Have you ever run
git diff in your terminal to see the code changes you plan to
git add and commit, but found that seeing all of them in one big diff is overwhelming?
git add -p (the ‘patch’ option) – it will display your code changes in small chunks, and for each one it will ask you whether you want to add it to be committed (git calls this "staging"). Give it a try when you next have some changes ready to commit!
Bonus tip: After running
git add -p you can type
? and hit enter to see the help for this option.
If you want to selectively discard a specific piece of your total diff, you can use the same
-poption, but on the
git checkoutcommand. Be very sure about what you are doing when doing this, however, since it will discard the change completely as if you never wrote it.
It can be useful when you have a diff with many parts and you want to only discard a few of them but you don’t want to have to select
yfor all of the ones you want when using git add
I can see
git checkout -p working well alongside
git add -p – I’m looking forward to using it in my git workflow.
Thanks for the tip, Martin!
