User Commands sccs(1)
NAME
sccs - front end for the Source Code Control System (SCCS)
SYNOPSIS
/usr/ccs/bin/sccs [-r] [-drootprefix] [-psubdir] subcommand
[option...] [file...]
/usr/xpg4/bin/sccs [-r] [-d rootprefix] [-p subdir] subcom-
mand [option...] [file...]
DESCRIPTION
The sccs command is a comprehensive, straightforward front
end to the various utility programs of the Source Code Con-
trol System (SCCS).
sccs applies the indicated subcommand to the history file
associated with each of the indicated files.
The name of an SCCS history file is derived by prepending
the `s.' prefix to the filename of a working copy. The sccs
command normally expects these `s.files' to reside in an
SCCS subdirectory. Thus, when you supply sccs with a file
argument, it normally applies the subcommand to a file named
s.file in the SCCS subdirectory. If file is a path name,
sccs looks for the history file in the SCCS subdirectory of
that file's parent directory. If file is a directory, how-
ever, sccs applies the subcommand to every s.file file it
contains. Thus, the command:
example% sccs get program.c
would apply the get subcommand to a history file named
SCCS/s.program.c, while the command:
example% sccs get SCCS
would apply it to every s.file in the SCCS subdirectory.
Options for the sccs command itself must appear before the
subcommand argument. Options for a given subcommand must
appear after the subcommand argument. These options are
specific to each subcommand, and are described along with
the subcommands themselves (see Subcommands below).
Running Setuid
The sccs command also includes the capability to run
``setuid'' to provide additional protection. However, this
does not apply to subcommands such as sccs-admin(1), since
this would allow anyone to change the authorizations of the
history file. Commands that would do so always run as the
real user.

User Commands sccs(1)
OPTIONS
The following options are supported:
/usr/ccs/bin/sccs
-drootprefix
/usr/xpg4/bin/sccs
-d rootprefix Defines the root portion of the path name
for SCCS history files. The default root
portion is the current directory. rootprefix
is prepended to the entire file argument,
even if file is an absolute path name. -d
overrides any directory specified by the
PROJECTDIR environment variable (see
ENVIRONMENT VARIABLES below).
/usr/ccs/bin/sccs
-psubdir
/usr/xpg4/bin/sccs
-p subdir Defines the (sub)directory within which a
history file is expected to reside. SCCS is
the default. (See EXAMPLES below).
-r Runs sccs with the real user ID, rather than
set to the effective user ID.
OPERANDS
The following operands are supported:
subcommand An SCCS utility name or the name of one of
the pseudo-utilities listed in USAGE.
options An option or option-argument to be passed to
subcommand.
operands An operand to be passed to subcommand.
USAGE
SunOS 5.10 Last change: 28 Sep 2001 2
User Commands sccs(1)
The usage for sccs is described below.
Subcommands
Many of the following sccs subcommands invoke programs that
reside in /usr/ccs/bin. Many of these subcommands accept
additional arguments that are documented in the reference
page for the utility program the subcommand invokes.
admin Modify the flags or checksum of an SCCS his-
tory file. Refer to sccs-admin(1) for more
information about the admin utility. While
admin can be used to initialize a history
file, you may find that the create subcom-
mand is simpler to use for this purpose.
/usr/ccs/bin/sccs
cdc -rsid [ -y[comment]]
/usr/xpg4/bin/sccs
cdc -rsid | -rsid [ -y[comment]]
Annotate (change) the delta commentary. Refer to sccs-
cdc(1). The fix subcommand can be used to replace the
delta, rather than merely annotating the existing com-
mentary.
/usr/ccs/bin/sccs
-rsid
/usr/xpg4/bin/sccs
-r sid | -rsid
Specify the SCCS delta ID (SID) to which the
change notation is to be added. The SID for a
given delta is a number, in Dewey decimal for-
mat, composed of two or four fields: the
release and level fields, and for branch del-
tas, the branch and sequence fields. For
instance, the SID for the initial delta is nor-
mally 1.1.
-y"[comment]"
Specify the comment with which to annotate the
delta commentary. If -y is omitted, sccs
SunOS 5.10 Last change: 28 Sep 2001 3
User Commands sccs(1)
prompts for a comment. A null comment results
in an empty annotation.
/usr/ccs/bin/sccs
check [-b] [-u[username] ]
/usr/xpg4/bin/sccs
check [-b] [-u [username] | -U ]
Check for files currently being edited. Like info and
tell, but returns an exit code, rather than producing a
listing of files. check returns a non-zero exit status
if anything is being edited.
-b Ignore branches.
/usr/ccs/bin/sccs
-u[username
/usr/xpg4/bin/sccs
-u [ username]| -U Check only files being edited by
you. When username is speci-
fied, check only files being
edited by that user. For
/usr/xpg4/bin/sccs, the -U
option is equivalent to -u
<current_user>.
clean [ -b ]
Remove everything in the current directory that can be
retrieved from an SCCS history. Does not remove files
that are being edited.
-b Do not check branches to see if they are being
edited. `clean -b' is dangerous when branch
versions are kept in the same directory.

