For the Linux 3.11-rc1 release, Linus Torvalds changed the code name from "Unicycling Gorilla" to "Linux for Workgroups" and modified the logo that some systems display when booting to depict a Tux holding a flag with a symbol that is reminiscent of the logo of Windows for Workgroups 3.11, which was released in 1993.
The program produces an ordered list of running processes selected by user-specified criteria, and updates it periodically. Default ordering is by CPU usage, and only the top CPU consumers are shown. top shows how much processing power and memory are being used, as well as other information about the running processes.
The pcregrep command is an implementation of grep that uses Perl regular expression syntax. [17] Similar functionality can be invoked in the GNU version of grep with the -P flag. [18] Ports of grep (within Cygwin and GnuWin32, for example) also run under Microsoft Windows. Some versions of Windows feature the similar qgrep or findstr command. [19]

pstree is a Linux command that shows the running processes as a tree [1] [2] [3]. It is used as a more visual alternative to the ps command. The root of the tree is either init or the process with the given pid. It can also be installed in other Unix systems. In BSD systems, a similar output is created using ps -d, in Linux ps axjf [4] produces ...
VTE is a library (libvte) implementing a terminal emulator widget for GTK, and a minimal sample application (vte) using that. VTE is mainly used in gnome-terminal, but can also be used to embed a console/terminal in games, editors, IDEs, etc. The VTE library provides a terminal emulator widget VteTerminal for applications using the GTK toolkit.
Output of dmesg viewed with grep. The output of dmesg can amount to many complete screens. For this reason, this output is normally reviewed using standard text-manipulation tools such as more, tail, less or grep. [6] Size of the dmesg buffer is limited and the output is often captured in a permanent system logfile via a logging daemon, such as ...
