Want to reset NTFS permissions from the command line? Use this syntax:

icacls "c:\users\jshipp\*" /q /c /t /reset

This is the same as using the GUI command:

Win7 - Replace all child object permissions with inheritable permissions from this object
WinXP - Replace permission entries on all child objects with entries shown here that apply to child objects

Warning: If you leave out the * then the jshipp folder will have the same permissions as the users folder, which is not what the GUI does, and probably not what you want, but it's nice to know it's possible.
