I'm encountering an issue where I am trying to get the size of a terminal by using scripts. Normally I would use the command
tput cols inside the console, however I want to be able to accomplish this feature by strictly using scripts.
As of now I am able to detect the running console and get its file path. However I'm struggling to use this information to get the console's width. I've attempted using the command
tput, but I'm fairly new to Linux/scripts so therefore don't really know what to do.
The reason for doing this is I want to be able to setup a cron entry that notifies the console of its width/columns every so often.
This is my code so far:
#!/bin/bash #Get PID of terminal #terminal.txt holds most recent PID of console in use value=$(</home/test/Documents/terminal.txt) #Get tty using the PID from terminal.txt TERMINAL="$(ps h -p $value -o tty)" echo $TERMINAL #Use tty to get full filepath for terminal in use TERMINALPATH=/dev/$TERMINAL echo $TERMINALPATH COLUMNS=$(/home/test/Documents/get_columns.sh) echo $COLUMNS
#!/usr/bin/env bash echo $(/usr/bin/tput cols)
The normal output of
/dev/pts/terminalnumber, for example
