Script that echo 0 if a process(parameter) is not running.

[Larshg]

Hi

I trying to make a script that echo 1, if the process that is given to it, is not running. - just a ps command
ps -ef|grep "parameter"
The problem is that I need to give it several parameters
ps -ef|grep "parameter1" |grep "parameter2"


this ex. has 2 parameters
ProcessExists.ksh "test" "test 2" - the ps command should then be something like this
ps -ef|grep "test" |grep "test 2"


I've tryede to make a script that runs throu the parameters - but I can't get them to echo out the parameter.



#!/bin/ksh

i=0
Item=1

while [ $i -lt $# ]
do

echo $Item " Item"

parm="$"$Item;echo `echo $parm`
echo $$Item

(( Item=$Item+1 ))
i=$((1+i))

done

Something like this ?
#!/bin/ksh
: ProcessExists.ksh process1 [process2 ...]
[ $# -ge 1 ] || exit 1
nbSearch=$#
search="$1"; shift
for i; do search="${search}|$i"; done
[ $(ps -fe | grep -cE "$search") -lt $nbSearch ] && echo 1

Hope This Help, PH.

I'm not quite sure I understand what you do.

you go throu the parameters and putting | between them - ending up with something looking like this.
ProcessExists.ksh process1 process2
process1|process2
Then you do a ps -ef|grep -cE "process1|process2"

I can't realy figure out what this does, but it does not do tha same as
ps -ef|grep process1|grep process2
(I want to find the processes that contains process1 and process2)

Another ting is that the script should handel spaces
ex
ProcessExists.ksh "process 1" "process2"
should only pick the first of these processes - not the last one
root 479 1 0 Jan 9 ? 0:00 process 1 process2
root 480 479 0 Jan 9 ? 29:52 process1 process2

like with
ps -ef|grep "process 1" |grep "process2"


Thanks

Sorry for the misunderstanding.
The above script should echo 0 if process not found:
[ $# -ge 1 ] || exit 1
search="$1"; shift
for i; do search="${search}|$i"; done
ps -fe | awk -v search="$search" '
BEGIN{n=split(search,s,"|")}
{for(i=1;i<=n;++n)if($0!~s)next;exit}
END{print 0}'

This works on Sun/ksh. It returns 0/1 rather than echo but is easy enough to change...

#! /usr/bin/ksh

SEARCH=`ps -ef | grep -v "ps -ef" | grep -v "${0} ${1}` >> /dev/null

while [ $# -gt 0 ]
do
echo ${SEARCH} | grep "${1}" >> /dev/null
if [ $? -ne 0 ]
then
exit 1
fi
echo ${1}
SEARCH=`echo ${SEARCH} | grep "${1}"`
shift
done
exit 0
