Do Math From The Command Line

Posted By Weston Ganger

I always have a terminal open and sometimes I need to add or multiply some values really quick. So I looked into it and made a bash function so I can do this. Add this to your .bashrc


math(){
  awk "BEGIN { print "$1"}"
}

Be sure to reload your bashrc by running ‘exec bash’ or ‘source ~/.bashrc’ or open a new tab And now when you want to do some math right quick.


math 4.2*6.5
math 56+34

### if using parenthesis be sure to wrap it as a string
math "127/(5*3)"

Hope this helps some of you. See the stack exchange link for more methods
