OLDPWD (path)Return the home directory for the current session user
OLDPWD return the previous directory.
This variable exists to support POSIX, however the idiomatic way to access this same data is via $PWDHIST.
This is a reserved variable so it cannot be changed.
PWDHIST is an array that holds the entire PWD history rather than just the previously accessed path.
OLDPWD reads PWDHIST, so if PWDHIST is overwritten, this will affect the value of OLDPWD as well.
If a previous directory cannot be determined, then OLDPWD will error. For example:
» cd $OLDPWD
Error in `cd` (0,1): cannot assign value to $OLDPWD: already at oldest entry in $PWDHIST
> Expression: cd $OLDPWD
