SACT(1P)                   POSIX Programmer's Manual                  SACT(1P)

PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the corresponding
       Linux manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

NAME
       sact -- print current SCCS file-editing activity (DEVELOPMENT)

SYNOPSIS
       sact file...

DESCRIPTION
       The sact utility shall inform the user of any impending deltas to a
       named SCCS file by writing a list to standard output. This situation
       occurs when get -e has been executed previously without a subsequent
       execution of delta, unget, or sccs unedit.

OPTIONS
       None.

OPERANDS
       The following operand shall be supported:

       file      A pathname of an existing SCCS file or a directory. If file
                 is a directory, the sact 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.

                 If exactly one file 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.

STDIN
       The standard input shall be a text file used only when the file operand
       is specified as '-'.  Each line of the text file shall be interpreted
       as an SCCS pathname.

INPUT FILES
       Any SCCS files interrogated are files of an unspecified format.

ENVIRONMENT VARIABLES
       The following environment variables shall affect the execution of sact:

       LANG      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.)

       LC_ALL    If set to a non-empty string value, override the values of
                 all the other internationalization variables.

       LC_CTYPE  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).

       LC_MESSAGES
                 Determine the locale that should be used to affect the format
                 and contents of diagnostic messages written to standard
                 error.

       NLSPATH   Determine the location of message catalogs for the processing
                 of LC_MESSAGES.

ASYNCHRONOUS EVENTS
       Default.

STDOUT
       The output for each named file shall consist of a line in the following
       format:


           "%s %s %s %s %s\n", <SID>, <new SID>, <login>, <date>, <time>

       <SID>     Specifies the SID of a delta that currently exists in the
                 SCCS file to which changes are made to make the new delta.

       <new SID> Specifies the SID for the new delta to be created.

       <login>   Contains the login name of the user who makes the delta (that
                 is, who executed a get for editing).

       <date>    Contains the date that get -e was executed, in the format
                 used by the prs :D: data keyword.

       <time>    Contains the time that get -e was executed, in the format
                 used by the prs :T: data keyword.

       If there is more than one named file or if a directory or standard
       input is named, each pathname shall be written before each of the
       preceding lines:


           "\n%s:\n", <pathname>

STDERR
       The standard error shall be used only for optional informative messages
       concerning SCCS files with no impending deltas, and for diagnostic
       messages.

OUTPUT FILES
       None.

EXTENDED DESCRIPTION
       None.

EXIT STATUS
       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.

CONSEQUENCES OF ERRORS
       Default.

       The following sections are informative.

APPLICATION USAGE
       None.

EXAMPLES
       None.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
