I’ve been using homebrew for as long as I can remember using macOS. I recently learned about cleaning up old and outdated files using the brew cleanup command. I also run it sequentially with update and upgrade commands:
brew update && brew upgrade && brew cleanup
Sometimes, I periodically upgrade packages that are installed using brew. Thus, I thought, why not add an alias such as below in my .zshrc file:
alias hbc="brew update && brew upgrade && brew cleanup"
This helps me to update and upgrade outdated packages, and clean up old files. Now, whenever I have to run all three tasks, I simply run hbc in the terminal.
Upgrading outdated packages periodically saves me from a situation when installing a new package, homebrew will upgrade all outdated packages first.
