Hi,
I have this in ~/.kshrc :
PS1="\u@\h:\w\$ "
which works fine in ksh:
oc@OpenBSD:~$
However, if I open a sh subshell, I get:
\u@OpenBSD:\w$
which is not very nice. The only hack I've found is to append this to
~/.profile:
if [ -n "$KSH_VERSION" ]; then
if [ -f "$HOME/.kshrc" ]; then
. "$HOME/.kshrc"
fi
fi
I wonder if there is a more elegant solution.
Hi,
the more elegant solution is to set ENV appropriately. ~/.profile is
normally read only at login, while sub-shells will source whatever
file is specified in ENV.
This is what I had and it generated the undesired prompt in sh.
You probably mean "interactive shells", not just sub shells. A sub shell
could be child of a non login shell as well.
With ENV=~/.khsrc, PS1 is propagated over to sub shells, whether it is
ksh or sh, whereas just sourcing ./.khsrc will not export PS1. I don't
know why this is. It doesn't make sense to me. Maybe it's just because
OpenBSD sh is just ksh in disguise or there might be other reasons that
I obviously don't know.
