HAVE_MAIL(SIPB)     UNIX Programmer's Manual      HAVE_MAIL(SIPB)



NAME
     have_mail - tell whether a user has mail

SYNOPSYS
     have_mail [user_name]

DESCRIPTION
     Checks for a file in /usr/spool/mail beloning to the speci-
     fied user (defaulting to the user invoking the command) and
     determines whether the file is non-empty.  This is similar
     to the mechanism by which _l_o_g_i_n finds out if a user has
     mail.

     If the output is not directed to a terminal, the value is
     returned as 0 or 1, so that "`_h_a_v_e__m_a_i_l`" may be used in a
     shell script, i.e., "if (`_h_a_v_e__m_a_i_l`) then inc".  Otherwise,
     it is in the format "You have mail." or "User spook has
     mail."

FILES
     /usr/spool/mail/*

BUGS
     When executed as a remote shell, the short form of the out-
     put is invoked.  It should be made a control argument.
