Trying to set PS1 to reflect the current value of a user environment
variable, when running in sh.
Most of my systems I am running in ksh, and my PS is set as follows:
export PS1=`hostname`'.''$ORACLE_SID> '
so that my prompt always shows the current value of $ORACLE_SID. But
it appears that this syntax doesn't yeild the same results with sh.
There, instead of returning the value of $ORACLE_SID, it simply returns
the literal "$ORACLE_SID".
$ORACLE_SID isn't going to change on you in the middle of a session
unless you eval something that explicitly changes it.
The simple solution is to simply run ksh (my preference) but that
presents certain, uh, political challenges. Is there a simple way of
achieving this same functionality under sh (Solaris 5.9)?
Under what circumstances does this change?
