At the moment, there are two processes and the code gives:
Code:
0.2
0.2
0.0
Normally 0.0 at the bottom line is the program itself. I am working on how to take/read all output lines excluding the bottom one or assigning pid value to search in the result.

A guess: You seem to want to terminate a process that doesn't do any work any more but doesn't quit. None of your commands in your code addresses that.
Yes, that's what I wish to do but you both say it's no good.
PS: At first, I could not have found any info regarding abbreviations, then coincidentally learnt the meaning of gt and lt
I am working on it..
Update:
Code:
ps aux | grep 'zoltan' | grep 'cvlc' | awk '{print $4}'
if [ $? -eq 0.0 ]; then
echo "vlc is not running"
./restart.sh
else
echo "vlc is okay"
fi
exit 0
Output:
Code:
0.2
0.2
./check.sh: line 2: [: 0.0: integer expression expected
vlc is okay
Latest:
Code:
ps aux | grep 'zoltan' | grep 'cvlc' | awk '{print $4}'
if [ $? -eq 0 ]; then
id=$(ps aux | grep 'zoltan' | grep 'cvlc' | awk '{print $2}')
echo "vlc is not running"
kill $id
./restart.sh
else
echo "vlc is okay"
fi
exit 0
Not-working process has been killed and restarted..
Sorted now:
Code:
ps aux | grep 'zoltan' | grep 'cvlc' | awk '{print $4}'
if [ $? -eq 0 ]; then
id=$(ps aux | grep 'zoltan' | grep 'cvlc' | awk '{print $2}')
echo "vlc is not running"
ps -f -u zoltan | awk '{ for(i=8; i<=NF; ++i) printf $i""FS; print "" }' > rerun
kill $id
sleep 2
sed -i '1d' rerun
chmod 755 rerun
sed -i "s|/usr/bin/vlc|sudo -u zoltan /usr/bin/vlc|g" rerun
sed -i "s|$| >> output.log 2>&1 < /dev/null \&|g" rerun
./rerun
else
echo "vlc is okay"
fi
exit 0
When cpu 0.0%, it restarts related process.. I am sure you can make it with shorter commands but works though.
