All SCCS filenames supplied by the application shall be of the form s.filename. 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 admin shall be to a temporary x-file, named x.filename (see get) created with read-only mode if admin 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 admin, the SCCS file shall be removed (if it exists), and the x-file 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.
The admin utility shall also use a transient lock file (named z.filename), which is used to prevent simultaneous updates to the SCCS file; see get.
- Create a new SCCS file. When -n is used without -i, the SCCS file shall be created with control information but without any file data.
- Specify the name 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 -r option for the delta numbering scheme). If the -i option is used, but the name 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 -i option implies the -n option.
- -r SID
- 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.
- Specify the name of a file from which descriptive text for the SCCS file shall be taken. In the case of existing SCCS files (neither -i nor -n is specified):
- A -t option without a name option-argument shall cause the removal of descriptive text (if any) currently in the SCCS file.
- A -t option with a name option-argument shall cause the text (if any) in the named file to replace the descriptive text (if any) currently in the SCCS file.
- -f flag
- Specify a flag, and, possibly, a value for the flag, to be placed in the SCCS file. Several -f options may be supplied on a single admin command line. Implementations shall recognize the following flags and associated values:
- Allow use of the -b option on a get command to create branch deltas.
- Specify the highest release (that is, ceiling), a number less than or equal to 9999, which may be retrieved by a get command for editing. The default value for an unspecified c flag shall be 9999.
- Specify the lowest release (that is, floor), a number greater than 0 but less than 9999, which may be retrieved by a get command for editing. The default value for an unspecified f flag shall be 1.
- Specify the default delta number (SID) to be used by a get command.
- Treat the ``No ID keywords'' message issued by get or delta as a fatal error. In the absence of this flag, the message is only a warning. The message is issued if no SCCS identification keywords (see get) are found in the text retrieved or stored in the SCCS file. If a value is supplied, the application shall ensure that the keywords exactly match the given string; however, the string shall contain a keyword, and no embedded <newline> characters.
- Allow concurrent get commands for editing on the same SID of an SCCS file. This allows multiple concurrent updates to the same version of the SCCS file.
- Specify a list of releases to which deltas can no longer be made (that is, get -e against one of these locked releases fails). Conforming applications shall use the following syntax to specify a list. Implementations may accept additional forms as an extension:
<list> ::= a | <range-list> <range-list> ::= <range> | <range-list>, <range> <range> ::= <SID>
The character a in the list shall be equivalent to specifying all releases for the named SCCS file. The non-terminal <SID> in range shall be the delta number of an existing delta associated with the SCCS file.
- Cause delta 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 n flag may be ignored; that is, if the -r 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.
- Substitute user-definable text for all occurrences of the %Q% keyword in the SCCS file text retrieved by get.
- Specify the module name of the SCCS file substituted for all occurrences of the %M% keyword in the SCCS file text retrieved by get. If the m flag is not specified, the value assigned shall be the name of the SCCS file with the leading '.' removed.
- Specify the type of module in the SCCS file substituted for all occurrences of the %Y% keyword in the SCCS file text retrieved by get.
- Cause delta to prompt for modification request (MR) numbers as the reason for creating a delta. The optional value specifies the name of an MR number validation program. (If this flag is set when creating an SCCS file, the application shall ensure that the m option is also used even if its value is null.)
- -d flag
- Remove (delete) the specified flag from an SCCS file. Several -d options may be supplied on a single admin command. See the -f option for allowable flag names. (The llist flag gives a list of releases to be unlocked. See the -f option for further description of the l flag and the syntax of a list.)
- -a login
- Specify a login name, or numerical group ID, to be added to the list of users who may make deltas (changes) to the SCCS file. A group ID shall be equivalent to specifying all login names common to that group ID. Several -a options may be used on a single admin command line. As many logins, or numerical group IDs, as desired may be on the list simultaneously. If the list of users is empty, then anyone may add deltas. If login or group ID is preceded by a '!', the users so specified shall be denied permission to make deltas.
- -e login
- Specify a login name, or numerical group ID, to be erased from the list of users allowed to make deltas (changes) to the SCCS file. Specifying a group ID is equivalent to specifying all login names common to that group ID. Several -e options may be used on a single admin command line.
- Insert the comment text into the SCCS file as a comment for the initial delta in a manner identical to that of delta. In the POSIX locale, omission of the -y option shall result in a default comment line being inserted in the form:
"date and time created %s %s by %s", <date>, <time>, <login>
where <date> is expressed in the format of the date utility's %y/%m/%d conversion specification, <time> in the format of the date utility's %T conversion specification format, and <login> is the login name of the user creating the file.
- -m mrlist
- Insert the list of modification request (MR) numbers into the SCCS file as the reason for creating the initial delta in a manner identical to delta. The application shall ensure that the v flag is set and the MR numbers are validated if the v flag has a value (the name of an MR number validation program). A diagnostic message shall be written if the v flag is not set or MR validation fails.
- Check the structure of the SCCS file and compare the newly computed checksum with the checksum that is stored in the SCCS file. If the newly computed checksum does not match the checksum in the SCCS file, a diagnostic message shall be written.
- Recompute the SCCS file checksum and store it in the first line of the SCCS file (see the -h option above). Note that use of this option on a truly corrupted file may prevent future detection of the corruption.
- A pathname of an existing SCCS file or a directory. If file is a directory, the admin 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 s.) and unreadable files shall be silently ignored.
- A pathname of an SCCS file to be created.
If exactly one file or newfile operand appears, and it is '-', the standard input shall be read; each 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.
The application shall ensure that the file named by the -i option's name 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.
- Provide a default value for the internationalization variables that are unset or null. (See the Base Definitions volume of POSIX.1‐2017, Section 8.2, Internationalization Variables for the precedence of internationalization variables used to determine the values of locale categories.)
- If set to a non-empty string value, override the values of all the other internationalization variables.
- 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).
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 -y comment.
- Determine the location of message catalogs for the processing of LC_MESSAGES.
- Successful completion.
- An error occurred.
