or the interface may not be implemented on Linux.
Имя (Name)
sact — print current SCCS file-editing activity (DEVELOPMENT)
Синопсис (Synopsis)
sact file...
Описание (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.
Параметры (Options)
None.
Операнды (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.
Стандартный ввод (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.
Входные файлы (Input files)
Any SCCS files interrogated are files of an unspecified format.
Переменные окружения (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.
Асинхронные события (Asynchronous events)
Default.
Стандартный вывод (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>
Стандартный вывод сообщений (Stderr)
The standard error shall be used only for optional informative
messages concerning SCCS files with no impending deltas, and for
diagnostic messages.
Выходные файлы (Output files)
None.
Расширенное описание (Extended description)
None.
Статус выхода (Exit)
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred.
Последствия ошибок (Consequences of errors)
Default.
The following sections are informative.
Использование в приложениях (Application usage)
None.
Примеры (Examples)
None.
Обоснование (Rationale)
None.
Будущие направления (Future directions)
None.
