using rsync to copy files and folders

Quest for a tool to do a copy excluding hidden files lead me to find the rsync command. Here is how I copy a folder from source to destination excluding all hidden files/folders (all that with a "." prefix in the name).

rsync -a --exclude='.*' source/ destination/

This might be especially useful when copying folders checked out from SVN, that needs to be checked-in to a different location. Having the .svn folder under sub-folders can cause them not to be checked in.

vim 101 : tip 1

Normally I use vim with multiple splits and tabs. Once I quit vim, I have to open them up all again, and remember which file (and the location in the file) I was editing before I quit.

Here is trick:
Before quitting vim, just run ":mksession" (if you have multiple tabs open, then in just one of them). And then quit.

Next time you are in the same folder, and want to open the same session just run the command "gvim -S"

The contexts are stored in session.vim. So if you want to overwrite it at some later point of time run the command with an override ":mksession!"
