  13. .SH SYNOPSIS
  14. .LP
  15. .nf
  16. rmdel -r \fISID file\fR...
  17. .fi
  18. .SH DESCRIPTION
  19. The
  20. .IR rmdel
  21. utility shall remove the delta specified by the SID from each named
  22. SCCS file. The delta to be removed shall be the most recent delta in
  23. its branch in the delta chain of each named SCCS file. In addition, the
  24. application shall ensure that the SID specified is not that of a
  25. version being edited for the purpose of making a delta; that is, if a
  26. .IR p-file
  27. (see
  28. .IR "\fIget\fR\^")
  29. exists for the named SCCS file, the SID specified shall not appear in
  30. any entry of the
  31. .IR p-file .
  32. .P
  33. Removal of a delta shall be restricted to:
  34. .IP " 1." 4
  35. The user who made the delta
  36. .IP " 2." 4
  37. The owner of the SCCS file
  38. .IP " 3." 4
  39. The owner of the directory containing the SCCS file
  40. .SH OPTIONS
  41. The
  42. .IR rmdel
  43. utility shall conform to the Base Definitions volume of POSIX.1\(hy2017,
  44. .IR "Section 12.2" ", " "Utility Syntax Guidelines".
  45. .P
  46. The following option shall be supported:
  47. .IP "\fB\-r\ \fISID\fR" 10
  48. Specify the SCCS identification string (\c
  49. .IR SID )
  50. of the delta to be deleted.
  51. .SH OPERANDS
  52. The following operand shall be supported:
  53. .IP "\fIfile\fR" 10
  54. A pathname of an existing SCCS file or a directory. If
  55. .IR file
  56. is a directory, the
  57. .IR rmdel
  58. utility shall behave as though each file in the directory were
  59. specified as a named file, except that non-SCCS files (last component
  60. of the pathname does not begin with
  61. .BR s. )
  62. and unreadable files shall be silently ignored.
  63. .RS 10
  64. .P
  65. If exactly one
  66. .IR file
  67. operand appears, and it is
  68. .BR '\-' ,
  69. the standard input shall be read; each line of the standard input is
  70. taken to be the name of an SCCS file to be processed. Non-SCCS files
  71. and unreadable files shall be silently ignored.
  72. .RE
  73. .SH STDIN
  74. The standard input shall be a text file used only when the
  75. .IR file
  76. operand is specified as
  77. .BR '\-' .
  78. Each line of the text file shall be interpreted as an SCCS pathname.
  79. .SH "INPUT FILES"
  80. The SCCS files shall be files of unspecified format.
  81. .SH "ENVIRONMENT VARIABLES"
  82. The following environment variables shall affect the execution of
  83. .IR rmdel :
  84. .IP "\fILANG\fP" 10
  85. Provide a default value for the internationalization variables that are
  86. unset or null. (See the Base Definitions volume of POSIX.1\(hy2017,
  87. .IR "Section 8.2" ", " "Internationalization Variables"
  88. for the precedence of internationalization variables used to determine
  89. the values of locale categories.)
  90. .IP "\fILC_ALL\fP" 10
  91. If set to a non-empty string value, override the values of all the
  92. other internationalization variables.
  93. .IP "\fILC_CTYPE\fP" 10
  94. Determine the locale for the interpretation of sequences of bytes of
  95. text data as characters (for example, single-byte as opposed to
  96. multi-byte characters in arguments and input files).
  97. .IP "\fILC_MESSAGES\fP" 10
  98. .br
  99. Determine the locale that should be used to affect the format and
  100. contents of diagnostic messages written to standard error.
  101. .IP "\fINLSPATH\fP" 10
  102. Determine the location of message catalogs for the processing of
  103. .IR LC_MESSAGES .
  104. .SH "ASYNCHRONOUS EVENTS"
  105. Default.
  106. .SH STDOUT
  107. Not used.
  108. .SH STDERR
  109. The standard error shall be used only for diagnostic messages.
  110. .SH "OUTPUT FILES"
  111. The SCCS files shall be files of unspecified format. During processing
  112. of a
  113. .IR file ,
  114. a temporary
  115. .IR x-file ,
  116. as described in
  117. .IR "\fIadmin\fR\^",
  118. may be created and deleted; a locking
  119. .IR z-file ,
  120. as described in
  121. .IR "\fIget\fR\^",
  122. may be created and deleted.
  123. .SH "EXTENDED DESCRIPTION"
  124. None.
  125. .SH "EXIT STATUS"
  126. The following exit values shall be returned:
  127. .IP "\00" 6
  128. Successful completion.
  129. .IP >0 6
  130. An error occurred.
  131. .SH "CONSEQUENCES OF ERRORS"
  132. Default.
