Hi,

would it be possible to change :

profile_d ()
{
   saved_LC_COLLATE=${LC_COLLATE}
   LC_COLLATE=C
   for file in /etc/profile.d/*.$1; do
     [ -e "${file}" ] && . "${file}"
   done
   LC_COLLATE=${saved_LC_COLLATE}
   unset saved_LC_COLLATE
}

to :

profile_d ()
{
   for file in $(export LC_COLLATE=C; echo /etc/profile.d/*.$1); do
     [ -e "${file}" ] && . "${file}"
   done
}

PS : LC_COLLATE has to be exported to be effective.

Regards,

Cyrille Lefevre

Hi,

PS1 *must not* be exported.

historically, it is not exported to know if it is a shell is interactive 
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 
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.

What the man page doesn't tell you is that bash actually unsets PS1 if the
shell isn't interactive, so for bash at least, exporting PS1 can't cause a
problem.

thanks for the tip, however, this is not an expected behaviour...

bash isn't the only shell under the Sun.

Funny, an Oracle told me the same thing.

Hello,

Both improvements have been checked in for a future 4.0-7 version.
I'm waiting for dash to be updated to include also a simpler PRINTER
setting as you proposed.
