Re: limit scope of variable

[Vin Shelton <acs@xxxxxxxxxxxxxxxxxxxx>]

I think you can prefix the called function with IFS=$OLDIFS.  I.e.:

IFS=$OLDIFS Rays_function

E.g.:

function a {
; echo $a
; }
: ~ Tue 3 16:37; a=foo
: ~ Tue 3 16:37; a
foo
: ~ Tue 3 16:37; a=bar a
bar
: ~ Tue 3 16:37; a
foo

I have a function that requires this:

$IFS from that change.  Can I limit the scope?  As it is I'm laboring it
with this:

In the calling function:

      local OLDIFS="$IFS"
      local IFS=$'\n'

In the called function:

     IFS=$OLDIFS

     code ...
     code ...

     IFS=$'\n'
     return

... there's got to be a more streamlined way.
