Logcat File?

I have been searching around but haven't found the answer. I have got logcat working but I haven't figured out how to make a logcat file to look through on my computer. I found a post that said to type: adb shell logcat > /logcat but the screen just sits there without anything ever happening.

I think it would also be helful for someone to write up a good tutorial on how they use logcat to figure out problems with there phone so people can do more than just come into the rom forums and say they are getting a force close on this app or there is a lot of lag. Those don't help much in figuring out if it is a problem with the rom, the app, or some old apps hanging around causing trouble and time for a wipe.

Yes that is what I am getting now but I want to output that to a file.

Someone should be able to answer this question for me.

What am I doing wrong?

I answered my own question.
You type:
adb logcat > logcat.txt
Then the command prompt screen doesn't appear to be doing anything but it is writing everything to the logcat.txt file which is in the SDK tools folder that you are running the logcat file from.

Now my question is, is it normal to get this Low memory warning. I wouldn't think it would be but I don't know for sure. I do see some background applications that I can get rid of permanantly but is there anything else I can do or I can look for to prevent this. Also to exit the logcat I have just been unplugging the usb cord from the phone, is there some other way to end the command?
