Simple note of different usable hacks for everyday work with Git.
Save repo credentials to save some time while push/pull changes
user@host:~/your/repo/path$ git config credential.helper store
Use GPG sign commits
How to generate GPG key? Read here
user@host:~/your/repo/path$ gpg2 --list-secret-keys --keyid-format LONG <your_email>
user@host:~/your/repo/path$ git config --global user.signingkey <here_is_key_id>
user@host:~/your/repo/path$ git config --global gpg.program gpg2
To sign commit:
user@host:~/your/repo/path$ git commit -S -a -m "commit_comment"
In case of error gpg: signing failed: Inappropriate ioctl for device try to use this command:
export GPG_TTY=$(tty)
Auto sign commits
If you don't want to type the -S flag every time you commit, you can tell Git
to sign your commits automatically:
$ git config --global commit.gpgsign true
See the differences between current version and previous
Difference between current version and previous commit
# Linux
git diff @^
# Windows
git diff @~
Difference between current version and specific commit:
git diff commit_id HEAD
Diff could be used with tags also:
git diff v1.01 HEAD
