According to Chris Taylor on 11/28/2005 3:13 AM:
I should point out that hostname is called in /etc/profile for bash as
well ( HOSTNAME=`hostname` <-- should this be being changed to
HOSTNAME=$(hostname) at some point soon?)
There is no difference in this case (both command substitution spellings
are required by POSIX), and `hostname` is more portable to older shells
than $(hostname). However, since all bourne-compatible shells distributed
with cygwin support the newer syntax, and the newer syntax is more
readable, as well as easier to nest, it wouldn't hurt if base-files were
updated to use $() instead of ``.
The reason I mentioned it is that I'm told that the `` syntax is
deprecated (and has been for some time), at least in scripts, ergo it
makes sense to be moving to the newer one.. You're right though, it is a
lot easier to read and nest, and vastly easier to read it when nested..

Spinning complacently in the darkness, covered and blinded by a blanket
of little lives, false security has lulled the madness of this world
into a slumber. Wake up! An eye is upon you, staring straight down and
keenly through, seeing all that you are and everything that you will
never be. Yes, an eye is upon you, an eye ready to blink. So face
forward, with arms wide open and mind reeling. Your future has
arrived... Are you ready to go?
