Get The Number Of Columns And Rows In A Terminal Window With ENV Vars

ENV Vars

Both `bash`` and `zsh`` set environmental vars for the number of columns and lines/rows in a terminal window. For example:

Code
echo $COLUMNS

-- results

56
Code
echo $ROWS

-- results

Notes

  • Not all shells set these ENV vars. Determining that is left as an exercise for the reader

  • There's also al `tputs` command is that can provide the info (link below)
