Me again! Last time I was here, I asked if there was a good command-line-based file management program, so that I could move and delete and rename files without having to type in cd and rm and ls all the time, and you guys reccomended Midnight Commander (mc), which works GREAT and was exactly what I was looking for!
Well now I'm looking for a program like Midnight Commander that also shows the total size of all the files in a folder, similar to how JAM Software's TreeSize works on Windows. But it has to be command-line based, because this is all running on my OpenWRT router, which has no display, only SSH and WebUI access.
If there isn't something as fancy and nice as MC, maybe just a simple command I can type to find out the total size of all the files in a folder, like how I can right click on a folder in Windows and click properties to find its size? Because my router also has a USB HD NAS, and it's getting pretty cluttered and full, and it would be nice to be able to know which folders I should start deleting without having to guess, or add up the total file sizes, or unplug the hard drive and plug it into my other Linux PC (its EXT4) for running TreeSize.
