git aliases

In a Git alias, the exclamation point ! tells Git: * “Don’t prepend the git command; run ‘as-is’ in the system shell (Bash/Zsh).”
With !: You can string multiple commands together using &&, use pipes (|), or even run non-git commands like echo.
Without !: Git expects a standard Git subcommand. For example, alias.st status just runs git status.
When you define an alias without the !, Git automatically prepends git to whatever you wrote.

• For example: alias.sview "stash show -p"
  • Git executes: git stash show -p
• If you had written alias.sview "git stash show -p",
  • Git would try to execute: git git stash show -p, which would have failed.

1. Simple alias: Leave git out, don’t use !.
2. Complex alias (pipes, logic, or multiple commands): Start with !, and you must include git for every command in the chain.

• git fetch -p ~ This tells your local git: “If the branch was deleted on GitHub, forget about it here too”
• git branch –merged main ~ Lists branches main already contains.
• Excludes your current branch and the actual main branch so you don’t accidentally delete the branch you’re standing on.
• Deletes the remaining branches

xargs is a powerful tool that takes the output of one command and turns it into arguments for another.

• The Chain:
  • git branch --merged produces a list of names.
• The Problem:
  • You can’t just pipe text into git branch -d.
  • It doesn’t know what to do with the text.
• The Solution:
  • xargs grabs those names and “pastes” them onto the end of the command.
  • So it effectively executes: git branch -d branch1 branch2 branch3.
• The -r flag:
  • This stands for --no-run-if-empty.
  • If no branches are merged, xargs will stay quiet.
  • Without -r, it would try to run git branch -d with no name, which would throw an error.

• simple short cut to save typing “stash show -p”
• this alias shows what’s been stashed (example below)
