.Sh DESCRIPTION
|
|
.Nm Sccs
|
|
is a front end to the
|
|
.Li SCCS
|
|
programs
|
|
that
|
|
helps them mesh more cleanly
|
|
with
|
|
the rest of UNIX.
|
|
It
|
|
also includes the capability to run
|
|
.Dq set user id
|
|
to another user
|
|
to
|
|
provide additional protection.
|
|
.Pp
|
|
Basically,
|
|
.Nm sccs
|
|
runs the command with the specified
|
|
.Ar flags
|
|
and
|
|
.Ar args .
|
|
Each argument is normally modified to be prepended with
|
|
.Dq Li SCCS/s. .
|
|
.Pp
|
|
Flags to be interpreted by the
|
|
.Nm sccs
|
|
program must be before the
|
|
.Ar command
|
|
argument.
|
|
Flags to be passed to the actual
|
|
.Li SCCS
|
|
program must come after the
|
|
.Ar command
|
|
argument.
|
|
These flags are specific to the command and
|
|
are discussed in the documentation for that command.
|
|
.Pp
|
|
Besides the usual
|
|
.Li SCCS
|
|
commands,
|
|
several
|
|
.Dq pseudo-commands
|
|
can be issued.
|
|
These are:
|
|
.Bl -tag -width deledit
|
|
.It Cm edit
|
|
Equivalent
|
|
to
|
|
.Dq Li get \-e .
|
|
.It Cm delget
|
|
Perform a delta on the named files and
|
|
then get new versions.
|
|
The new versions will have id keywords expanded, and
|
|
will not be editable.
|
|
The
|
|
.Fl m ,
|
|
.Fl p ,
|
|
.Fl r ,
|
|
.Fl s ,
|
|
and
|
|
.Fl y
|
|
flags will be passed to
|
|
.Nm delta ,
|
|
and the
|
|
.Fl b,
|
|
.Fl c ,
|
|
.Fl e ,
|
|
.Fl i ,
|
|
.Fl k ,
|
|
.Fl l ,
|
|
.Fl s ,
|
|
.\" anybody who has a bad xterm which is almost anyone
|
|
and
|
|
.Fl x
|
|
flags will be passed to get.
|
|
.It Cm deledit
|
|
Equivalent
|
|
to
|
|
.Nm delget
|
|
except that the
|
|
.Nm get
|
|
phase includes the
|
|
.Fl e
|
|
flag.
|
|
This
|
|
option is useful for making a
|
|
.Em checkpoint
|
|
of your current editing phase. The same flags will be passed to delta
|
|
as described above, and
|
|
all the flags listed for
|
|
.om get
|
|
above except
|
|
.Fl e
|
|
and
|
|
.Fl k
|
|
are
|
|
passed to
|
|
.Nm edit .
|
|
.It Cm create
|
|
Creates
|
|
an
|
|
.Li SCCS
|
|
file ,
|
|
taking
|
|
the initial contents from the file of the same name.
|
|
Any
|
|
flags to
|
|
.Nm admin
|
|
are accepted. If the creation is successful,
|
|
the files are renamed with a comma on the front.
|
|
These should be removed when you are convinced that the
|
|
.Li SCCS
|
|
files
|
|
have been created successfully.
|
|
.It Cm fix
|
|
Must
|
|
be followed by a
|
|
.Fl r
|
|
flag.
|
|
This command essentially removes the named delta, but
|
|
leaves you with a copy of the delta
|
|
with the changes that were in it. It
|
|
is useful for fixing small compiler bugs, etc.
|
|
Since it doesn't leave audit trails, it should be used carefully.
|
|
.It Cm 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
|
|
.Fl b
|
|
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.
|
|
.It Cm unedit
|
|
This
|
|
is the opposite of an
|
|
.Nm edit
|
|
or
|
|
a
|
|
.Dq Li get \-e .
|
|
It should be used with extreme caution, since
|
|
any changes you made since the get will be irretrievably lost.
|
|
.It Cm info
|
|
Gives a listing of all files being edited.
|
|
If the
|
|
.Fl b
|
|
flag
|
|
is given, branches (i.e.,
|
|
.Li SID Ns \&\'s
|
|
with two or fewer components)
|
|
are ignored. If the
|
|
.Fl u
|
|
flag is given (with an optional argument) then
|
|
only files being edited by you (or the named user) are listed.
|
|
.It Cm check
|
|
Like
|
|
.Nm 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
|
|
.Em install
|
|
entry in a makefile to insure that everything is included into the
|
|
.Li SCCS
|
|
file before a version is installed.
