Tips & Tricks

fish_update_completions run this once in a while to make the fish prompt aware of available commands and parameters

Update Script

If you run this more often makes then you can put an alias to this file in your `~/.fish_aliases we talked about above.

#!/usr/bin/env fish

echo 'start updating ...'

echo 'updating homebrew'
brew update
brew upgrade
brew cleanup

echo 'updating fish shell'
fisher up
fish_update_completions

echo 'updating npm'
npm update -g

echo 'checking Apple Updates'
/usr/sbin/softwareupdate -ia

exit 0

iTerm default screen

I use the terminal a lot and one windows is just not enought for me. You can setup your default window in iTerm2 like you want, mine looks like this:

One big windows on the left for coding or more detailed stuff and two split windows on the right to quickly fire some commands.

To Setup your window like you prefare just right click in the iTerms windows and say "Split Pane Vertically or Horizontally" to your needs. When you like it go to "Window -> Save Window Arrangment". For the last step go to "Preferences -> Arrangment" and set it to default. Next time you open iTerms it starts with your prefared awesome window setup.
