Nutanix is the number #1 hyper converged HCI solution in the world and growing as market leader in Hyper converged technology and Xi-cloud as well. Nutanix HCI management has multi-interface like HTML5, acli, ncli and REST API for troubleshooting, manage and execute daily or one time configuration task(s).
Nutanix native build many management interfaces to manage Nutanix Hyper HCI infrastructure.
Nutanix Command Line Interfaces
Nutanix acropolis supports two commands frameworks acli and ncli
What is Nutanix acli Command
Nutanix acli stands for Acropolis Command Line Interface (acli) to manage nutanix cluster daily task(s) related to host, network, VM’s snapshots and VMs.
- Nutanix acli give extra core commands access to manage Nutanix AHV host, networking, manual snapshots and VMs related commands
- Nuanix acli framework doesn’t have access to call ncli commands
- Through acli commands can’t manage Nutanix cluster functions
- Nutanix acli has only 20-30% commands of Nutanix cluster for management.
- Nutanix acli doesn’t contains hidden commands
Nutanix acli sub-command example:
- ads
- core
- ha
- host
- image
- iscsi_client
- microseg
- net
- nf
- parcel
- snapshot
- task
- vg
- vm
- vm_group
Warning : Before run any Nutanix acli command in Nutanix CVM make sure you must have good understanding of that command otherwise wrong command(s) may impact on running VMs production.
What is Nutanix ncli Command
Nutanix ncli stands for Nutanix Command Line Interface (ncli) to manage Nutanix cluster complex task(s) and get detailed cluster information.
Nutanix administrator can run 70-80% commands through ncli to mange Nutanix cluster.
- Nutanix ncli container advance entities command to manage nutanix cluster
- Nutanix ncli contains hidden commands and appear to run ncli -h true command
- Through Nutanix ncli command administrator can manage almost entire Nutanix AHV cluster
- Nutanix ncli command is more powerful and complex to run in comparison of acli
- Nutanix ncli command(s) must be run if you have good understanding of ncli entities and commands
- Nutanix ncli is the alternate option to mange cluster without accessing Nutanix Prism

How to clean ncli Command History
Nutanix ncli history is stored locally on each node in the file
/home/nutanix/.nutanix_history
You can edit this file and remove the lines you don’t want to appear, or delete it to clear the whole history.
To clear ncli history on all the nodes, run:
allssh 'rm ~/.nutanix_history'
Warning : Before run any Nutanix ncli command in Nutanix CVM make sure you must have good understanding of that command otherwise wrong command may impact on Nutanix cluster and running VMS production.

Conclusion
Nutanix provide command line interface for troubleshooting and execute commands to accomplish the task if having good understanding of Nutanix framework acli and nclil commands.
It is advised by Nutanix to run Nutanix command framework by Nutanix support engineer (SRE) and Nutanix administrators only.
I hope this blog will give you better understanding about Nutanix command line framework and difference between Nutanix acli and ncli.
