EXAMPLES

        rule    // get log file size, in lines for text files, and KB for
                // binary files
                set #size = #if(#binary, #filesize($name)/=KB,
                                         #val($command("=wc -l $name | =awk '{print \$1}'")))

#if solaris

proc_count(P)   // return the process count for process (P)
                // (P) is the process name (without quotes, e.g., =inetd)
                // sample usage:  if =proc_count(=inetd) > 1
                #value($command("=ps -eo comm | grep -c (P)"))
