opcontrol is used to start and stop the daemon, which collects profiling data. This data is periodically saved to the /var/lib/oprofile/samples directory. opreport shows basic profiling data. opannotate can produce annotated sources or assembly. opgprof converts from oprofile data into gprof-compatible format. [4] Example:
It also includes the programs such as update-alternatives and start-stop-daemon. The install-info program used to be included as well, but was later removed [7] as it is now developed and distributed separately. [8] The Debian package "dpkg-dev" includes the numerous build tools described below.
Components of some Linux desktop environments that are daemons include D-Bus, NetworkManager (here called unetwork), PulseAudio (usound), and Avahi.. In multitasking computer operating systems, a daemon (/ ˈ d iː m ən / or / ˈ d eɪ m ən /) [1] is a computer program that runs as a background process, rather than being under the direct control of an interactive user.
In Windows NT operating systems, a Windows service is a computer program that operates in the background. [1] It is similar in concept to a Unix daemon. [1] A Windows service must conform to the interface rules and protocols of the Service Control Manager, the component responsible for managing Windows services.
In a Linux system, for example, the watchdog daemon could attempt to perform a software-initiated restart, which can be preferable to a hardware reset as the file systems will be safely unmounted and fault information will be logged. It is essential, however, to have the insurance provided by a hardware timer, since a software restart can fail ...
On a Windows system, a background process is either a computer program that does not create a user interface, or a Windows service. The former are started just as any other program is started, e.g., via Start menu. Windows services, on the other hand, are started by Service Control Manager.
Ctrl-C (in older Unixes, DEL) sends an INT signal ("interrupt", SIGINT); by default, this causes the process to terminate. Ctrl-Z sends a TSTP signal ("terminal stop", SIGTSTP); by default, this causes the process to suspend execution. [4] Ctrl-\ sends a QUIT signal ; by default, this causes the process to terminate and dump core.
A terminate-and-stay-resident program (commonly TSR) is a computer program running under DOS that uses a system call to return control to DOS as though it has finished, but remains in computer memory so it can be reactivated later. [1] This technique partially overcame DOS's limitation of executing only one program, or task, at a time.
