This post is part of my Today I learned series in which I share all my web development learnings.

Ashley Williams tweeted that !! in commit messages will be replaced with the last executed command.

It turns out this is nothing git specific but rather command line specific and there are a lot more:

  • !! - last command
  • !1 - first entry in history
  • !-1 - last entry in history
  • !ssh - last command starting with ssh
  • !:1 - first argument of last command

For the case of git this works only when using -m though. ;) If you want to read more about this Digital Ocean published a nice article on this topic.
