Does any one know of a good, free, visual SVN client for Linux?
I've used Subcommander, which worked quite well, although nowadays I usually use Subclipse from within Eclipse along with the command-line.
KDESVN A feature-rich client with great history and revision views, annotated code views showing who changed each line of code and when it was changed, and 3D graphical views of branching and merging among trees. Written in C++ with Qt, but using KDE libraries (which are somewhat troublesome to get on Windows).
RabbitVCS A Python extension to integrate Subversion functionality into the Nautilus File Manager, basically as a clone of the TortoiseSVN project on Windows. —Wikipedia
If you consider vim to be visual, then you can get the vcscommand plugin.
Seen a bunch. Officially declare: command line is waaay more effective, and naturally integrates with other GNU utilities. Learn the command line! :) It's free, visual, and very good. And it's simpler than it seems.
And then there's Emacs ;-) Has a number of "visual" clients, or rather, a number of solutions for integrating SVN (and git, hg, bzr, cvs even...).
