How to run a shell script with parameters using airflow's SSH operator

I'm trying to run a Pentaho job in a remote system using airflow. I was able to use airflow's SSH operator to SSH into remote system and run the shell script but I'm wondering how to pass parameters to the shell script.

For example the shell command looks like

sh -C "$PENT_HOME"/kitchen.sh -file="$PENT_HOME/Details.kjb" -level=Basic > $logFolder/date -u +"%Y-%m-%dT%H:%M:%SZ"-Details.log 2>&1

My DAG script for running a simple shell script without parameters is

t1 = SSHOperator(ssh_conn_id='SSH-dev',
    task_id='ssh_operator',
    command='/opt/scripts/test.sh ',
    dag=dag)

command argument takes any bash/shell command, so you can do this for example:

t1 = SSHOperator(ssh_conn_id='SSH-dev',
    task_id='ssh_operator',
    command='/opt/scripts/test.sh arg1 arg2',
    dag=dag)

In your case:

t1 = SSHOperator(ssh_conn_id='SSH-dev',
    task_id='ssh_operator',
    command='bash "$PENT_HOME"/kitchen.sh -file="$PENT_HOME/Details.kjb" -level=Basic > $logFolder/date -u +"%Y-%m-%dT%H:%M:%SZ"-Details.log 2>&1',
    dag=dag)
