Global Operating System Commands
Global operating system commands are standard Linux commands that run on all or specified SGMs. When you run a global command in the gclish shell, the operating system runs a global script, which the standard Linux command on the SGMs. When you run a command in the Expert mode, it works as a standard linux command. To use the global command in the Expert mode, run the global command script version as shown in this table:

The parameters and options for the stand Linux command are available for the global command. In addition, you can use the -b parameter to select some or all SGMs for the global command.
Syntax
{<gclish_command> | <global_command>} [-b <sgm_ids>] <command_options>]
Parameter
|
Description
|
-b <sgm_ids>
|
Works with SGMs and/or Chassis as specified by <sgm_ids>.
The <sgm_ids> can be:
- No <sgm_ids> specified or all shows all SGMs on the Active Chassis
- One SGM
- A comma-separated list of SGMs (1_1,1_4)
- A range of SGMs (1_1-1_4)
- One Chassis (Chassis1 or Chassis2)
- The active Chassis (chassis_active)
Note: You can only select SGMs from one Chassis with this option.

<gclish_command>
|
In the gclish shell, enter the standard command
|
<global_command>
|
In the Expert mode, enter the global command as shown in the table
|
<command_options>
|
Enter the standard command options for the specified command.

Global ls
This example runs the ls command from the Expert mode on SGMs 1_1,1_2, and 1_3. The output shows the combined results for these SGMs.
# g_ls ls –b 1_1-1_3,2_1 /var/
