NAME

sccs - Administration program for Source Code Control System (SCCS) commands  

SYNOPSIS

sccs [-r] [-d pathname] [-p pathname] command [command-opts...] [parameters...]


 

OPTIONS

Specifies a root directory for the SCCS files. The default is the current directory. The pathname argument is prepended to the entire path name of a file. This option takes precedence over the PROJECTDIR variable. Specifies a path name for the SCCS files. The default is the SCCS directory.

The pathname argument associated with the -d option is inserted before the entire path name. The pathname argument associated with the -p option is inserted before the final component of the path name. For example, the command sccs -d/x -py get a/b converts to get /x/a/y/s.b.
This can be used to create aliases. See the first entry in the EXAMPLES section. Runs the sccs command as the real user, rather than as the effective user to which the sccs command is set. Certain commands (admin, check, clean, diffs, info, rmdel, sccsdiff, tell) 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.
 

OPERANDS

SCCS command or pseudocommand listed in the DESCRIPTION section to be executed. Options for the specified command or pseudocommand.

All options specified after command are passed to that command during execution. (For a description of command options, see the appropriate command description.) Parameters (usually file or directory path names) for the specified command or pseudocommand.
All parameters specified after command are passed to that command during execution. (For a description of command parameters, see the appropriate command description.)
 

DESCRIPTION

The sccs command is an administration program that incorporates the set of SCCS commands into the operating system.

[Compaq]  The sccs command can be used to assign or reassign file ownership.

The sccs command activates a specified command with the specified options and arguments. Each file is placed in a directory named SCCS and named s.filename. The directory SCCS is assumed to exist relative to the current directory (unless the -p option is used).

Two types of commands can be used in the sccs command syntax sentence.
 

SCCS Commands

The first type is the sccs commands that can be entered at a prompt. For a description of the command, options, and parameters, see the reference page with same name as the command. Function Creates and initializes or changes (administer) SCCS files. [Compaq]  Changes the comments in a Source Code Control System (SCCS) delta. [Compaq]  Combines Source Code Control System (SCCS) deltas. Saves editing changes in a Source Code Control System (SCCS) file. Creates a specified version of a Source Code Control System (SCCS) file. Displays key information in a Source Code Control System (SCCS) file. Removes a delta from a Source Code Control System (SCCS) file. Displays current Source Code Control System (SCCS) file editing status. [Compaq]  Compares two versions of a Source Code Control System (SCCS) file. [Compaq]  Provides information about a Source Code Control System (SCCS) message or command. Cancels a previous get command Validates Source Code Control System (SCCS) files. Displays identifying information for Source Code Control System (SCCS) files.
 

Pseudocommands

The second type is called pseudocommands; they can be used only as part of the sccs command syntax. These pseudocommands, the actions they perform, options and parameters are: Description Prints all the files being edited. Returns a nonzero exit status if a file is being edited. The check program puts the nonzero status indicator in an install entry in a makefile to verify that the SCCS file is complete before installing a version. Equivalent to info except that nothing is printed if nothing is being edited.

Options: Ignores branches in determining which files are being edited. Lists only the files being edited by you or the user named by user. Equivalent to specifying -u <your login name>. Removes from the current directory or the named directory all files that can be recreated from SCCS files. Does not remove files that are in the process of being edited.
Option: Ignores branches in determining which files are being edited. (Note: branches in the same directory can be lost.) Creates an SCCS file, copying the initial contents from a file of the same name. If the file creation is successful, the original file is renamed with a comma on the front. It is recommended, but not necessary, that you to move or remove the original file (as is the case with the admin command).
Options:
Accepts the same options as the admin command. See the admin(1) reference page. Performs a delta command on the named files and then gets a new version. The new version of the files has expanded identification keywords, and cannot be edited.
Options: Can be passed to the delta command. See the delta(1) reference page. Can be passed to the get command. See the get(1) reference page. Equivalent to the delget pseudocommand, except that the get portion of the sentence includes the -e option. The deledit option is useful for creating a checkpoint in your current editing session.
Options: Can be passed to the delta command. See the delta(1) reference page. Can be passed to the get command. See the get(1) reference page. Shows the difference between the current version of the files you are editing and the versions in SCCS format.
Options: Can be passed to the get command. See the get(1) reference page. Can be passed to the system diff (not SCCS) command. See the diff(1) reference page. Can be passed to the system diff (not SCCS) command as a -c option. See the diff(1) reference page. Equivalent to the get -e command. [Compaq]  Creates an SCCS file, copying the initial contents from a file of the same name. If the file creation is successful, the original file is renamed with a , (comma) at the beginning of the old file name. This pseudocommand is similar to create, except that enter does not perform the equivalent of an SCCS get command, and retrieves a read-only version of the newly created file. This pseudocommand is useful when you want to use an SCCS edit command immediately after creating an SCCS file. Removes a named delta, but leaves a copy of the delta with changes intact. This copy is useful for fixing small compilation errors. This command does not keep a record of changes made to the file. The fix command must include -r SID.
Option: Specifies the delta to be removed. Lists all the files being edited.
Options: Ignores branches in determining which files are being edited. Lists only the files being edited by you or the user named by user. Equivalent to specifying -u <your login name>. Prints information about named files. This SCCS pseudocommand is equivalent to the SCCS command prs. Lists, on standard output, all the files being edited, with a newline after each entry.
Options: Ignores branches in determining which files are being edited. Lists only the files being edited by you or the user named by user. Equivalent to specifying -u <your login name>. Equivalent to the unget command. Any changes made since the get command was used are lost.
 

RESTRICTIONS

[Compaq]  In some other versions of the utility, the command runs with the UID of a pseudo-user named sccs. This difference can create compatibility problems with permissions, especially in networked environments.
 

EXIT STATUS

The following exit values are returned: Successful completion. An error occurred.
 

EXAMPLES

Enter the command: alias syssccs sccs -d/usr/abc/sccs

This makes syssccs an alias that can be used in commands like: syssccs get cmd/who.c To get a file for editing, edit it, and produce a new delta, enter: $ sccs get -e file.c $ ex file.c $ sccs delta file.c To get a file from another directory, enter: sccs -p/usr/abc/sccs get cc.c To make a delta of a large number of files in the current directory, enter: sccs delta *.c To get a list of files being edited that are not on branches, enter: sccs info -b To make a delta of everything being edited by you, enter: sccs delta `sccs tell -u` In a makefile, to get source files from an SCCS file if it does not already exist, enter: REL = 1.7 SRCS = <list of source files> $(SRCS):
       sccs get $(REL) $@

 

ENVIRONMENT VARIABLES

The following environment variables affect the execution of sccs: Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization variables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value, overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments and input files). Determines the locale for the format and contents of diagnostic messages written to standard error. Determines the location of message catalogs for the processing of LC_MESSAGES. If this is set, its value is used to determine the -d option value. If PROJECTDIR begins with a / (slash), the value is used directly; otherwise, the home directory of a user of that name is examined for a subdirectory named src or source. If found, that subdirectory is used. The -d option takes precedence over this variable.
