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.
NAMEsact — print current SCCS file-editing activity (DEVELOPMENT)
SYNOPSISsact 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 stan‐
dard input shall be read; each line of the standard input
shall be taken to be the name of an SCCS file to be pro‐
cessed. 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 vari‐
ables that are unset or null. (See the Base Definitions vol‐
ume of POSIX.1‐2008, 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.
