and script


#!/bin/ksh


for i in DBSyncControllerRerun Archiver1 DBSyncListener Archiver2 Cleaner1 Interpolation
do
a=0
a=`date +"%h %d"`
ps -aef | grep java | grep $a | grep $i >> dates
done
---------------------------------------------------------------------
all the dates and time in the process are the startup time of those process.
Actually i want to grep those process according to their above mentioned dates and time.
but this script not working .its showing the o/p as:

grep: can't open 11
grep: can't open 11
grep: can't open 11
grep: can't open 11
grep: can't open 11
grep: can't open 11
---------------------------------------------------------------------

how to grep date and time in this case................

Change

grep $a

to

grep "$a"

in this case the o/p is
