I want to know about cisco nxos vsh.bin

[ggnogame1]

Hello, I'm leaving a post on the community because of the questions below.
If you run the cisco nexus 9000 series, you can see the following accounting log.

Sat Oct 5 01:39:06 2024:type=start:id=vsh.bin.10027:user=admin:cmd=
Sat Oct 5 01:39:06 2024:type=update:id=vsh.bin.10027:user=admin:cmd=configure terminal ; interface mgmt0 (SUCCESS)

May I know what vsh.bin is here, and how it works in NXOS?

Thank you.

Hello @ggnogame1 

The vsh.bin process process in Nexus 9000 series switches represents the Virtual Shell and is primarily used to run NX-OS CLI commands from the Bash shell. It acts as a gateway, allowing the execution of NX-OS commands within the Linux-based environment of the Nexus platform.

Hello M02@rt37, thank you for your quick and detailed reply!
I have one more question about this.

If so, can I understand that this vsh.bin works by approaching the Bash shell?
In other words, if certain commands are executed in the Bash Shell after the feature bash/run bash, will it be recorded in the accounting log of the NXOS?

Thank you!

I am not aware that the command used in the bash shell will be shown in Nexus OS Log as accounting logs.

But in general, you can view a Unix/Linux command as a history command in the shell if that is supported.
