Subject: Question about backquotes and linux echo

Hi all,

I can't figure out why the following works from the command line but not
from the backquotes:

echo -e "a\nb\naa" | grep a

This should produce:

a
aa


However, when I execute:

puts `echo -e "a\\nb\\naa" | grep a`

I get:

-e "a\nb\naa"

Of course, this is a trivial example, but it represents my real problem
well enough.  Writing the text to a temp file and using 'cat' isn't an
option, unfortunately.

Thanks for any help,

Brian Hartin
