The -a option causes unhash to remove regular or global aliases; note when removing a global aliases that the argument must be quoted to prevent it from being expanded before being passed to the command. The -s option causes unhash to remove suffix aliases. The -f option causes unhash to remove shell functions. The -d options causes unhash to remove named directories. If the -m flag is given the arguments are taken as patterns (should be quoted) and all elements of the corresponding hash table with matching names will be removed. unalias [ -ams ] name ...

The options -m (remove by pattern) and -s without -a (remove listed suffix aliases) behave as for unhash -a. Note that the meaning of -a is different between unalias and unhash. unfunction Same as unhash -f.
