Jim Warner 0d386260b4 library: let's make 'escaped_copy' multibyte aware too
This patch is intended to bring the master branch into
closer alignment with the newlib branch functionality.

The commit shown below replaced that 'escape_str' with
'escaped_copy' so that the ps program wouldn't execute
some code twice. However, it created a problem for the
top program when the UTF-8 encoding was not available.

Unlike ps who calls the escape functions directly, top
outputs those library provided strings unaltered. That
means there is no workaround (like LANG=) when such an
encoding was unavailable. This, in turn, can lead to a
corrupted display (especially with the linux console).

Now, when a UTF-8 encoding is not available, multibyte
chars are converted to '?', reducing display problems.

[ there's still a potential problem concerning 'cmd' ]
[ should program names contain multibyte characters. ]
[ unlike that newlib branch, this string is not ever ]
[ altered with the '?' char under the master branch. ]

Reference(s);
. Dec 2020, escaoed_copy repleced most escape_str

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.
