Sure, GUI tools have crept in here and there. And I understand that some toolchains mandate all-singing, all-dancing IDEs. I don't work in those areas (the closest I've come was doing Java work for about five years and I still lived in vi, because Eclipse makes me homicidal). And I still see our iOS developers using `find' and `sed'.
Which isn't to say GUIs can't improve on the command line for some things. For example, the MacOS tool "A Better Finder Rename" (despite its inability to rename itself something less clunky) is a great tool for mass-renaming, e.g., photos. I have written such critters before as shell/perl/python scripts, but pulling EXIF data and renaming files programmatically is ticky and potentially destructive enough that I tend to write it once and then not modify it unless it breaks. The GUI preview and regex capture display makes this much less annoying.
