19.4.2 Running a Linux script
The Tools→Command Line Tools→Run Script... menu item remotely runs a Linux script in
the Insight Control for Linux repository by opening a secure shell (SSH) connection to one or more
managed systems. This HP Insight Control for Linux tool captures Stdout and Stderr from the
script, captures the return code from the script, and closes the SSH connection.
NOTE: The Run Script... task feeds the command lines in the script to an SSH instance on the
target system. The script is a series of command lines to be run on the target system using SSH.
The Linux script you run must be located in the Insight Control for Linux repository in the /opt/
repository/script directory.
You must ensure that the Linux script does not leave any open file descriptors upon completion
(including scripts you might have called). Open file descriptors can prevent the SSH connection
from closing properly, which might cause the task to remain in a Running state indefinitely.
To run a Linux script on one or more managed systems remotely, follow these steps:
1. Select the following menu item from the HP Insight Control user interface:
Tools→Command Line Tools→Run Script...

• Select Add Targets... or Remove Target to modify the list if the list is incorrect.
3. Select Apply when the list is correct.
