==Introduction==

[https://www.freebsd.org/cgi/man.cgi?query=rc&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html '''rc''']  is a	command	interpreter and	programming language similar to	[https://www.freebsd.org/cgi/man.cgi?query=sh&sektion=1&apropos=0&manpath=FreeBSD+12.1-RELEASE+and+Ports '''sh(1)''']. It is based on the AT&T Plan 9 shell of the same	name.  The  shell  offers  a	C-like	syntax (much more so than the Cshell) and a powerful mechanism for manipulating variables.  It is reasonably small and  reasonably fast, especially when compared to contemporary shells.  Its use is intended to be interactive, but the language lends  itself  well  to scripts.<br/>
[https://www.freebsd.org/cgi/man.cgi?query=rc&apropos=0&sektion=0&manpath=FreeBSD+12.1-RELEASE+and+Ports&arch=default&format=html '''rc'''] is the base of all scripts and files related to '''[[OpenRC]]'''.

==SYNOPSIS==

Syntax: rc [Option] [-c command] [arguments]
       
There are options with this letters: [-deiIlnopsvx] 

If  -c  is  present,  commands are executed from the immediately  following	argument.  Any further arguments to rc are  placed  in $*.  Thus:

<code> rc -c 'echo $*' 1 2 3</code><br/>
prints out:  1 2 3

==COMMANDS==

A  simple  command  is  a  sequence  of words, separated	by white space (space and tab) characters that ends with a newline, semicolon (;),  or  ampersand  (&). The  first word of a command is the name of that command.  If the name begins with /, ./, or	../, then the name is used  as an  absolute path name referring	to an executable file.	Otherwise, the name of the command is looked up	in a table of shell functions, builtin  commands, or as a file in the directories named by $path.
