While discoverability can be better with GUI's I find that googling things is always better for CLI tools. Most of my CLI search have a one or two lines of bash I can simply copy paste while solutions for GUI programms often involves lot's of screenshots of dropdowns to open and if the look of the application changed or the element's in the dropdown's are not the same it can be hard to follow.

Taking not's of how to do things or creating shorcuts will also always be better with CLI's since manipulation text is easy and always supported.
