Umm, it's a newline, and it should be used as \n (not /n). It's a C style
escape for the new-line character. I beleive using \r will insert a
carrige-return. Anyway, same sort of difference (depending on the
editor).. puts the following text on the next line...
NOTE: *nix text files just use a Newline at the end of each line. DOS
(windows) files use a \r\n pair at the end of each line (Carrige-return,
line feed). To make sense of this, think of a type writer or an old
dot-matrix printer.. carrige return: you've moved the print head back to
the left.. newline/linefeed, rolled through one line.

Lets show an example:
echo "This is a string";
would print out:
This is a string
however:
echo "This is a "string"";
would spit out a pasing error. The quoted string (") ends at:
This is a
however, 'string' and the following "'s would not encasing anything.
Rule of thumb: If you are using double quotes to enclose a string, but you
want double quotes within as well, use \" (called escaping). Same goes for
the $ symbol. within quotes, if you want the symbol to show up, use \$.
Otherwise, it'd try to evaluate it as variable!
This is all documented err, somewhere *digs though manuals*, but strangely
enough I can't find it :-|
hope this helps.
