Chapter 4. Using the command-line assistant powered by RHEL Lightspeed on RHEL systems

To use the command-line assistant powered by RHEL Lightspeed, use the “c” command followed by your questions in quotation marks. For example:

The following are examples of prompts that you can use to interact with the command-line assistant when using your RHEL systems:

Request information on how to troubleshooting a problem:

c "how to troubleshoot sshd failing to start"

$ c "how to troubleshoot sshd failing to start"

c "how do I find all the files in the /etc that have been modified in the last hour"

$ c "how do I find all the files in the /etc that have been modified in the last hour"

You can attach a file to the command-line assistant powered by RHEL Lightspeed. By doing so, the assistant can provide a tailored response based on that file.

For example, if you want to replicate the volume group, logical volumes, and file systems on another system, you can create a file with the storage information, and run the command-line assistant to get information about the required steps to replicate that specific storage partition in another system. For example:

c --attachment <storage_info>

$ c --attachment <storage_info>

Optionally, use the short version of the attachment command. For example:

c -a <storage_info>

$ c -a <storage_info>

You can also combine the attachment with a question:

c --attachment <storage_info> "how can I replicate the storage configuration in another system"

$ c --attachment <storage_info> "how can I replicate the storage configuration in another system"

Access your conversation history with the command-line assistant powered by RHEL Lightspeed.

Use the log file that contains information that you want to understand by redirecting that log file output to command-line assistant powered by RHEL Lightspeed.

cat <log_file.log> | c

$ cat <log_file.log> | c

If the error or log that you have provided to the command-line assistant does not provide enough information, you can combine the redirect output with a question, for example:

cat <log_file_error.log> | c "how do I solve this?"

$ cat <log_file_error.log> | c "how do I solve this?"

You can also redirect a question:

echo "how do I solve this?" | c -a <log_file_error.log>"

$ echo "how do I solve this?" | c -a <log_file_error.log>"

The command-line assistant powered by RHEL Lightspeed has an optional feature that enables you to reference commands that you previously ran.

You can submit feedback about the responses that you receive when you interact with the command-line assistant powered by RHEL Lightspeed:

$ c feedback
