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.

A recent issue (and merge request) reminded me of gaps in top's alternate 'vim' navigation keys support. Some xterm emulators do not pass the customary strings when keys were used with the <Ctrl> and/or <Alt> modifiers. While it was a known problem, this issue/merge request prompted research into the root cause. As it turns out the problem is traceable to an X resource known by the name 'eightBitInput'. When 'true' (the default), a key pressed in combination with <Alt> will not be preceded by the <Esc> character. Rather, a single character was presented (modified via an 'eightBitMeta' X resource). The following approaches would eliminate this problem: . start xterm thus: xterm -xrm '*eightBitInput: false' . use: ~/.Xresources with 'Xterm*eightBitInput: false' . build xterm with 'configure --enable-meta-sends-esc' ( apparently used for CentOS, Fedora, openSUSE, etc. ) . enable xterm's menu via 'configure --enable-toolbar' ( so the user can set the 'Meta Sends Escape' option ) Of course, none of the above steps is desirable from a user's perspective. So, this patch will add additional entries to the iokey function's tinfo_tab to represent strings passed when the <Alt> key does not send <Esc>. [ hopefully they'll be the same across all platforms ] Lastly, this patch will also eliminate those redundant <Atl> + '\', '/', '<' & '>' provisions, which now seem like overkill and suffer from that same 'eightBitMeta' xterm problem. And we might as well say goodbye to the 4 '<Alt> + arrow key' table entries (which do not seem to currently work with any emulator which I can find). [ what in the world was I thinking way back in 2011? ] Reference(s): . issue https://gitlab.com/procps-ng/procps/issues/135 . merge request https://gitlab.com/procps-ng/procps/merge_requests/84 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.
