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
	      IEEE Std 1003.1-2001, Section  8.2,  Internationalization	 Vari‐
	      ables  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 pre‐
       ceding 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 mes‐
       sages.

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.
