Computer Get value from file!!!!
Hi,
I'm trying to get the value of load average from the file /proc/loadavg to my script. I'm a bit new to scripting. I need to get the value as an integer type to do a checking. Can anyone help me on what to do to get the value of the current load average into the script?

Please include a sample of the file so people can offer you a solution.

Computer Sample
I get the load average like this

gawk '{ load=$1 }' /proc/loadavg

Now i need to check whether if its greater than 10 and if so stop my apache server.

Jibu,
I meant a sample of the actual input file "/proc/loadavg".
If your file has only one number per record, see if this would work for you:
Code:
while read Inbr
do
  echo $Inbr
  if [ ${Inbr} -gt 77 ]; then
    echo "Greater than 77"
  else
    echo "Less or equal to 77"
  fi
done < /proc/loadavg

I'm trying to do the check like this.......


uptime|gawk -F" " '{ print $8 }' > load
while read Inbr
do
echo $Inbr
if [ ${Inbr} -gt 77 ]; then
echo "Greater than 77"
else
echo "Less or equal to 77"
fi
done < load

but i get an error


line 7: [: 0.84: integer expression expected

How can i convert the inout from file load to integer???

Jibu,
I still don't understand what you want to accomplish.
Lets start from scratch.
The output of the command "uptime" will give you the following:
Code:
 3:09pm  up 31 day(s), 14:02,  7 users,  load average: 0.07, 0.07, 0.08

Which field do you want to compare?

Hi,
I want to compare the value 0.07, the current load average

3:09pm up 31 day(s), 14:02, 7 users, load average: 0.07, 0.07, 0.08
