I don’t know if you have any experience in managing hundreds of Linux operating systems. Although you can log in without password through the ssh private key, I really seem to smash the keyboard when entering the server IP address dozens of times a day. So later I learned to be lazy to log in using shell scripts. The idea is just to pass the last ip address to the shell script, and you can log in as fast as possible. If there are IP addresses of multiple different subnets, just create the corresponding shell script.
How to use
[zongming@monitor ~]$ ssh5 113
Environment variables
echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/games:/home/zongming/sh
shell script
cat /home/zongming/sh/ssh5
Copy the codeThe code is as follows:
#!/bin/bash
#script_name:
#description:login ssh
#last_update:20130725 by zongming
if [ $# -eq 1 ];then
ssh -v [email protected].${1}
else
echo "Error:return value 1" && exit 1
