For other shells, like ksh, create command aliases. For example, bash uses printenv while KornShell (ksh) has setenv. This might cause an issue if your target operating system uses a different shell. If you do not publish the output variables, you can still identify which ones you want to be displayed in the deployment details and logs.The Shell Script step uses Bash and PowerShell. When executing a script, you can also dynamically capture the execution output from the script, providing runtime variables based on the script execution context, and export those to another step in the same workflow or another workflow in the same pipeline.įor example, you could use the Shell Script step to capture instance IDs in the deployment environment and then pass those IDs downstream to future workflow steps or phases, or even to other workflows executed in the same pipeline. See PowerShell in Common Profile Scripts. You must install PowerShell on the Delegate using a Delegate Profile. Linux supports PowerShell using PowerShell core. You can run PowerShell scripts on a Harness Delegate, even though the Delegate must be run on Linux. With the Shell Script command, you can execute scripts in the shell session of the Workflow in the following ways: Here's what the YAML should look like when there are no trailing spaces: Remove any trailing spaces from your script to avoid this limitation. Here is what the resulting YAML looks like: For example, this script has a trailing space: If you add a trailing space at the end of any line on your script, Harness YAML transforms that into a single-line value with all control characters visible. This is true for names entered in the Harness Manager UI or YAML via Configure as Code or Git Sync. Shell Script step names cannot contain dots. Secrets Management (for shell session execution credentials).This topic provides a simple demonstration of how to create a bash script in a Shell Script step, publish its output in a variable, and use the published variable in a subsequent Workflow step. Execute bash or PowerShell scripts on a remote target host in the deployment Infrastructure Definition.You can use Delegate Selectors to identify which Harness Delegate to use. Execute bash scripts on the host running a Harness Delegate.With the Shell Script step, you can execute scripts in the shell session of the Workflow in the following ways: One of the steps you can include in a Harness Workflow is a Shell Script step.
