Command line and full screen utilities for browsing procfs, a "pseudo" file system dynamically generated by Linux to provide information about the status of entries in its process table.

There exists the possibility that a 'putp' call can be issued before the 'setupterm' invocation has occurred, as is reflected in a bugzilla report referenced below. Strangely, such a SEGV isn't always triggered as logic would suggest it ought to be. I experienced a fault in these environments with the associated curses version: . archlinux, procps-ng 3.3.12, ncurses 6.0.20170429 . fedora-25, procps-ng 3.3.10, ncurses 6.0.20160709 . opensuse-42.2, procps-ng 3.3.9, ncurses 5.9.20140201 . gentoo, procps-ng 3.3.12, ncurses 6.0.20150808 . slackw-14.2, procps-ng 3.3.12, ncurses 6.0.20160910 Whereas under these environments there was no problem: . ubuntu-17.04, procps-ng 3.3.12, ncurses 6.0.20160625 . debian-test, procps-ng 3.3.12, ncurses 6.0.20161126 . mageia-5.1, procps-ng 3.3.9, ncurses 5.9.20140323 [ as an aside, the expected result in the bug report ] [ is incorrect and should mention the '1' parameter. ] [ however, until release 3.3.13 when the '1' becomes ] [ a valid switch, numbers are not detected when used ] [ with any switch which doesn't require an argument. ] [ you're welcome to treat that as a separate bugglet ] Reference(s): https://bugzilla.redhat.com/show_bug.cgi?id=1450429 Signed-off-by: Jim Warner <james.warner@comcast.net> |

procps
procps is a set of command line and full-screen utilities that provide information out of the pseudo-filesystem most commonly located at /proc. This filesystem provides a simple interface to the kernel data structures. The programs of procps generally concentrate on the structures that describe the processess running on the system.
The following programs are found in procps:
- free - Report the amount of free and used memory in the system
- kill - Send a signal to a process based on PID
- pgrep - List processes based on name or other attributes
- pkill - Send a signal to a process based on name or other attributes
- pmap - Report memory map of a process
- ps - Report information of processes
- pwdx - Report current directory of a process
- skill - Obsolete version of pgrep/pkill
- slabtop - Display kernel slab cache information in real time
- snice - Renice a process
- sysctl - Read or Write kernel parameters at run-time
- tload - Graphical representation of system load average
- top - Dynamic real-time view of running processes
- uptime - Display how long the system has been running
- vmstat - Report virtual memory statistics
- w - Report logged in users and what they are doing
- watch - Execute a program periodically, showing output fullscreen
Reporting Bugs
There are a few ways of reporting bugs or feature requests:
- Your distributions bug reporter. If you are using a distribution your first port of call is their bug tracker. This is because each distribution has their own patches and way of dealing with bugs. Also bug reporting often does not need any subscription to websites.
- GitLab Issues - To the left of this page is the issue tracker. You can report bugs here.
- Email list - We have an email list (see below) where you can report bugs. The problem with this method is bug reports often get lost and cannot be tracked. This is especially a big problem when its something that will take time to resolve.
If you need to report bugs, there is more details on the Bug Reporting page.
Email List
The email list for the developers and users of procps is found at http://www.freelists.org/archive/procps/ This email list discusses the development of procps and is used by distributions to also forward or discuss bugs.
