Execute multiple commands after SSH connection to the server

Have you ever encountered yourself connecting to a cloud server? After connecting with ssh, you find that some of your gadgets can't be used.

For example, go build cannot be used, because when we install and configure the golang environment, the configuration is written in the file /etc/profile , so we need source look at /etc/profile

So is it possible to automatically execute this type of command immediately when ssh connects to the server?

Our wisdom is endless, and there are many gadgets. Today I will tell you how to do multiple commands SSH连接服务器后执行

1 separated by semicolons

Use semicolons ; to separate commands

• with 1 command

   ssh User@Host 'source /etc/profile'

• Comes with multiple commands

   ssh User@Host 'source /etc/profile ; uptime'

2 separated by pipe symbols

Use pipes | to separate commands

• with 1 command

   ssh User@Host 'source /etc/profile'

• Comes with multiple commands

   ssh User@Host 'source /etc/profile | uptime'

3 Use the way of writing EOF

Same for one/many commands

 ssh User@Host << EOF
> ls -al
> source /etc/profile
> EOF

4 Ways to use scripts

There are more ways to use scripts. For example, there is a script myinit.sh under /home/admin/code/

myinit.sh

 #!/bin/bash

source /etc/profile
ls -al

remote connection server

 ssh User@Host 'bash -s' < /home/admin/code/myinit.sh

The above four methods are available on demand.
