The problem with this is that you are asking if "cat database.txt" is exactly "ERROR", which of course it isn't. For tasks like yours, where you want to know if a text contains a certain string there is a Unix command named "grep". Have a look at the man page for grep to find out what you could do with it (which is quite a lot, i can assure you).

Your code should look like:

Code:

if [ $(grep -c "ERROR" database.txt) = 0 ]; then
     print - "no error found"
else
     print - "error found"
fi

Similar for "WARNING", etc..

I hope this helps (and you don't forget your code-tags from now on ;-) ).
