You can use bash shell instead of Cisco CLI on Nexus Switches

Every one who works on Linux and understand how to efficiently use Bash hates to work with the limited Cisco IOS CLI. The design objectives standing behind this CLI haven't changed for the last 20 years or so. It is obvious that this tools lacks plenty of features expected from a modern shell for many people.

But the evolution or even revolution that is happening in networking thanks to SDN is changing this terrible static network configuration landscape. The new generation of network devises like Cisco Nexus platform are going to support in the Cisco NX-OS :

• Bash shell
• Python shell 
• API access
• Linux containers for custom applications
