oscmd

Runs commands or scripts supported by the Linux OS directly from the SLX-OS CLI.

Syntax

oscmd { Linux-command | script-name }

Parameters

Linux-command: Specifies the Linux command that you want to run.

script-name: Specifies the script that you want to run.

Modes

Privileged EXEC mode

Usage Guidelines

This command is only available for users with admin-level permissions.

All scripts run under oscmd must have execute permission.

After writing and testing a user-defined script file, you can copy it to the SLX-OS device. Imported scripts are stored in the /var/config/vcs/scripts directory.

You can also create scripts from the Linux shell using the "vi" editor. The newly-created scripts must exist in the /fabos/users/admin directory.

Although as an SLX-OS admin you have permissions to run the following commands from the Linux shell, you do not have permissions to run them—from the SLX-OS CLI—appended to the oscmd command.

bash
script
vi
vim

Examples

In the following example, the Linux ps -ef command lists the process status from the CLI.
