Sloth is a program 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 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 freeware. However, if you enjoy using Sloth and would like to help support its development, please consider making a donation.
