unalias

unalias [-a] name ...

unalias is a shell builtin that removes previously defined command aliases. It can remove specific aliases by name or all aliases at once with the -a flag.The removal only affects the current shell session. Aliases defined in shell startup files like ~/.bashrc or ~/.zshrc will be restored when a new shell is started. This makes unalias useful for temporarily bypassing an alias to test the underlying command's behavior or for debugging shell configuration issues.Returns 0 on success, or a value greater than 0 if a specified alias name does not exist.
