Main git commands

This is the list of most useful git commands.

Stage changes by hunk

Git will interactively let you add, skip, or split diff hunks.

$ git add -p

Where:

• y - stage this hunk
• n - do not stage this hunk
• q - quit; do not stage this hunk or any of the remaining ones
• a - stage this hunk and all later hunks in the file
• d - do not stage this hunk or any of the later hunks in the file
• g - select a hunk to go to
• / - search for a hunk matching the given regex
• j - leave this hunk undecided, see next undecided hunk
• J - leave this hunk undecided, see next hunk
• k - leave this hunk undecided, see previous undecided hunk
• K - leave this hunk undecided, see previous hunk
• s - split the current hunk into smaller hunks
• e - manually edit the current hunk
• ? - print help

Checkout to a certain tag

First check if the tag list is updated.

$ git tag --list

If the desired tag is not in the list, update the tag list

$ git fetch --all --tags --prune

And then, checkout the correct tag.

$ git checkout tags/<tag_name>

Waring: When you checkout a tag, the head of the repo is pointing to a uncertain location, so the commits could not have the desired effect. If you whant to commit some changes, make sure you are in an active branch before the commit.
