#### NAME

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

#### SYNOPSIS

> ``[XSI] 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 XBD 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.

#### SEE ALSO

> delta, get, sccs, unget

> XBD Environment Variables

#### CHANGE HISTORY

> First released in Issue 2.
