I use this alias all the time, "Make PR" which creates a draft PR from the current branch and opens your browser to it. Assumes macOS + the GitHub CLI is installed:

  alias mkpr='git push && gh pr create -d -f -B develop | grep https | xargs printf -- '%s/files' | xargs open'

Or "merge develop upstream changes":

  alias mduc='CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD) && git checkout develop && git pull && git pull --tags && git checkout ${CURRENT_BRANCH} && git merge develop'

Or, "Git add and commit" -- add all changes and a commit message like "Foo bar" in one step like "$gac Foo bar"

  function gac ()
  {
    git add-commit -m "$\*" 
  }

Which assumes this git alias

  add-commit = !git add -A && git commit