|
|
.It Cm tell
|
|
Gives a newline-separated list of the files being edited
|
|
on the standard output. Takes the
|
|
.Fl b
|
|
and
|
|
.Fl u
|
|
flags like
|
|
.Nm info
|
|
and
|
|
.Nm check .
|
|
.It Cm diffs
|
|
Gives a
|
|
.Nm diff
|
|
listing between the current version of the
|
|
program(s) you have out for editing and the versions in
|
|
.Li SCCS
|
|
format.
|
|
The
|
|
.Fl r ,
|
|
.Fl c ,
|
|
.Fl i ,
|
|
.Fl x ,
|
|
and
|
|
.Fl t
|
|
flags are passed to
|
|
.if n \{\
|
|
. br
|
|
.\}
|
|
.Nm get ;
|
|
the
|
|
.Fl l ,
|
|
.Fl s ,
|
|
.Fl e ,
|
|
.Fl f ,
|
|
.Fl h ,
|
|
and
|
|
.Fl b
|
|
options are passed to
|
|
.if n \{\
|
|
. br
|
|
.\}
|
|
.Nm diff .
|
|
The
|
|
.Fl C
|
|
flag is passed to
|
|
.Nm diff
|
|
as
|
|
.Fl c .
|
|
.It Cm print
|
|
This command prints out verbose information
|
|
about the named files.
|
|
.Pp
|
|
.It Fl r
|
|
Runs
|
|
.Nm sccs
|
|
as the real user rather than as whatever effective user
|
|
.Nm sccs
|
|
is
|
|
.Dq Li set user id
|
|
to.
|
|
.It Fl d
|
|
Specifies a root directory for the
|
|
.Li SCCS
|
|
files.
|
|
The default is the current directory.
|
|
If environment variable
|
|
.Ev PROJECT
|
|
is set,
|
|
it will be used to determine the
|
|
.Fl d
|
|
flag.
|
|
.It Fl p
|
|
Defines the pathname of the directory in which the
|
|
.Li SCCS
|
|
files will be found;
|
|
.Dq Li SCCS
|
|
is the default.
|
|
The
|
|
.Fl p
|
|
flag
|
|
differs from the
|
|
.Fl d
|
|
flag
|
|
in that the
|
|
.Fl d
|
|
argument is prepended to the entire pathname and the
|
|
.Fl p
|
|
argument is inserted before the final component of the pathname.
|
|
For example,
|
|
.Dq Li sccs \-d/x \-py get a/b
|
|
will convert to
|
|
.Dq Li get /x/a/y/s.b .
|
|
The intent here is to create aliases such as
|
|
.Dq Li alias syssccs sccs -d/usr/src
|
|
which
|
|
will be used as
|
|
.Dq Li syssccs get cmd/who.c .
|
|
.Pp
|
|
Certain
|
|
commands (such as
|
|
.Nm admin )
|
|
cannot be run
|
|
.Dq Li set user id
|
|
by all users, since this would allow anyone to change the authorizations.
|
|
These commands are always run as the real user.
|
|
.Sh EXAMPLES
|
|
To get a file for editing,
|
|
edit it,
|
|
and produce a new delta:
|
|
.Pp
|
|
.Dl sccs get \-e file.c
|
|
.Dl ex file.c
|
|
.Dl sccs delta file.c
|
|
.Pp
|
|
To get a file from another directory:
|
|
.Pp
|
|
.Dl sccs \-p/usr/src/sccs/s. get cc.c
|
|
.Pp
|
|
or
|
|
.Pp
|
|
.Dl sccs get /usr/src/sccs/s.cc.c
|
|
.Pp
|
|
To make a delta of a large number of files
|
|
in the current directory:
|
|
.Pp
|
|
.Dl sccs delta *.c
|
|
.Pp
|
|
To get a list of files being edited that are not on branches:
|
|
.Pp
|
|
.Dl sccs info \-b
|
|
.Pp
|
|
To delta everything being edited by you:
|
|
.Pp
|
|
.Dl sccs delta \`sccs tell \-u\`
|
|
.Pp
|
|
In a makefile, to get source files
|
|
from an
|
|
.Li SCCS
|
|
file if it does not already exist:
|
|
.Pp
|
|
.Dl SRCS = <list of source files>
|
|
.Dl $(SRCS):
|
|
.Dl \&\tsccs get $(REL) $@
|
|
.Sh ENVIRONMENT
|
|
.Bl -tag -width Ar
|
|
.It Ev PROJECT
|
|
The PROJECT environment variable is checked by the
|
|
.Fl d
|
|
flag. If
|
|
it begins with a slash, it is taken directly; otherwise,
|
|
the home directory of a user of that name is
|
|
examined for a subdirectory
|
|
.Dq Li src
|
|
or
|
|
.Dq Li source .
|
|
If such a directory is found, it is used.
