Jim Warner 49bb9f9ae4 top: add variable width data display without scrolling <=== port of newlib fb32021e
______________________________ original newlib message

There are times when one might want to see some task's
particular variable width data. However, prior to this
commit, the only way was to first turn on a field then
scroll through it via repeated right arrow keystrokes.

[ this also required that field to be displayed last ]

Needless to say, given the potential length of some of
that variable data this could be extremely cumbersome.

Now with this patch, a Ctrl keystroke combination will
create a separate window at the bottom of the terminal
screen where such variable width data is seen in full.

[ the targeted task is the 1st task displayed, which ]
[ is a convention employed in some existing commands ]

[ the targeted data was determined by these Ctrl key ]
[ combinations: CtrlG = ctrl group; CtrlK = cmdline; ]
[ CtrlU = supplementary groups; plus CtrlV = environ ]

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:

  1. 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.
  2. GitLab Issues - To the left of this page is the issue tracker. You can report bugs here.
  3. 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.
