Sloth is a Mac OS X application that displays a list of all open files in use by all the applications your user account is running on the system -- this list includes IP and Unix sockets, character devices and directories, and is generated via the powerful lsof command line tool. This list is presented along with the names of applications using the file and their process IDs. Sloth thus makes it easy to find out which applications are using which files. Includes support for regex list filtering, process killing, sorting and more.

Sloth is written in Objective C and written for Apple's Cocoa APIs. Sloth is free, open source software and is distributed under the terms and conditions of the Free Software Foundation's GNU General Public License.

The latest version is Sloth 1.5. It works on Mac OS X 10.4 or later and is a Universal Binary.
