It can be seen as "evaluation symbol" (as known from $FOO
being "FOO evaluated"), or "value of" ($FOO = the value
Another way (convenient, but doesn't look good" is to do
something like this:
This is a newline as well. In the case above, you want to
set IFS to an _actual_ newline, not to \n. Remember _when_
the shell evaluates something: Variables like $IFS will
be evaluated when being accessed, not when they are being
declared (even with an initial value). The $'\n' makes
sure that IFS will be assigned an actual (non-escaped)
newline, so when constructs like for() or while read
access $IFS, they find a "real" newline there.
With the same idea in mind, you sometimes find things
I think it becomes perfectly clear now: IFS is assigned
the _result_ of _printing_ a \n.
At least that's how my dusty brain seems to remember... ;-)
