The git add -p command allows interactive staging of hunks or parts of a file ( https://git-scm.com/book/en/v2/Git-Tools-Interactive-Staging).
Is there a way to stage a hunk non-interactively? Say, I have these hunks:
$ git diff diff --git a/test.txt b/test.txt index 77e67ac..34eabb1 100644 --- a/test.txt +++ b/test.txt @@ -1,4 +1,4 @@ -this is the first change +this is the first change, don't stage it! @@ -6,5 +6,5 @@ this is the first change -this is the first change +this is the second change, stage it! It would be nice to run a single command like git add -p 2 to stage the second hunk without going through the interactive menu.
NOTE: One solution is mentioned here (How to stage chunks non-interactively in git?), but it involves multiple commands and an additional step of editing a patch file.
EDIT: When would this be useful? Say I was editing a long and repetitive JSON file, and after running git diff, I know I want to stage every other hunk. I don't want to go through each hunk individually; I just want to tell git "stage the 2nd, 4th, 6th, 8th, etc. hunks".
