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.
