在远程服务器外壳上执行命令

Question

I am running a simple command on remote server using ssh on shell.

I am currently logged in myHost01 and i'm running this command on myHost02

The expected result is this is a test myHost02 . HOWEVER, I get this is a test myHost01

This is my command

sshpass -p root ssh -q root@127.0.0.2 "echo this is a test `hostname`"

I don't know why it is taking the hostname of the server I'm running the command from!!!

---

It is also noticeable that when I run this

sshpass -p root ssh -q root@127.0.0.2 "hostname"

I get myHost02 (which is the correct output)

Answer 1

Pass the command in single quotes, like below. The double quotes cause the shell to execute command substitution hostname (locally) in-place and pass the resultant string this is a test myHost01 to ssh

sshpass -p root ssh -q root@127.0.0.2 'echo this is a test `hostname`'
