_\bS_\bc_\bc_\bs is a front end to the SCCS programs that helps them
mesh more cleanly with the rest of UNIX. It also includes
the capability to run ``set user id'' to another user to
provide additional protection.
Basically, _\bs_\bc_\bc_\bs runs the _\bc_\bo_\bm_\bm_\ba_\bn_\bd with the specified _\bf_\bl_\ba_\bg_\bs
and _\ba_\br_\bg_\bs. Each argument is normally modified to be prepended
with ``SCCS/s.''.
Flags to be interpreted by the _\bs_\bc_\bc_\bs program must be before
the _\bc_\bo_\bm_\bm_\ba_\bn_\bd argument. Flags to be passed to the actual SCCS
program must come after the _\bc_\bo_\bm_\bm_\ba_\bn_\bd argument. These flags
are specific to the command and are discussed in the docu-
mentation for that command.
Besides the usual SCCS commands, several ``pseudo-commands''
can be issued. These are:
edit Equivalent to ``get -e''.
delget Perform a delta on the named files and then get
new versions. The new versions will have id key-
words expanded, and will not be editable. The -m,
-p, -r, -s, and -y flags will be passed to delta,
and the -b, -c, -e, -i, -k, -l, -s, and -x flags
will be passed to get.
deledit Equivalent to ``delget'' except that the ``get''
phase includes the ``-e'' flag. This option is
useful for making a ``checkpoint'' of your current
editing phase. The same flags will be passed to
delta as described above, and all the flags listed
for ``get'' above except -e and -k are passed to
``edit''.
create Creates an SCCS file, taking the initial contents
from the file of the same name. Any flags to
``admin'' are accepted. If the creation is suc-
cessful, the files are renamed with a comma on the
front. These should be removed when you are con-
vinced that the SCCS files have been created suc-
cessfully.
fix Must be followed by a -\b-r\br flag. This command
essentially removes the named delta, but leaves

SCCS(1) UNIX Programmer's Manual SCCS(1)
you with a copy of the delta with the changes that
were in it. It is useful for fixing small com-
piler bugs, etc. Since it doesn't leave audit
trails, it should be used carefully.
clean This routine removes everything from the current
directory that can be recreated from SCCS files.
It will not remove any files being edited. If the
-\b-b\bb flag is given, branches are ignored in the
determination of whether they are being edited;
this is dangerous if you are keeping the branches
in the same directory.
unedit This is the opposite of an ``edit'' or a ``get
-e''. It should be used with extreme caution,
since any changes you made since the get will be
irretrievably lost.
info Gives a listing of all files being edited. If the
-\b-b\bb flag is given, branches (i.e., SID's with two
or fewer components) are ignored. If the -\b-u\bu flag
is given (with an optional argument) then only
files being edited by you (or the named user) are
listed.
check Like ``info'' except that nothing is printed if
nothing is being edited, and a non-zero exit
status is returned if anything is being edited.
The intent is to have this included in an
``install'' entry in a makefile to insure that
everything is included into the SCCS file before a
version is installed.
tell Gives a newline-separated list of the files being
edited on the standard output. Takes the -\b-b\bb and
-\b-u\bu flags like ``info'' and ``check''.
diffs Gives a ``diff'' listing between the current ver-
sion of the program(s) you have out for editing
and the versions in SCCS format. The -\b-r\br,\b, -\b-c\bc,\b, -\b-i\bi,\b,
-\b-x\bx,\b, and -\b-t\bt flags are passed to _\bg_\be_\bt; the -\b-l\bl,\b, -\b-s\bs,\b,
-\b-e\be,\b, -\b-f\bf,\b, -\b-h\bh,\b, and -\b-b\bb options are passed to _\bd_\bi_\bf_\bf. The
-\b-C\bC flag is passed to _\bd_\bi_\bf_\bf as -\b-c\bc.\b.
print This command prints out verbose information about
the named files.
The -\b-r\br flag runs _\bs_\bc_\bc_\bs as the real user rather than as what-
ever effective user _\bs_\bc_\bc_\bs is ``set user id'' to. The -\b-d\bd flag
gives a root directory for the SCCS files. The default is
the current directory. The -\b-p\bp flag defines the pathname of
the directory in which the SCCS files will be found;

``SCCS'' is the default. The -\b-p\bp flag differs from the -\b-d\bd
flag in that the -\b-d\bd argument is prepended to the entire
pathname and the -\b-p\bp argument is inserted before the final
component of the pathname. For example, ``sccs -d/x -py get
a/b'' will convert to ``get /x/a/y/s.b''. The intent here
is to create aliases such as ``alias syssccs sccs
-d/usr/src'' which will be used as ``syssccs get
cmd/who.c''. Also, if the environment variable PROJECT is
set, its value is used to determine the -\b-d\bd f\bfl\bla\bag\bg.\b. If it
begins with a slash, it is taken directly; otherwise, the
home directory of a user of that name is examined for a sub-
directory ``src'' or ``source''. If such a directory is
found, it is used.
Certain commands (such as _\ba_\bd_\bm_\bi_\bn) cannot be run ``set user
id'' by all users, since this would allow anyone to change
the authorizations. These commands are always run as the
real user.

To get a file for editing, edit it, and produce a new delta:
sccs get -e file.c
ex file.c
sccs delta file.c
To get a file from another directory:
sccs -p/usr/src/sccs/s. get cc.c
or
sccs get /usr/src/sccs/s.cc.c
To make a delta of a large number of files in the current
directory:
sccs delta *.c
To get a list of files being edited that are not on
branches:
sccs info -b
To delta everything being edited by you:
sccs delta `sccs tell -u`
In a makefile, to get source files from an SCCS file if it
does not already exist:
