It allows users to run programs which require a command-line interface. If no particular program is specified, xterm runs the user's shell. An X display can show one or more user's xterm windows output at the same time. [2] [3] Each xterm window is a separate process, but all share the same keyboard, taking turns as each xterm process acquires ...
nice is a program found on Unix and Unix-like operating systems such as Linux.It directly maps to a kernel call of the same name. nice is used to invoke a utility or shell script with a particular CPU priority, thus giving the process more or less CPU time than other processes.
The client starts the protocol by connecting to the session manager. How the session manager is located on the network is system-dependent: in a POSIX system, the environment contains a variable SESSION_MANAGER. Therefore, when a client is launched, its environment must contain this variable with an appropriate value.
chattr, the command used to change the attributes of a file or directory on Linux systems; chown, the command used to change the owner of a file or directory on Unix-like systems; chgrp, the command used to change the group of a file or directory on Unix-like systems
Expect is an extension to the Tcl scripting language written by Don Libes. [2] The program automates interactions with programs that expose a text terminal interface. Expect, originally written in 1990 for the Unix platform, has since become available for Microsoft Windows and other systems.
After the Linux kernel has booted, the /sbin/init program reads the /etc/inittab file to determine the behavior for each runlevel. Unless the user specifies another value as a kernel boot parameter, the system will attempt to enter (start) the default runlevel.
In modern computers many processes run at once. Active processes are placed in an array called a run queue, or runqueue. The run queue may contain priority values for each process, which will be used by the scheduler to determine which process to run next. To ensure each program has a fair share of resources, each one is run for some time ...
A desktop session is all the windows currently running and their current content. Session management on Linux-based systems is provided by X session manager. On Microsoft Windows systems, session management is provided by the Session Manager Subsystem (smss.exe); user session functionality can be extended by third-party applications like twinsplay.
