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.1-2008, 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.
