Restart Inetd

sighup_inetd_programs.cfg specifies a simple stand-alone Pikt script to restart inetd.  Note how the #if directive customizes the script for different operating systems.

#if solaris

#elif linux
                           "=ps -xc | =grep inetd | =grep -v grep"
#endif
                dat $inetdpid  1        // 'pid' is a reserved var name
                dat $inetdproc $        // unused
        
        rule
                =exec "=kill -HUP $inetdpid"

On the piktmaster system, we would install the SigHupInetd.pkt script to each PIKT slave system with the command:

# piktc -iv +P SigHupInetd.pkt +H all        [or: ... -H down]
