Subject: limit scope of variable
Date: Tue, 3 Aug 2021 13:15:03 -0700	[thread overview]
Message-ID: <bd1be7c6-1bcd-c762-9add-031abc1744c5@eastlink.ca> (raw)

I have a function that requires this:

     local IFS=$'\n'

... but the function calls other functions in which I need to protect 
$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.
