|-
|[||The [https://www.freebsd.org/cgi/man.cgi?query=test&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&format=html test] utility evaluates	the expression and, if it evaluates to true,    returns a zero (true) exit	status;	otherwise it returns 1 (false).	 If  there is no expression, test also returns 1 (false).
|-
|cat||The [https://www.freebsd.org/cgi/man.cgi?query=cat&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&arch=default&format=html cat] utility reads files sequentially, writing them to the standard output.  The file operands	are processed in command-line order.  If file is	a single dash (`-') or absent, cat reads from the standard input.  If file is a UNIX domain socket, cat connects	to it and then reads it	until EOF.  This	complements the	UNIX domain binding capability available in [https://www.freebsd.org/cgi/man.cgi?query=inetd&sektion=8&apropos=0&manpath=FreeBSD+7.2-RELEASE inetd(8)].
|-
|chflags|| The [https://www.freebsd.org/cgi/man.cgi?query=chflags&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&arch=default&format=html chflags] utility modifies the file flags of the	listed files as	specified by the flags operand.
|-
|chio||The [https://www.freebsd.org/cgi/man.cgi?query=chio&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&arch=default&format=html chio] utility is used to control the operation of medium changers, such as those found in tape and optical disk jukeboxes.
|-
|chmod||The [https://www.freebsd.org/cgi/man.cgi?query=chmod&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&arch=default&format=html chmod] utility modifies	the file mode bits of the listed files as specified by the ''mode'' operand.
|-
|cp||In	the first synopsis form, the [https://www.freebsd.org/cgi/man.cgi?query=cp&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&arch=default&format=html cp] utility	copies the contents of the source_file to the	target_file.  In the second synopsis form, the contents of each named source_file is	copied to the destination target_directory.	The names of the files themselves are not changed.  If cp	detects	an attempt to copy a file to itself, the copy will fail.
|-
|csh||[https://www.freebsd.org/cgi/man.cgi?query=csh&sektion=1&apropos=0&manpath=FreeBSD+7.2-RELEASE C	shell]
|-

|dd||The [https://www.freebsd.org/cgi/man.cgi?query=dd&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&arch=default&format=html dd] utility copies the standard	input to the standard output.  Input data is read and written in 512-byte blocks.  If input reads are short, input from	multiple reads are aggregated to form the output block.	 When finished, dd displays the number of complete and partial input and	output blocks and	truncated input	records	to the standard	error output.

|-
|df||The [https://www.freebsd.org/cgi/man.cgi?query=df&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&arch=default&format=html df] utility displays statistics	about the amount of free disk space on the specified file	system or on the file system of	which file is a	part. Values are	displayed in 512-byte per block	counts.	 
|-
|domainname||The [https://www.freebsd.org/cgi/man.cgi?query=domainname&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&arch=default&format=html domainname] utility prints the name of the current YP/NIS domain.  The      super-user	can set	the domain name	by supplying an	argument; this is usually done in the network initialization script /etc/rc.network, normally run at boot time.

|-
|echo||  The [https://www.freebsd.org/cgi/man.cgi?query=echo&apropos=0&sektion=0&manpath=FreeBSD+7.2-RELEASE&arch=default&format=html echo] utility writes any specified operands, separated by single blank (` ') characters and followed by a	newline	(`\n') character, to the standard output.

|-
|getfacl||The [https://www.freebsd.org/cgi/man.cgi?query=getfacl&sektion=1 getfacl] utility writes	discretionary access control information associated with the specified file(s) to standard output.
|-
|hostname||The [https://www.freebsd.org/cgi/man.cgi?query=hostname&apropos=0&sektion=1&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html hostname] utility prints the name of the current host.	The super-user      can set the hostname by supplying an argument; this is usually done in      the initialization	''script /etc/rc.d/hostname'', normally run	at boot	time. This script uses the hostname variable in ''/etc/rc.conf''.
|-
|[[kenv]]||The [https://www.freebsd.org/cgi/man.cgi?query=kenv&apropos=0&sektion=1&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html kenv] utility will dump	the kernel environment if invoked without arguments.  If the '''-h''' option	is specified, it will limit the	report to kernel probe hints.  If an optional variable name is specified, kenv will only report that value.  If the '''-N''' option is specified, kenv will only  display variable names and	not their values.  If the '''-u''' option is specified, kenv	will delete the	given environment variable.  If	the environment variable is followed by an optional value, kenv will set the environment variable to this value.
|-
|kill||The [https://www.freebsd.org/cgi/man.cgi?query=kill&apropos=0&sektion=1&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html kill] utility sends a signal to	the processes specified	by the pid operands. Only the super-user may send signals to other users' processes.

For each operand that names a file	of a type other	than directory,	ls displays its name as well as any requested, associated information.  For  each operand that names a file of type directory, ls displays the names
of	files contained	within that directory, as well as any requested, associated information.
|-
|mkdir||[https://www.freebsd.org/cgi/man.cgi?query=mkdir&apropos=0&sektion=1&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html mkdir]: make directories;  The mkdir utility creates the directories named as operands, in the order specified,	using mode "rwxrwxrwx" (0777) as modified by the current [https://www.freebsd.org/cgi/man.cgi?query=umask&sektion=2&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports umask(2)].

These operations are independent of the specific archive format, and support a	wide variety of	different archive formats.  A	list of	supported archive formats can be found under the description of the '''-x''' option.
|-
|pgrep||The [https://www.freebsd.org/cgi/man.cgi?query=pgrep&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html pgrep] command searches	the process table on the running system	and      prints the	process	IDs of all processes that match	the criteria given on      the command line.

|-
|pwd||The [https://www.freebsd.org/cgi/man.cgi?query=pwd&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html pwd] utility writes the	absolute pathname of the current working directory to	the standard output.
|-
|[[rc-status]]||TrueOS has been using OpenRC successfully for many years in base and ports.
The goal is to integrate OpenRC into the FreeBSD RC system, allowing either
RC system or OpenRC to be chosen at boot, and OpenRC ports RC scripts for the
entire ports tree. As for now the plan is to get this into the base, and
bring these to ports in the second step. [https://reviews.freebsd.org/D18578 see: Revision Contents] [https://docs.huihoo.com/puppet/references/3.0.1/type.html OpenRC] initskripts uses [[rc-update]], [[rc-status]] and rc-service to manage services.

|-
|red||The [https://www.freebsd.org/cgi/man.cgi?query=red&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html ed] utility is a line-oriented text editor. It	is used	to create,  display, modify and otherwise manipulate text files.  When	invoked	as red, the editor runs in "restricted" mode,	in which the only difference is	that the editor	restricts the use of filenames which start with	`!' (interpreted as shell commands by ed) or contain a	`/'. 
|-
|rm|| The [https://www.freebsd.org/cgi/man.cgi?query=rm&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html rm] utility attempts to	remove the non-directory type files specified on	the command line.  If the permissions of the file do not permit	writing, and the standard input device	is a terminal, the user	is prompted (on the standard error output) for	confirmation.
|-
|rmail||[https://www.freebsd.org/cgi/man.cgi?query=rmail&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html Postfix to Sendmail compatibility interface]

|-
|tcsh||[https://www.freebsd.org/cgi/man.cgi?query=tcsh&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html C	shell] with file	name completion	and command line editing
