Hi,

PS1 *must not* be exported.

historically, it is not exported to know if it is a shell is interactive=20
or not since only interactive shells set it.

i.e., the following both solutions are equivalent.

case $- in *i*) interactive ;; esac
[ -n $PS1 ] && interactive

if PS1 is exported, it is always set for subshells and this may cause=20
trouble in some script.

also, from man bash :

An  interactive  shell  is one started without non-option arguments and
without the -c option whose standard input and error are both connected
to  terminals  (as determined by isatty(3)), or one started with the -i
option.  PS1 is set and $- includes i if bash is interactive,  allowing
a shell script or a startup file to test this state.

Regards,

Cyrille Lefevre
