| Usage: |
| # Running the CLI in interactive mode: |
| $ ./onoscli |
| |
| # Running multiple CLI commands in batch mode |
| $ cat commands.txt | ./onoscli |
| |
| # Running a single command from the system command-line |
| $ ./onoscli -c show switch all |
| |
| # Run the following command for additional help |
| $ ./onoscli -h |
| """ |

| # INSTALLATION NOTES: MUST install Python cmd2 module. E.g., on Ubuntu: |
| # sudo apt-get install python-cmd2 |
| # On older Ubuntu installations (e.g., Ubuntu-12.04), install also: |
| # sudo apt-get install python-pyparsing |
| # |
| |
| # |
| # ADDING A NEW CLI COMMAND: |
| # 1. Add the appropriate Command entry (or entries) inside array |
| # OnosCli.init_commands. |
| # See the comments for init_commands for details. |
| # 2. Add the appropriate callback (inside class OnosCli) for the CLI command |
