linux rc ist die Abkürzung für runcom und ist auch das rc, das in „.cshrc“ oder „/etc/rc“ vorkommt. rc stammt von runcom, das in einigen Szenarien erstmals im MIT CTSS-System auftauchte. Das ausgeführte System wird ausgeführt. Mehrere in Dateien gespeicherte Befehle werden als Runcom bezeichnet, was die Abkürzung für Ausführungsbefehle ist.
Die Betriebsumgebung dieses Tutorials: Linux5.9.8-System, Dell G3-Computer.
linux rc Was bedeutet das?
Linux rc volle Bedeutung
Dies beginnt mit der prähistorischen Ära des Unix-Systems (1961-1969). Time-Sharing-System (kompatibles Time-Sharing-System), auch CTSS genannt. (Obwohl die Funktionen dieses CTSS nicht so gut sind wie die späterer Unix-Systeme, sind sie immer älter.) Es gibt eine Funktion zu Befehlsskripten im CTSS-System namens runcom. runcom。 为了致敬这个古早版本Unix系统——CTSS的runcom特性，后来的Unix系统中就用rc作为操作系统的启动文件名。
在某些场景中，(我们)会执行被存储在文件中的多条命令commands，我们称之为runcom即运行命令run commands的简称。 另外，这个用于存储命令的文件被称作：a runcom。 Unix文件命名中的rc就是来自于这样的老典故。 — Brian Kernighan & Dennis Ritchie, as told to Vicki Brown
Also ESR states that in Run-Control Files: 当然，你也可以在 Run-Control文件中找到证据： rc后缀一直往前追溯，会发现其实它在Unix的爷爷辈老系统——CTSS里就有了。 而在CTSS这个古早的系统中有一个命令脚本的特性叫做：runcom。 于是早期Unix就开始使用rc作为操作系统启动脚本的文件名，以此来追忆/致敬 CTSS runcom。
所以我认为：rc是runcom Um der Runcom-Funktion von CTSS, einer frühen Version des Unix-Systems, Tribut zu zollen, wurde rc in späteren Unix-Systemen als Startdateiname des Betriebssystems verwendet.

1.3) What does {some strange unix command name} stand for?
awk = "Aho Weinberger and Kernighan"
This language was named by its authors, Al Aho, Peter
Weinberger and Brian Kernighan.
grep = "Global Regular Expression Print"
grep comes from the ed command to print all lines matching a
certain pattern
g/re/p
where "re" is a "regular expression".
fgrep = "Fixed GREP".
fgrep searches for fixed strings only. The "f" does not stand
for "fast" - in fact, "fgrep foobar *.c" is usually slower than
"egrep foobar *.c" (Yes, this is kind of surprising. Try it.)
Fgrep still has its uses though, and may be useful when searching
a file for a larger number of strings than egrep can handle.
egrep = "Extended GREP"
egrep uses fancier regular expressions than grep. Many people
use egrep all the time, since it has some more sophisticated
internal algorithms than grep or fgrep, and is usually the
fastest of the three programs.
cat = "CATenate"
catenate is an obscure word meaning "to connect in a series",
which is what the "cat" command does to one or more files. Not
to be confused with C/A/T, the Computer Aided Typesetter.
gecos = "General Electric Comprehensive Operating Supervisor"
When GE's large systems division was sold to Honeywell,
Honeywell dropped the "E" from "GECOS".
Unix's password file has a "pw_gecos" field. The name is a
real holdover from the early days. Dennis Ritchie has reported:
"Sometimes we sent printer output or batch jobs
to the GCOS machine. The gcos field in the password file
was a place to stash the information for the $IDENT card.
Not elegant."
nroff = "New ROFF"
troff = "Typesetter new ROFF"
These are descendants of "roff", which was a re-implementation
of the Multics "runoff" program (a program that you'd use to
"run off" a good copy of a document).
tee = T
From plumbing terminology for a T-shaped pipe splitter.
bss = "Block Started by Symbol"
Dennis Ritchie says:
Actually the acronym (in the sense we took it up; it may
have other credible etymologies) is "Block Started by
Symbol." It was a pseudo-op in FAP (Fortran Assembly [-er?]
Program), an assembler for the IBM 704-709-7090-7094
machines. It defined its label and set aside space for a
given number of words. There was another pseudo-op, BES,
"Block Ended by Symbol" that did the same except that the
label was defined by the last assigned word + 1. (On these
machines Fortran arrays were stored backwards in storage
and were 1-origin.)
The usage is reasonably appropriate, because just as with
standard Unix loaders, the space assigned didn't have to be
punched literally into the object deck but was represented
by a count somewhere.
biff = "BIFF"
This command, which turns on asynchronous mail notification,
was actually named after a dog at Berkeley.
I can confirm the origin of biff, if you're interested.
Biff was Heidi Stettner's dog, back when Heidi (and I, and
Bill Joy) were all grad students at U.C. Berkeley and the
early versions of BSD were being developed. Biff was
popular among the residents of Evans Hall, and was known
for barking at the mailman, hence the name of the command.

rc (as in ".cshrc" or "/etc/rc") = "RunCom"
"rc" derives from "runcom", from the MIT CTSS system, ca. 1965.
'There was a facility that would execute a bunch of
commands stored in a file; it was called "runcom" for "run
commands", and the file began to be called "a runcom."
"rc" in Unix is a fossil from that usage.'
Brian Kernighan & Dennis Ritchie, as told to Vicki Brown
"rc" is also the name of the shell from the new Plan 9
operating system.
Perl = "Practical Extraction and Report Language"
Perl = "Pathologically Eclectic Rubbish Lister"
The Perl language is Larry Wall's highly popular
freely-available completely portable text, process, and file
manipulation tool that bridges the gap between shell and C
programming (or between doing it on the command line and
pulling your hair out). For further information, see the
Usenet newsgroup comp.lang.perl.misc.
Don Libes' book "Life with Unix" contains lots more of these
tidbits.
