Bash Completion with ChatGPT

Let chatGPT review your bash history and propose your next command to run.

One of the things I love of the bash command line is the ability to write a few letters of a comand, press twice “tab” and get bash write the rest of the command including parameters for me. This is made possible by the integration in the shell of program named complete.

I wanted to push the envelope and get the prompt to propose to me the next command I should run. For this, I would call chatGPT using the history of commands ran so far, the previous AI suggestions and the commands that I have actually ran.

Each time that bash shows me the prompt PS1, my script would show a line above with the suggested command to run next.

I changed my prompt to this:

And added two aliases to enable or disable the AI suggestions.

I edited the scenario file used by askGPT, a program I wrote to interact with ChatGPT from the command line. I added a few lines of my bash history, as well as a sample of the AI suggestion and the actual command that the user ran.

I opened a new terminal and as I wrote commands I got the suggestions from askGPT.

Till the next hack.
