Bash execute ssh command on background

bash

Example 1:

I want to run a script test.sh on local host
and the test.sh access server "eos" via SSH, on the background.
The test.sh contains :

#!/bin/bash
ssh eos 'sh -c "(echo "hello" > yang.txt"'

Solution:
Use nohup command on local machine:

nohup ./test.sh &

Result:
In the yang.txt file on server eos, there is one word "hello".

Example 2:

The test.sh takes one parameter :

#!/bin/bash
ssh eos " echo $1 >> yang.txt"

Solution:
Use nohup command on local machine:

nohup ./test.sh "song" &

Result:
In the yang.txt file on server eos, there is one word "song".

Explanation [2]:

Variables in single-quotes are not evaluated. Use double quotes:

ssh pvt@192.168.1.133 "~/tools/run_pvt.pl $BUILD_NUMBER"

The shell will expand variables in double-quotes, but not in single-quotes.
This will change into your desired string before being passed to the ssh command.
