Problems moving cache

[kitsunisan]

So, after getting root, first thing I did, naturally, was try and move browser/market cache, but I've run into a snag. I came across a thread by Damnitpud listing the move commands, lets take the browser cache as an example:
cd /data/data/com.android.browser/cache
rm -R webviewCache
mkdir /sdcard/cache/webviewCache (if you have already made the cache folder in your microSD)
ln -s /sdcard/webviewCache webviewCache
Pretty straightforward, one would think, but when I get to this step:
cd /data/data/com.android.browser/cache
rm -R webviewCache
I get rm failed for _R, no such file or directory. Don't want to play around with the commands, thought I'd check first here to prevent getting a shiny new brick.
And the market cache failed at the same step, it said permission denied. I was using terminal emulator, since telnet isn't connecting for some reason.
