I had 232,000 small text files to delete and they were going to take upward of 50 minutes to push them to the recycle bin by selecting them all and smacking the delete key. I canceled it and tried to shift-delete (delete the files, don't put them in the recycle bin). They were gone in 2-3 seconds.

Warning: When you delete files like this they're gone. The only way to get them back is to run an undelete utility.

SP_PASSWORD @NEW = 'new_password', @loginame = 'sa'

Copying a directory from one system to another is easy:

$ rsync -avz -e ssh directory/ user@systemB:directory/

My first foray into Windows PowerShell hasn't been too painful. It looks a lot like shell scripting and a bit like SQL with the 'where' cmdlets:

PS C:\WINDOWS> ps | where {$_.handles -ge 200 -and $_.name -ne 'svchost'} | sort -Descending handles

If you've got a file open in vim, try the following shortcuts in command mode:
