pshell whoami

Create a plain text file script1.txt containing:

cd Demo/sean
get testfile1

pshell -i script1.txt

Run the following script if you have bash ... sorry Windows users (without WSL.)

#!/bin/bash

pshell "rmdir /idontexist"

if [ $? == 0 ]; then
   echo "All good - proceed further!"
else
   echo "Operation failed!"
fi

Which produces:

Error from server: The namespace '/idontexist' does not exist or is not accessible
Operation failed!

This would typically be a job script on (eg) Pawsey HPC - where you would be doing all such work in a Linux environment.

The idea is that if something in your data setup pipeline fails - don't waste any valuable cpu time on it.

You will need two scripts here, one to run pshell (which would be submitted as a job) and another to supply multiple commands to pshell.

The second script is needed as, by default, pshell will try to upload into your current working directory (/projects) which you do not have permission to alter.

First script, call it: upload.txt

cd /projects/Demo/sean
put testfile

Then we can run this:

#!/bin/bash

pshell -i upload.txt

if [ $? == 0 ]; then
   echo "All good - proceed further!"
else
   echo "Operation failed!"
fi
