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.

When that 'Bottom' window was being finalized, an enum of BREAK_screen was added to the Frames_signal values. This was done so some full screen replacement function could flag the need for that bottom window to go away. Around that same time, top was made more responsive to keyboard input so that residual portions of a previous bottom window would not linger until the next refresh. This happened if going from a larger (^N, environment) bottom window to some smaller window (^P, namespaces). The combined effect of these changes was to create the potential race condition this commit addresses. If the user encountered a SIGWINCH while on any of those full screen replacement displays (help, fields mgmt, etc.), endless redraws would occur. A ^C was the only option. Henceforth we will protect against any redraw loops by clearing Frames_signal each time a redraw is required. [ along the way, we'll make the 'q' key work on that ] t secondary 'windows' help screen as it should, even ] [ though it is not documented on that screen itself. ] Reference(s): . May, 2022 - more responsive to keyboard input commit |

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 distribution's 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.
