Hit count: 132
My problematic code:
testMYSQL=`mysql -u $mysqlUser -p$mysqlPass -h $mysqlHost --skip-column-names --batch -D $mysqlDB -e "SELECT $select FROM $mysqlTable WHERE nameTXT='test';"`
$testMYSQL now contains:
test
test
test
Then I do:
TEST=$(echo $testMYSQL | wc -l)
echo "$TEST"
I would of thought that would work, but it doesn't, it returns 1
But if I put this into $testMYSQL: "test\ntest\ntest" it will say 3…
Whats going on here? does MYSQL not use new lines?
PS, I know I can use a for loop to loop though the lines then count up the lines that way, but I was hoping for a simpler solution like wc
