Shell script implementation turns off redundant TTY terminals _linux shell

Today to optimize the company's new deployment servers, found that the TTY terminal has 6, in order to save a bit of memory, decided to leave only a TTY terminal, the others are off, but CENTOS6 and centos5 terminal closure method completely changed, and I am also lazy, do not want a set of a Taiwan, Writing down this foot would have saved time.

System: CentOS 6

Close TTY Terminal script:

Cat pkill.sh

Copy Code code as follows:

#!/bin/bash
Sed-i ' s/\/dev\/tty\[1-6\]/\/dev\/tty\[1-1\]/g '/etc/init/start-ttys.conf
Sed-i ' s/\/dev\/tty\[1-6\]/\/dev\/tty\[1-1\]/g '/etc/sysconfig/init
Ttypid= ' PS auxw|grep tty|grep-v grep |grep tty[2-6]|awk ' {print $NF} '
For i in $ttypid;d o initctl stop tty tty= $i;d One

To execute permissions after saving:

Copy Code code as follows:

chmod +x pkill.sh

The script is very simple, before you use the best to determine their own system, to avoid unnecessary errors.
