Thanks a lot for this list of Linux software.
Yesterday, using probably the wrong application, I was taking hours to sync two folders, then after reading here I learned about FreeFileSync, that finished the job in a few minutes, awesome.

By the way, I see that Truecrypt is still listed, with a link pointing to http://www[dot]truecrypt[dot]org/downloads [Mod: bad link obfuscated], which is currently considered suspicious. Looking for alternatives, so far I tried tcplay, not very user friendly being text only, but it works well with Truecrypt archives.
