So I'm new to the OS X terminal and I'm trying to figure out how to use the if command with the read command.
Like this:
echo stuff:
read f
if [ "f" == "y"]
then
echo wassup
else exit
What am I doing wrong?

You're asking bash to compare whether the strings f and y are equivalent. Clearly, they're not. You need to use a variable substitution:
if [ "$f" == "y" ]
With this, it's asking “is the string consisting of the contents of the variable f equivalent to the string y?”, which is probably what you were trying to do.
You're also missing an fi (if backwards), which ends the if statement. Together:
if [ "$f" == "y" ]
then
# true branch
else
# false branch
fi

@SpectrumCreations Also, note that you do not have a space before the closing
] in your original post; it's required.
