10 handy Bash aliases

  1. How many times have you needed to unpack a .tar file and couldn’t remember the exact arguments needed? Aliases to the rescue! Just add the following to your .bash_profile file and then use untar FileName to unpack any .tar file.
alias untar='tar -zxvf '
  1. Want to download something but be able to resume if something goes wrong?
alias wget='wget -c '
  1. Need to generate a random, 20-character password for a new online account? No problem.
alias getpass="openssl rand -base64 20"
  1. Downloaded a file and need to test the checksum? We’ve got that covered too.
alias sha='shasum -a 256 '
  1. A normal ping will go on forever. We don’t want that. Instead, let’s limit that to just five pings.
alias ping='ping -c 5'
  1. Start a web server in any folder you’d like.
alias www='python -m SimpleHTTPServer 8000'
  1. Want to know how fast your network is? Just download Speedtest-cli and use this alias. You can choose a server closer to your location by using the speedtest-cli –list command.
alias speed='speedtest-cli --server 2406 --simple'
  1. How many times have you needed to know your external IP address and had no idea how to get that info? Yeah, me too.
alias ipe='curl ipinfo.io/ip'
  1. Need to know your local IP address?
alias ipi='ipconfig getifaddr en0'
  1. Finally, let’s clear the screen.
alias c='clear'

As you can see, Bash aliases are a super-easy way to simplify your life on the command line. Want more info? I recommend a quick Google search for “Bash aliases” or a trip to GitHub.
