In UNIX or Linux, the sar command is used to check the run queue. The vmstat UNIX or Linux command can also be used to determine the number of processes that are queued to run or waiting to run. These appear in the 'r' column. Example:
The system utility fsck (file system check) is a tool for checking the consistency of a file system in Unix and Unix-like operating systems, such as Linux, macOS, and FreeBSD. [1] The equivalent programs on MS-DOS and Microsoft Windows are CHKDSK, SFC, and SCANDISK.
In most Unix and Unix-like operating systems, the ps (process status) program displays the currently-running processes. The related Unix utility top provides a real-time view of the running processes.
The Linux "man page" [115] [116] is intended to be the authoritative explanatory technical document for the understanding of how bash operates. It is usually available by running man bash. The GNU manual is sometimes considered more user-friendly for reading.
Although systemd is, as of 2016, used by default in most major Linux distributions, runlevels can still be used through the means provided by the sysvinit project. After the Linux kernel has booted, the /sbin/init program reads the /etc/inittab file to determine the behavior for each runlevel.
In contrast to the previous O(1) scheduler used in older Linux 2.6 kernels, which maintained and switched run queues of active and expired tasks, the CFS scheduler implementation is based on per-CPU run queues, whose nodes are time-ordered schedulable entities that are kept sorted by red–black trees. The CFS does away with the old notion of ...
Also show PID and to which program each socket belongs, e adds extra info like the user. Run as root to see all PIDs. netstat -s: Shows network statistics. netstat -r: Shows kernel routing information. This is the same output as route -e. netstat -i: Displays a table of all network interfaces. Add -e to get output similar to ifconfig. netstat -ct
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.
