psmisc Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies
  4. psmisc-23.3.tar.xz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

Coverity Scan Build Status


A package of small utilities that use the proc file-system.

  • fuser - Identifies processes using files or sockets
  • killall - kills processes by name, e.g. killall -HUP named
  • prtstat - prints statistics of a process
  • pslog - prints log path(s) of a process
  • pstree - shows the currently running processes as a tree
  • peekfd - shows the data travelling over a file descriptor

psmisc is now hosted on gitlab at for bugs or issues please use the issue tracker at

Email List

No email list as such, but there is a Gitter room found at This is an experimental trial of how Gitter works with a Gitlab project such as psmisc but its better than no email list.

fuser on network fs

On network file-systems, fuser can hang because its trying to stat files that may go away. If you use the --with-timeout-stat option during the configure step then fuser will fork a process to run stat. This means fuser doesn't hang, but it is much slower.



My thanks for the various translators who have cheerfully given me the po files to make psmisc speak different languages. If your language is not supported then let me know, all it takes is translating one file in a certain manner.
