Remarks

Where can I learn about Bash scripts?

Beginners/BashScripting to get started.
Awesome Bash to go deeper.

How do I set a variable so that it can be read by subsequent scripts and tasks?

To learn more about defining build variables in a script, see Define and modify your build variables in a script.

To learn more about defining release variables in a script, see Define and modify your release variables in a script

Examples

Create test.sh at the root of your repo. We recommend creating this file from a Linux environment (such as a real Linux machine or Windows Subsystem for Linux) so that line endings are correct. Also, don't forget to chmod +x test.sh before you commit it.

#!/bin/bash
echo "Hello World"
echo "AGENT_WORKFOLDER is $AGENT_WORKFOLDER"
echo "AGENT_WORKFOLDER contents:"
ls -1 $AGENT_WORKFOLDER
echo "AGENT_BUILDDIRECTORY is $AGENT_BUILDDIRECTORY"
echo "AGENT_BUILDDIRECTORY contents:"
ls -1 $AGENT_BUILDDIRECTORY
echo "SYSTEM_HOSTTYPE is $SYSTEM_HOSTTYPE"
echo "Over and out."

Add the following task to your pipeline to run the previous script.

- task: ShellScript@2
  inputs:
    scriptPath: 'test.sh'
