       This manual page is part of the POSIX Programmer's Manual.  The OS

       rmdel -- remove a delta from an SCCS file (DDEEVVEELLOOPPMMEENNTT)

SSYYNNOOPPSSIISS
       rmdel -r _S_I_D _f_i_l_e...

DDEESSCCRRIIPPTTIIOONN
       The _r_m_d_e_l 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
       _p_-_f_i_l_e (see _g_e_t) exists for the named SCCS file, the SID specified
       shall not appear in any entry of the _p_-_f_i_l_e.

       Removal of a delta shall be restricted to:

        1. The user who made the delta

        2. The owner of the SCCS file

        3. The owner of the directory containing the SCCS file

OOPPTTIIOONNSS
       The _r_m_d_e_l utility shall conform to the Base Definitions volume of
       POSIX.1-2017, _S_e_c_t_i_o_n _1_2_._2, _U_t_i_l_i_t_y _S_y_n_t_a_x _G_u_i_d_e_l_i_n_e_s.

       The following option shall be supported:

       --rr _S_I_D    Specify the SCCS identification string (_S_I_D) of the delta to
                 be deleted.

OOPPEERRAANNDDSS
       The following operand shall be supported:

       _f_i_l_e      A pathname of an existing SCCS file or a directory. If _f_i_l_e
                 is a directory, the _r_m_d_e_l 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 ss..)  and unreadable files shall be silently
                 ignored.

                 If exactly one _f_i_l_e operand appears, and it is ''--'', 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.

SSTTDDIINN
       The standard input shall be a text file used only when the _f_i_l_e operand
       is specified as ''--''.  Each line of the text file shall be interpreted
       as an SCCS pathname.

IINNPPUUTT FFIILLEESS
       The SCCS files shall be files of unspecified format.

EENNVVIIRROONNMMEENNTT VVAARRIIAABBLLEESS
       The following environment variables shall affect the execution of
       _r_m_d_e_l:

       _L_A_N_G      Provide a default value for the internationalization
                 variables that are unset or null. (See the Base Definitions
                 volume of POSIX.1-2017, _S_e_c_t_i_o_n _8_._2, _I_n_t_e_r_n_a_t_i_o_n_a_l_i_z_a_t_i_o_n
                 _V_a_r_i_a_b_l_e_s for the precedence of internationalization
                 variables used to determine the values of locale categories.)

       _L_C___A_L_L    If set to a non-empty string value, override the values of
                 all the other internationalization variables.

       _L_C___C_T_Y_P_E  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).

       _L_C___M_E_S_S_A_G_E_S
                 Determine the locale that should be used to affect the format
                 and contents of diagnostic messages written to standard
                 error.

       _N_L_S_P_A_T_H   Determine the location of message catalogs for the processing
                 of _L_C___M_E_S_S_A_G_E_S.

AASSYYNNCCHHRROONNOOUUSS EEVVEENNTTSS
       Default.

SSTTDDOOUUTT
       Not used.

SSTTDDEERRRR
       The standard error shall be used only for diagnostic messages.

OOUUTTPPUUTT FFIILLEESS
       The SCCS files shall be files of unspecified format. During processing
       of a _f_i_l_e, a temporary _x_-_f_i_l_e, as described in _a_d_m_i_n, may be created
       and deleted; a locking _z_-_f_i_l_e, as described in _g_e_t, may be created and
       deleted.

EEXXTTEENNDDEEDD DDEESSCCRRIIPPTTIIOONN
       None.

EEXXIITT SSTTAATTUUSS
       The following exit values shall be returned:
