       This manual page is part of the POSIX Programmer's Manual.  The OS
       implementation of this interface may differ (consult the corresponding
       OS manual page for details of OS behavior), or the interface may not be
       implemented on OS.

DDEESSCCRRIIPPTTIIOONN
       The _s_a_c_t 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 _g_e_t --ee has been executed previously without a subsequent
       execution of _d_e_l_t_a, _u_n_g_e_t, or _s_c_c_s uunneeddiitt.

OOPPTTIIOONNSS
       None.

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 _s_a_c_t 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
                 shall be 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
       Any SCCS files interrogated are files of an unspecified format.

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

       _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
       The output for each named file shall consist of a line in the following
       format:


           "%s %s %s %s %s\n", <_S_I_D>, <_n_e_w _S_I_D>, <_l_o_g_i_n>, <_d_a_t_e>, <_t_i_m_e>

       <_S_I_D>     Specifies the SID of a delta that currently exists in the
                 SCCS file to which changes are made to make the new delta.

       <_n_e_w _S_I_D> Specifies the SID for the new delta to be created.

       <_l_o_g_i_n>   Contains the login name of the user who makes the delta (that
                 is, who executed a _g_e_t for editing).

       <_d_a_t_e>    Contains the date that _g_e_t --ee was executed, in the format
                 used by the _p_r_s ::DD:: data keyword.

       <_t_i_m_e>    Contains the time that _g_e_t --ee was executed, in the format
                 used by the _p_r_s ::TT:: 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", <_p_a_t_h_n_a_m_e>

SSTTDDEERRRR
       The standard error shall be used only for optional informative messages
       concerning SCCS files with no impending deltas, and for diagnostic
       messages.

OOUUTTPPUUTT FFIILLEESS
       None.

       The following exit values shall be returned:
