.SH DESCRIPTION
|
|
|
|
.LP
|
|
|
|
The \fIadmin\fP utility shall create new SCCS files or change parameters
|
|
|
|
of existing ones. If a named file does not exist, it
|
|
|
|
shall be created, and its parameters shall be initialized according
|
|
|
|
to the specified options. Parameters not initialized by an
|
|
|
|
option shall be assigned a default value. If a named file does exist,
|
|
|
|
parameters corresponding to specified options shall be
|
|
|
|
changed, and other parameters shall be left as is.
|
|
|
|
.LP
|
|
|
|
All SCCS filenames supplied by the application shall be of the form
|
|
|
|
s.\fIfilename\fP. New SCCS files shall be given read-only
|
|
|
|
permission mode. Write permission in the parent directory is required
|
|
|
|
to create a file. All writing done by \fIadmin\fP shall be
|
|
|
|
to a temporary \fIx-file\fP, named x.\fIfilename\fP (see \fIget\fP
|
|
|
|
) created with read-only mode if
|
|
|
|
\fIadmin\fP is creating a new SCCS file, or created with the same
|
|
|
|
mode as that of the SCCS file if the file already exists. After
|
|
|
|
successful execution of \fIadmin\fP, the SCCS file shall be removed
|
|
|
|
(if it exists), and the \fIx-file\fP shall be renamed with
|
|
|
|
the name of the SCCS file. This ensures that changes are made to the
|
|
|
|
SCCS file only if no errors occur.
|
|
|
|
.LP
|
|
|
|
The \fIadmin\fP utility shall also use a transient lock file (named
|
|
|
|
z.\fIfilename\fP), which is used to prevent simultaneous
|
|
|
|
updates to the SCCS file; see \fIget\fP .
|
|
|
|
.SH OPTIONS
|
|
|
|
.LP
|
|
|
|
The \fIadmin\fP utility shall conform to the Base Definitions volume
|
|
|
|
of IEEE\ Std\ 1003.1-2001, Section 12.2, Utility Syntax Guidelines,
|
|
|
|
except that the \fB-i\fP, \fB-t\fP, and
|
|
|
|
\fB-y\fP options have optional option-arguments. These optional option-arguments
|
|
|
|
shall not be presented as separate arguments. The
|
|
|
|
following options are supported:
|
|
|
|
.TP 7
|
|
|
|
\fB-n\fP
|
|
|
|
Create a new SCCS file. When \fB-n\fP is used without \fB-i\fP, the
|
|
|
|
SCCS file shall be created with control information but
|
|
|
|
without any file data.
|
|
|
|
.TP 7
|
|
|
|
\fB-i[\fP\fIname\fP\fB]\fP
|
|
|
|
Specify the \fIname\fP of a file from which the text for a new SCCS
|
|
|
|
file shall be taken. The text constitutes the first delta
|
|
|
|
of the file (see the \fB-r\fP option for the delta numbering scheme).
|
|
|
|
If the \fB-i\fP option is used, but the \fIname\fP
|
|
|
|
option-argument is omitted, the text shall be obtained by reading
|
|
|
|
the standard input. If this option is omitted, the SCCS file
|
|
|
|
shall be created with control information but without any file data.
|
|
|
|
The \fB-i\fP option implies the \fB-n\fP option.
|
|
|
|
.TP 7
|
|
|
|
\fB-r\ \fP \fISID\fP
|
|
|
|
Specify the SID of the initial delta to be inserted. This SID shall
|
|
|
|
be a trunk SID; that is, the branch and sequence numbers
|
|
|
|
shall be zero or missing. The level number is optional, and defaults
|
|
|
|
to 1.
|
|
|
|
.TP 7
|
|
|
|
\fB-t[\fP\fIname\fP\fB]\fP
|
|
|
|
Specify the \fIname\fP of a file from which descriptive text for the
|
|
|
|
SCCS file shall be taken. In the case of existing SCCS
|
|
|
|
files (neither \fB-i\fP nor \fB-n\fP is specified):

|
|

.RS

A \fB-t\fP option without a \fIname\fP option-argument shall cause

the removal of descriptive text (if any) currently in the
|
|
|
|
SCCS file.

The character \fIa\fP in the \fIlist\fP shall be equivalent to specifying

all releases for the named SCCS file. The

\fBn\fP

|

Cause \fIdelta\fP to create a null delta in each of those releases
|
|
|
|
(if any) being
|
|
|
|
skipped when a delta is made in a new release (for example, in making
|
|
|
|
delta 5.1 after delta 2.7, releases 3 and 4 are skipped).
|
|
|
|
These null deltas shall serve as anchor points so that branch deltas
|
|
|
|
may later be created from them. The absence of this flag shall
|
|
|
|
cause skipped releases to be nonexistent in the SCCS file, preventing
|
|
|
|
branch deltas from being created from them in the future.
|
|
|
|
During the initial creation of an SCCS file, the \fBn\fP flag may
|
|
|
|
be ignored; that is, if the \fB-r\fP option is used to set the
|
|
|
|
release number of the initial SID to a value greater than 1, null
|
|

deltas need not be created for the "skipped" releases.

.TP 7
|

|
|
\fIfile\fP
|
|
|
|
A pathname of an existing SCCS file or a directory. If \fIfile\fP
|
|
|
|
is a directory, the \fIadmin\fP utility shall behave as
|
|
|
|
though each file in the directory were specified as a named file,
|
|
|
|
except that non-SCCS files (last component of the pathname does
|
|
|
|
not begin with \fBs.\fP) and unreadable files shall be silently ignored.
|
|
|
|
.TP 7
|
|
|
|
\fInewfile\fP
|
|
|
|
A pathname of an SCCS file to be created.

If exactly one \fIfile\fP or \fInewfile\fP operand appears, and it
|
2007-09-20 06:36:16 +00:00
|
|

is \fB'-'\fP, the standard input shall be read; each
|
2004-11-03 13:51:07 +00:00
|
|
|
line of the standard input shall be taken to be the name of an SCCS
|
|

file to be processed. Non-SCCS files and unreadable files shall
|
|
|
|
be silently ignored.
|
|
|
|
.SH STDIN
|

|
|
.LP
|
|
|

The standard input shall be a text file used only if \fB-i\fP is specified
|
|
|
|
without an option-argument or if a \fIfile\fP or
|
|
|
|
\fInewfile\fP operand is specified as \fB'-'\fP . If the first character
|
|
|
|
of any standard input line is <SOH> in the POSIX
|
|
|
|
locale, the results are unspecified.
|

.SH INPUT FILES
|
|
|
|
.LP
|
|

The existing SCCS files shall be text files of an unspecified format.

.LP
|
|
|

The application shall ensure that the file named by the \fB-i\fP option's
|
|
|
|
\fIname\fP option-argument shall be a text file; if
|
|
|
|
the first character of any line in this file is <SOH> in the POSIX
|
|
|
|
locale, the results are unspecified. If this file contains
|
|
|
|
more than 99999 lines, the number of lines recorded in the header
|
|
|
|
for this file shall be 99999 for this delta.

The following environment variables shall affect the execution of

.TP 7
|

|
\fILANG\fP
|
|
|
|
Provide a default value for the internationalization variables that
|
|

are unset or null. (See the Base Definitions volume of

IEEE\ Std\ 1003.1-2001, Section 8.2, Internationalization Variables

the values of locale categories.)

.TP 7

\fILC_ALL\fP

If set to a non-empty string value, override the values of all the

|
|
other internationalization variables.
|

.TP 7
|
|
|
|
\fILC_CTYPE\fP
|
|
|
|
Determine the locale for the interpretation of sequences of bytes
|
|
|
|
of text data as characters (for example, single-byte as
|
|
|
|
opposed to multi-byte characters in arguments and input files).
|
|
|
|
.TP 7
|
|
|
|
\fILC_MESSAGES\fP
|
|
|
|
Determine the locale that should be used to affect the format and
|
|
|
|
contents of diagnostic messages written to standard error and
|
|
|
|
the contents of the default \fB-y\fP comment.

.SH APPLICATION USAGE
|
|
|
|
.LP
|
|
|
|
It is recommended that directories containing SCCS files be writable
|
|
|
|
by the owner only, and that SCCS files themselves be
|
|
|
|
read-only. The mode of the directories should allow only the owner
|
|
|
|
to modify SCCS files contained in the directories. The mode of
|
|
|
|
the SCCS files prevents any modification at all except by SCCS commands.
