I have the following scenario, I have script that runs bash script on another remote machine

The command to ssh is

ssh knode@192.18.48.0 'bash -s' < test.sh

test.sh

#/bin/sh
bash ./trigger.sh

trigger.sh (Remote server)

docker build -t nginx .

I need to change the directory before executing the script trigger.sh. For instance like this:

ssh knode@192.18.48.0 'cd /pipeline' 'bash -s' < test.sh 

I tried with cd but I am getting error bash line 0:cd: too many arguments

Help is highly appreciated how to accomplish this, or is there any other way for the above scenario.

  • Can't you add the cd to either test.sh or trigger.sh?

    Maybe ssh knode@192.18.48.0 'cd /pipeline && bash -s' < test.sh? (untested)

You can add the cd to the ssh command:

ssh knode@192.18.48.0 'cd /pipeline && bash -s' < test.sh 

Alternatively, you can add it to either one of the scripts you call. So either test.sh:

#/bin/sh
cd /pipeline
bash ~/trigger.sh

Or trigger.sh:

cd /pipeline
docker build -t nginx .
