aapid for business monitoring ID

#/bin/sh
Onl_ok=1
Onl_cored=3
Dir=/usr/local/script
if [[!-F "$dir/old.txt"]];then
PS aux|grep aapid |grep-v grep|grep-v/bin/bash|awk ' {print $2,$11} ' > $dir/old.txt
Else

Fi
PS aux|grep aapid |grep-v grep|grep-v/bin/bash|awk ' {print $2,$11} ' > $dir/now.txt
if! Diff-q $dir/old.txt $dir/now.txt >/dev/null; Then
Echo $onl _cored
Diff-c $dir/old.txt $dir/now.txt > $dir/' Date ' +%y%m%d%h%m "' _diff.txt
Cat $dir/now.txt > $dir/old.txt
