[SLUG] Newlines in environment variables

[Peter Hardy]

Pretty basic shell question, but it's Monday morning and my brain hasn't
warmed up yet.

I have the following bit of shell script to accept messages piped from
evolution filters and pop up a notice on screen:


message=Message received

`egrep (^From:|^Subject:)`



xmessage -nearmouse $message

(I'd much rather use zenity or some other xmessage replacement, but
nothing else is available in this environment)

Now, running this script with bash compresses $message to a single line,
while zsh keeps the newlines intact. So I'm wondering how to achieve the
same thing with bash.

Cheers,

xmessage -nearmouse $message

If you don't quote the variable, it is separated by IFS again.
Therefore, there is another answer:

  IFS=
  xmessage -nearmouse $message

Quote $message, as in

$ xmessage -nearmouse $message
