Hey Mike, I'm not the original poster, but I'm a good candidate to answer since I'm reasonably comfortable with the shell and I've been looking for a tool like Roamer/qmv specifically because of shortcomings in shell renaming (or my knowledge thereof). My most common case for this is renaming a batch of files to a different naming scheme. For example I was recently renaming 15 or so files that were named like "08/30/2017 John Smith 478939da-b172-4952-b428-d77c4f4f6674.doc" and I wanted them all to be named like "john-smith.doc". I did end up renaming them with the shell but through doing something like `for i in *; do { mv $i \`echo $i | tr '[A-Z]' '[a-z]' | tr ' ' '-'\` } done` (I don't have the final script anymore). Which is slower to write and less elegant than the Roamer/qmv approach. But I'm very curious if there's a better approach to this problem on the shell.
