Linux – Silencing Linux console output

consolelinuxtty

I installed a minimalist distribution for my mom to use, it uses rungetty to autologin and an init script that just does 'startx'. Everything works great but when she goes to shutdown, it drops back to the console for a while before turning off (Old PC).

Is there a way to pipe or silence all output to tty1/console. When X closes, the screen should be blank and then turn off.

Thanks

Haven't tried it, but you should be able to add "console=/dev/null" to the kernel parameters in grub or lilo. If not, try console=ttyS0 to redirect to the serial port (assuming you don't have anything connected to the serial port, maybe a non-existant serial port would be safer such as console=ttyS7).

When you type: ls, the command knows that the output is being displayed to your tty, and enabled color. When the command detects output being sent elsewhere, its going to strip the color escape codes.

So to enable color when piping output, use either ls --color, or ls -G on mac.

Then for less, you will need to append the -R flag, which maintains ANSI color escape chars.

ls -la --color | less -R

That should yield the results you are looking for.

Got it. I added the redirection operator in the shell command itself inside the script.

echo "SELECT COUNT(*) FROM test" | hive 2>&1

The script too worked.

script -c ./myscript.sh output.txt
