Unlike operating directly in MD-CLI, the NISH MD-CLI provides a hybrid shell that allows users to execute Linux commands directly on the local workstation, without leaving the MD-CLI shell. This provides a flexible working environment for managing multiple nodes.
The following example shows output of a configure system setup, with execution of both Linux and MD-CLI commands:
(pr)[configure system]
A:admin@test1# ls -la

If a command exists in both the MD-CLI and the Linux shell, the MD-CLI command takes precedence. This is shown in the following output example, which uses the time command:
(pr)[configure system]
A:admin@test1# time echo ‟hello world”
^^^^
MINOR: MGMT_CORE #2201: Unknown element - 'echo'
(pr)[configure system]
A:admin@test1# time
(pr)[configure system time]
A:admin@test1# time echo ‟hello world”
"hello world"
