Hi
Most likely not exactly what you are looking for but I use this. Just tried on my video directory with over 1900 files and almost instantaneous similar to your pipe CLI example.
Directory List (using terminal to create file directory list)
Right Click on folder, then Open in Terminal
ls > name of output file.txt (creates listing in directory)
Note: The > sign above is required as part of command
Example: Right click on Desktop, open in terminal, ls > mydata.txt, creates mydata.txt in Desktop.
There should be something better though. The option of doing hashes to detect duplicate files is one thing I'd like to see, for example, and looking at what the others did, having optional thumbnails is clearly wanted by some.
Given the simple scripts that DO have well supported graphical wrappers, it's still surprising that there isn't one for this though.
There is a bit of a problem there.
Well supported graphical wrappers barely exist for 'bash'
there are two GTK dialogwindows: zenity and yad which are too restricted for this
there are two pretty good full fledged GUI wrappers: gtkdialog and gtkserver but they are unsupported.
'Bash' really could use a good interactive GUI wrapper.
Since Python is a reasonably popular language, it is indeed amazing that a tool like this hasn't been written yet.
I haven't looked at Python yet.
When I come around to learn some Python, I'll probably be fighting with the GUI toolkits.
Are you a bit proficient in Python ?
