Help with function
Hi I'm a newbie in unix scripting and I'm trying to do a function that do the next:

Run this command: opcdeploy -cmd "utility -xs" -node node.com and store the result in a file.
Get the last ten lines from the stored file and do a search for the number 100, store that search in a variable.
If the result of that search is greater or equal than 100 then echo "hello"; else echo "bye".
Here is what I have done:

Code:
function utility {
opcdeploy -cmd "utility -xs" -node $SERVER | tail -10 > /home/oscar/Desktop/tail.util

let Z=100
let Y=`grep $Z /home/oscar/Desktop/tail.util`


if [ $Y -ge $Z ];then
    echo "hello"
  else
    echo "bye"
fi
}

please can someone help me to improve this, what I have done wrong?

thanks!

Grep for "100" will not find most values greater than 100 (eg 372, 2000, etc).
What does the output look like, and what value are you wanting to compare with 100?

Thanks, the opcdeploy output is:

Code:
The Global      file is now  76.3% full with room for  15.0 more full days
The Application file is now  91.6% full with room for   8.7 more full days
The Process     file is now  98.4% full with room for   0.7 more full days
The Device      file is now  80.1% full with room for   3.3 more full days
The Transaction file is now 100.7% full with room for   0.0 more full days

So I want to get the % number and compare it, for example:

Get this number 76.3 and put it into a variable to compare(-ge) it with the number 100; then
echo bla bla bla

else
echo bla bla bla

fi

Hi!
Why would you need a comparison?
If you can read 100, you have at least 100. So if you can read 100, you're done.

Hint:
Code:
 ( (egrep -q  "100\.*[0-9]*\%" /home/oscar/Desktop/tail.util ) && echo hello ) || echo bye

If you run your script frequently enough, you'll catch greater values in time (which I though was your goal).

However:

Code:
 ( (egrep -q  "[1-9][0-9]{2,}\.*[0-9]*\%" /home/oscar/Desktop/tail.util ) && echo hello ) || echo bye

will match every percent number greater or equal than 100%.

Thank you Lem I tried this:

Code:
egrep -q  "[1-9][0-9]{2,}\.*[0-9]*\%" /home/oscar/Desktop/tail.util

but it didnt display any output, insted of that I tried this:

Code:
sed "s/[^0-9]//g;s/^$/-1/;" /home/oscar/Desktop/tail.util

and got this output for example for the first ovcodautil line:
Code:
"The Global      file is now  76.3% full with room for  15.0 more full days"

the output was 763150, but I need only the first three as they are on the line(76.3), any idea?
