.SH NAME
|
|
rmdel \- remove a delta from an SCCS file (\fBDEVELOPMENT\fP)
|
|
.SH SYNOPSIS
|
|
.LP
|
|
\fBrmdel -r\fP \fISID file\fP\fB... \fP
|
|
.SH DESCRIPTION
|
|
.LP
|
|
The \fIrmdel\fP utility shall remove the delta specified by the SID
|
|
from each named SCCS file. The delta to be removed shall be
|
|
the most recent delta in its branch in the delta chain of each named
|
|
SCCS file. In addition, the application shall ensure that the
|
|
SID specified is not that of a version being edited for the purpose
|
|
of making a delta; that is, if a \fIp-file\fP (see \fIget\fP ) exists
|
|
for the named SCCS file, the SID specified shall not appear in any
|
|
entry of the
|
|
\fIp-file\fP.
|
|
.LP
|
|
Removal of a delta shall be restricted to:
|
|
.IP " 1." 4
|
|
The user who made the delta
|
|
.LP
|
|
.IP " 2." 4
|
|
The owner of the SCCS file
|
|
.LP
|
|
.IP " 3." 4
|
|
The owner of the directory containing the SCCS file
|
|
.LP
|
|
.SH OPTIONS
|
|
.LP
|
|
The \fIrmdel\fP utility shall conform to the Base Definitions volume
|
|
of IEEE\ Std\ 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
|
|
.LP
|
|
The following option shall be supported:
|
|
.TP 7
|
|
\fB-r\ \fP \fISID\fP
|
|
Specify the SCCS identification string ( \fISID\fP) of the delta to
|
|
be deleted.
|
|
.sp
|
|
.SH OPERANDS
|
|
.LP
|
|
The following operand shall be supported:
|
|
.TP 7
|
|
\fIfile\fP
|
|
A pathname of an existing SCCS file or a directory. If \fIfile\fP
|
|
is a directory, the \fIrmdel\fP 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 \fBs.\fP) and unreadable files shall be silently ignored.
|
|
.LP
|
|
If exactly one \fIfile\fP operand appears, and it is \fB'-'\fP , the
|
|
standard input shall be read; each line of the standard
|
|
input is taken to be the name of an SCCS file to be processed. Non-SCCS
|
|
files and unreadable files shall be silently ignored.
|
|
.sp
|
|
.SH STDIN
|
|
.LP
|
|
The standard input shall be a text file used only when the \fIfile\fP
|
|
operand is specified as \fB'-'\fP . Each line of the
|
|
text file shall be interpreted as an SCCS pathname.
|
|
.SH INPUT FILES
|
|
.LP
|
|
The SCCS files shall be files of unspecified format.
|
|
.SH ENVIRONMENT VARIABLES
|
|
.LP
|
|
The following environment variables shall affect the execution of
|
|
\fIrmdel\fP:
|
|
.TP 7
|
|
\fILANG\fP
|
|
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.)
|
|
.TP 7
|
|
\fILC_ALL\fP
|
|
If set to a non-empty string value, override the values of all the
|
|
other internationalization variables.
|
|
.TP 7
|
|
\fILC_CTYPE\fP
|
|
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).
|
|
.TP 7
|
|
\fILC_MESSAGES\fP
|
|
Determine the locale that should be used to affect the format and
|
|
contents of diagnostic messages written to standard
|
|
error.
|
|
.TP 7
|
|
\fINLSPATH\fP
|
|
Determine the location of message catalogs for the processing of \fILC_MESSAGES
|
|
\&.\fP

|
.sp
|
|
.SH ASYNCHRONOUS EVENTS
|
|
.LP
|
|

|
.SH STDOUT
|
|
.LP

|
|
.SH STDERR
|
|
.LP
|
|
The standard error shall be used only for diagnostic messages.
|
|
.SH OUTPUT FILES
|
|
.LP
|
|
The SCCS files shall be files of unspecified format. During processing
|
|
of a \fIfile\fP, a temporary \fIx-file\fP, as described
|
|
in \fIadmin\fP , may be created and deleted; a locking \fIz-file\fP,
|
|
as described in \fIget\fP , may be created and deleted.
