alias myips="ifconfig | sed -En 's/127.0.0.1//;s/.*inet (addr:)?(([0-9]*\.){3}[0-9]*).*/\2/p'"
shows a listing of your IP addresses, works great if you have multiple /dev/eth* (OSX/nix)
Ha ha I have this one:
alias PANIC="espeak 'OH NO, the sky is falling'"
Everyone in the office just rolls their eyes
Here are a few more of my favorite aliases.
Show/hide hidden files in the macOS Finder:
alias show="defaults write com.apple.finder AppleShowAllFiles -bool true && killall Finder"
alias hide="defaults write com.apple.finder AppleShowAllFiles -bool false && killall Finder"
Limit ping to five ECHO_REQUEST packets:
alias ping='ping -c 5'
Display drives and space in human readable format:
alias drives='df -h'
Run this one in ~/ to discover what folders are using the most space:
alias usage='du -h -d1'
Colorize grep output
alias grep='grep --color=auto -n'
Clear the screen (can’t live without this one!)
alias c='clear'
That’s all, folks!
