I just want to return the line available in FILE1 but not FILE2 in
diff. After I read the document, it seems that this is not possible.
Could anybody confirm whether this is true? If so, is there an
alternative tool that does this? Thanks!

Perhaps you want comm instead of diff:
comm -23 FILE

I meant:
comm -23 FILE1 FILE2

Using diff will show removed lines with a "-"; otherwise, consider
using the comm utility since that might be closer to what you want...
% cat > FILE1
This is a test
file.
% tail -4 FILE1 >! FILE2 % diff -bdu FILE1 FILE2
--- FILE1 2012-11-12 16:37:45.000000000 -0800

That only works if the files are both sorted.

You might consider that -u may take an optional number of context
lines to display.
`-U LINES'
`--unified[=LINES]'
Use the unified output format, showing LINES (an integer) lines of
context, or three if LINES is not given. *Note Unified Format::.
For proper operation, `patch' typically needs at least two lines of
context.
