# The hash builtin is most used for the command hash table, which is
|
|
# populated automatically. This is therefore highly system specific,
|
|
# so mostly we'll test with the directory hash table: the logic is
|
|
# virtually identical but with the different table, and furthermore
|
|
# the shell doesn't care whether the directory exists unless you refer
|
|
# to it in a context that needs one.
