1. using vim mode in bash terminal: use 'set -o vi' in bottom of .bashrc and source it. Press <Esc> to go to command mode. follow this one
2. To kill processes with a specific keyword in their command line, you can use the pkill command along with the -f option, which allows you to match against the entire command line. In this case, you want to kill processes containing the keyword "/examples/plaquettee". Here's the command:

```bash
pkill -f "/examples/plaquettee"
```

Explanation:

• pkill: The command for sending signals to processes based on their name or other attributes.
• -f: This option tells pkill to match against the entire command line.
• "/examples/plaquettee": The keyword or pattern you want to search for in the command line.

Please be cautious when using pkill, as it can terminate multiple processes that match the specified pattern. Ensure that the pattern you provide is specific enough to target only the processes you intend to terminate.

If you want to see which processes would be matched before actually killing them, you can use the -l (list) option:

```bash
pkill -l -f "/examples/plaquettee"
```

This will list the processes that match the specified pattern without sending any termination signals.
