sact - print current SCCS file-editing activity (
DEVELOPMENT)
Návod, kniha: POSIX Programmer's Manual
sact file...
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.
None.
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.
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.
Any SCCS files interrogated are files of an unspecified format.
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
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 .
Default.
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:
The standard error shall be used only for optional informative messages
concerning SCCS files with no impending deltas, and for diagnostic messages.
None.
None.
The following exit values shall be returned:
- 0
- Successful completion.
- >0
- An error occurred.
Default.
The following sections are informative.
None.
None.
None.
None.
delta ,
get ,
sccs ,
unget