User Commands sccs(1)
comb
Generate scripts to combine deltas. Refer to sccs-
comb(1).
create
Create (initialize) history files. create performs the
following steps:
o Renames the original source file to ,program.c in
the current directory.
o Create the history file called s.program.c in the
SCCS subdirectory.
o Performs an `sccs get' on program.c to retrieve a
read-only copy of the initial version.
deledit [-s] [-y[comment]]
Equivalent to an `sccs delta' and then an `sccs edit'.
deledit checks in a delta, and checks the file back out
again, but leaves the current working copy of the file
intact.
-s Silent. Do not report delta numbers or
statistics.
-y[comment] Supply a comment for the delta commen-
tary. If -y is omitted, delta prompts
for a comment. A null comment results
in an empty comment field for the delta.
delget [-s] [-y[comment]]
Perform an `sccs delta' and then an `sccs get' to check
in a delta and retrieve read-only copies of the result-
ing new version. See the deledit subcommand for a
description of -s and -y. sccs performs a delta on all
SunOS 5.10 Last change: 28 Sep 2001 5
User Commands sccs(1)
the files specified in the argument list, and then a
get on all the files. If an error occurs during the
delta, the get is not performed.
delta [-s] [-y[comment]]
Check in pending changes. Records the line-by-line
changes introduced while the file was checked out. The
effective user ID must be the same as the ID of the per-
son who has the file checked out. Refer to sccs-
delta(1). See the deledit subcommand for a description
of -s and -y.
/usr/ccs/bin/sccs
diffs [-C] [-I] [-cdate-time] [-rsid] diff-options
/usr/xpg4/bin/sccs
diffs [-C] [-I] [-c date-time | -cdate-time ]
[-r sid | -rsid] diff-options
Compare (in diff (1) format) the working copy of a file
that is checked out for editing, with a version from the
SCCS history. Use the most recent checked-in version by
default. The diffs subcommand accepts the same options
as diff.
Any -r, -c, -i, -x, and -t options are passed to subcom-
mand get. A -C option is passed to diff as -c. An -I
option is passed to diff as -i.
/usr/ccs/bin/sccs
-cdate-time
/usr/xpg4/bin/sccs
-c date-time | -cdate-time
Use the most recent version checked in before the
indicated date and time for comparison. date-time
takes the form: yy[mm[dd[ hh[mm[ss]]]]]. Omitted
units default to their maximum possible values; that
is -c7502 is equivalent to -c750228235959.
SunOS 5.10 Last change: 28 Sep 2001 6
User Commands sccs(1)
/usr/ccs/bin/sccs
-rsid
/usr/xpg4/bin/sccs
-r sid | -rsid Use the version corresponding to the
indicated delta for comparison.
edit Retrieve a version of the file for editing.
`sccs edit' extracts a version of the file
that is writable by you, and creates a
p.file in the SCCS subdirectory as lock on
the history, so that no one else can check
that version in or out. ID keywords are
retrieved in unexpanded form. edit accepts
the same options as get, below. Refer to
sccs-get(1) for a list of ID keywords and
their definitions.
enter Similar to create, but omits the final `sccs
get'. This may be used if an `sccs edit' is
to be performed immediately after the his-
tory file is initialized.
/usr/ccs/bin/sccs
fix -rsid
/usr/xpg4/bin/sccs
fix -r sid | -rsid
Revise a (leaf) delta. Remove the indicated delta from
the SCCS history, but leave a working copy of the
current version in the directory. This is useful for
incorporating trivial updates for which no audit record
is needed, or for revising the delta commentary. fix
must be followed by a -r option, to specify the SID of
the delta to remove. The indicated delta must be the
most recent (leaf) delta in its branch. Use fix with
caution since it does not leave an audit trail of
differences (although the previous commentary is
retained within the history file).

