Script(3.0)
The Script Agent is used in task workflows, and is used for executing system housekeeping task such as removing files or cleaning up database tables.
This agent runs a shell script or other executable located on the filesystem of an EC. The workflow will stop when it receives an exit code from the script. If the script returns a non-zero exit code, the workflow will abort. Output to stdout will appear in the debug output from the agent.
| Setting | Description |
|---|---|
Script Name | Enter the absolute path and name of the script file or executable that will perform the task. You may omit the path if it is not required by the shell. For instance, to remove files or directories you can simply enter |
Parameters | Enter the arguments and options expected by the script. The value will be passed as-is to the shell, except for carriage return characters, which will be handled as a blank spaces. To call the script without options parameters, leave this field blank. |
Warning!
It is strongly recommended that you run script task workflows on a separate EC. Running script task workflows on the same EC as other workflows may cause unpredictable errors and loss of data.
During a short time before exec() runs the actual script, fork() allocates the same amount of memory for the script as used for the EC. If the memory is not available, the EC will abort with an out of memory error and must then be restarted.
