In a unix shell script(say do.ksh), I want to read a file called load_errors.log and count the word ORA- for the number of occurances.
If the occurance is more than 50, then I would like the unix shell script to exit with a message "ORA- found more than 50 times"

How can this be done ? Thanks

The following script assume that there is no more than one error per line:

Thank you. But the script that I want to include these lines is supposed to grep in another file for those words.
How do I specify the other file usage ?


Will this work:

if (( $(grep -c 'ORA-' load_errors.log ) > 50 ))
then
echo "ORA- found more than 50 times"
fi

This will work.
I have tested my script with stdin and forget to add the file name in my post.
