These are just documentation for me because I don’t want to remember them. It is not a guide for anything.

• remap right alt key with context menu button (I miss the context button on my Thinkpad)

  // add this to your startup script to make it permanent
  xmodmap -e "keycode  108 = Menu"
  

• awk

  awk '/regex/'
  awk '!/regex/'
  
  awk 'BEGIN{a=5; b=2.5; print a+b}'
  awk '{sub(/:/, "-")} 1' // subtitution
  awk '{gsub(/:/, "-")} 1'
  

• List network devices

  Win:
  arp -a
  

• Make VS Code remember Github credentials; Easier if you are working with multiple accounts for work and personal.

  git config credential.helper store
  

• Install Node

• Install NPM

  curl -L https://npmjs.org/install.sh | sudo sh
  

• Print exit code of previous-run program

  echo $?

• PATH manipulation

  env | grep PATH
  
  echo $PATH
  
  export PATH=<previous-paths>:<new-path>
