> Ah, LOL I think I need some sleep. This is not a bug. Sorry for all the noise. For those trying to follow along, what's happening is the first time "ref=var" is executed, ref becomes a reference to the variable var. The second time "ref=var" is executed, ref is already a reference to a variable, so the value "var" is assigned to the variable "var". imadev:~$ declare -n ref=var1 imadev:~$ var1=old imadev:~$ declare -p ref var1 declare -n ref="var1" declare -- var1="old" imadev:~$ ref=new imadev:~$ declare -p ref var1 declare -n ref="var1" declare -- var1="new"
