Hi,

x=GATE

ps -ef|grep pmon
grid       552     1  0 Aug08 ?        00:00:51 asm_pmon_+ASM1
oracle    4314     1  0 Aug08 ?        00:04:08 ora_pmon_GATE1
oracle    5018  1351  0 10:14 pts/1    00:00:00 grep pmon
oracle    7329     1  0 Aug08 ?        00:02:19 ora_pmon_NRID1

ps -ef|grep pmon |grep $x
oracle    4314     1  0 Aug08 ?        00:04:08 ora_pmon_GATE1

but i want the result if it contains only GATE but not the GATE1

-Thanks,

try using grep $x$ if you are expecting GATE at the end of line..

Belt and braces:

ps -fuoracle | grep -v "grep" | grep "pmon" | grep "GATE" | grep-v "GATE1"

It would be better as:

ps -fuoracle | grep -v "grep" | grep "ora_pmon_GATE" | grep -v "ora_pmon_GATE1"

Maybe consider changing the name of each listener?

I suggest you consult the man page of "grep", especially the meaning of the "-w" switch (word boundaries).

I hope this helps.
