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 standard 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>.
<sgm_ids> can be:
- No <sgm_ids> specified or
all shows all SGMs and 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>
|
Standard command in gclish
|
<global_command>
|
Global command as shown in the table, in Expert Mode
|
<command_options>
|
Standard command options for the specified command.

You can use one or more flags. However, do not use the –l and –r flags together.

Global ls
This example runs ls from 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/
