Indeed. As far as I know the term, an interpreter is something which
reads text from a file, parses it an checks it for syntax errors
and then executes the code as soon as enough of it has been gathered to
allow for execution of something, ie, a complete statement. This read,
check and parse, execute cycle is repeated until the program
terminates.

Example for this:

[rw@doppelsaurus]/tmp#cat a.sh
ed a.sh <<'TT' >/dev/null 2>&1
9,$d
wq
TT
echo `expr $i + 0`
i=`expr $i + 1`
test $i = 11 && exit
sed -n '5,8p' a.sh | tee -a a.sh >/dev/null

This is a script printing the numbers from 0 to 10 by exploiting
the property that /bin/sh is an interpeter.

In contrast to this, a compiler reads the source code completely, parses
and checks it and then transforms it into some sort of "other
representation" which can be executed without dealing with the source
code (text) again. Eg, the Java compiler transforms Java source code
into Java bytecode which is then usually executed by the jvm. OTOH,
processors capable of executing Java bytecode directly exit or at least
used to exist. ARM CPUs once had an extension for that (Jazelle).
