Re: help with shell scripting!!

You need to give arguments the test command will recognises,
such -n string, properly quote the arguments, and you should space
the brackets. In bourne shell it would look like
if [ -n "`echo $y | grep errors`" ]
then
echo "errors found"
fi

Or, bypass the test operation completely and use the exit code of
grep to indicate whether the string was found:

if echo "$y" | grep errors > /dev/null
then
echo "errors found"
fi

Or use the expr command:

if expr "$y" : '.*errors' > /dev/null
then
echo "errors found"
fi

Or, as someone else said, use a case statement (the most efficient way).
