hash -r 的帮助文档

       hash [-lr] [-p filename] [-dt] [name]
              Each time hash is invoked, the full pathname of the command name is determined by searching the directories in $PATH and remembered.  Any previously-remembered pathname is
              discarded.  If the -p option is supplied, no path search is performed, and filename is used as the full file name of the command.  The -r option causes the shell to forget
              all remembered locations.  The -d option causes the shell to forget the remembered location of each name.  If the -t option is supplied, the full pathname  to  which  each
              name corresponds is printed.  If multiple name arguments are supplied with -t, the name is printed before the hashed full pathname.  The -l option causes output to be dis‐
              played in a format that may be reused as input.  If no arguments are given, or if only -l is supplied, information about remembered commands is printed.  The return status
              is true unless a name is not found or an invalid option is supplied.
