ClipLog, the clipboard logger! The first bloat-free clipboard manager!
ClipLog is a lightweight application which logs all text you send to clipboard (aka pasteboard) in a plain text file. It's clean, it's lightweight, it's unobtrusive.
No fancy keystrokes to learn, neither lots of preferences.
Just a good 'n old plain text file, filled with all text content you cut or copy by traditional ways.
Now you can use 'grep' on your clipboard :)
