/bash

function _search() {

    git rev-list --all | (

        while read revision; do

            git grep -F $1 $revision

        done

    )

}

_search $1

The output from this looks like:

f26ce56cf6b17401292c494f906b2b6a9071ca75:filename.py:grepped string

I usually take these results and run git show along with the commit and file path to see that particular version of the file. git show takes the input of {COMMIT HASH}:path/to/file.

What I'd ideally like is to have my git function stick a whitespace where the second : is, which would allow me more easily copy and paste the output of git-search into git show, ie:

f26ce56cf6b17401292c494f906b2b6a9071ca75:filename.py grepped string

I'd like to use BASH for this as I am already using BASH. My initial solution was to use Python but that seems needless to me. I just am not sure how best to achieve this in BASH.

sed 's/:/ /2'

This would change the second : character to a space.

You could stick that in as an extra stage of your function's pipeline:

#!/bin/sh



git rev-list --all |

while read revision; do

    git grep -F "$1" "$revision"

done |

sed 's/:/ /2'

(I actually deleted the function as it didn't seem to be needed; note also the quoting of the variable expansions; oh, and it's a /bin/sh script since it's not using any bash-specific features (neither did yours, except for the unneeded function keyword))

  That's perfect! And thanks for the other improvements as well. I wasn't aware sed could do this. Does that mean I can swap out the 2 for a 3 to remove the third instance? I only knew about d, e, and g. Guess I have a lot of sed to learn still.

  @IanPringle Yes, you can swap out the 2 for 3 or any other positive integer. There is no d flag to the s command in sed (not even in GNU sed). I assume that you're thinking about the d commad in sed.

  @kusalanada That's great! Yes, I guess that's true the d replaces the s. Thanks again!