User Commands sccs(1)
/usr/ccs/bin/sccs
get [-ekmps] [-Gnewname] [-cdate-time] [-r[sid] ]
/usr/xpg4/bin/sccs
get [-ekmps] [-G newname | -Gnewname]
[-c date-time | -cdate-time] [-r sid | -rsid]
Retrieve a version from the SCCS history. By default,
this is a read-only working copy of the most recent ver-
sion. ID keywords are in expanded form. Refer to sccs-
get(1), which includes a list of ID keywords and their
definitions.
-e Retrieve a version for editing.
Same as sccs edit.
-G newname | -Gnewname Use newname as the name of the
retrieved version.
-k Retrieve a writable copy but do
not check out the file. ID key-
words are unexpanded.
-m Precede each line with the SID
of the delta in which it was
added.
-p Produce the retrieved version on
the standard output. Reports
that would normally go to the
standard output (delta IDs and
statistics) are directed to the
standard error.
-s Silent. Do not report version
numbers or statistics.

the indicated SID.
help message-code|sccs-command
help stuck
Supply more information about SCCS diagnostics. help
displays a brief explanation of the error when you sup-
ply the code displayed by an SCCS diagnostic message.
If you supply the name of an SCCS command, it prints a
usage line. help also recognizes the keyword stuck.

EXAMPLES
Example 1: Checking out, editing, and checking in a file
To check out a copy of program.c for editing, edit it, and
then check it back in:
example% sccs edit program.c
1.1
new delta 1.2
14 lines
example% vi program.c
your editing session
example% sccs delget program.c
comments? clarified cryptic diagnostic

Example 2: Defining the root portion of the command pathname
sccs converts the command:
example% sccs -d/usr/src/include get stdio.h
to:
/usr/ccs/bin/get /usr/src/include/SCCS/s.stdio.h
Example 3: Defining the resident subdirectory
The command:
SunOS 5.10 Last change: 28 Sep 2001 13
User Commands sccs(1)
example% sccs -pprivate get include/stdio.h
becomes:
/usr/ccs/bin/get include/private/s.stdio.h
Example 4: Initializing a history file
To initialize the history file for a source file named
program.c, make the SCCS subdirectory, and then use `sccs
create':
example% mkdir SCCS
example% sccs create program.c
program.c:
1.1
14 lines
After verifying the working copy, you can remove the backup
file that starts with a comma:
example% diff program.c ,program.c
example% rm ,program.c
Example 5: Retrieving a file from another directory
To retrieve a file from another directory into the current
directory:
example% sccs get /usr/src/sccs/cc.c
or:
example% sccs -p/usr/src/sccs/ get cc.c
Example 6: Checking out all files
To check out all files under SCCS in the current directory:
example% sccs edit SCCS
Example 7: Checking in all files
To check in all files currently checked out to you:
example% sccs delta `sccs tell -u`
Example 8: Entering multiple lines of comments
If using -y to enter a comment, for most shells, enclose the
comment in single or double quotes. In the following exam-
ple, Myfile is checked in with a two-line comment:

ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment
variables that affect the execution of sccs: LANG, LC_ALL,
LC_CTYPE, LC_MESSAGES, and NLSPATH.
PROJECTDIR If contains an absolute path name (beginning
with a slash), sccs searches for SCCS his-
tory files in the directory given by that
variable.
If PROJECTDIR does not begin with a slash,
it is taken as the name of a user, and sccs
searches the src or source subdirectory of
that user's home directory for history
files. If such a directory is found, it is

used. Otherwise, the value is used as a
relative path name.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
SCCS SCCS subdirectory
SCCS/d.file temporary file of differences
SCCS/p.file lock (permissions) file for
checked-out versions
