28 | For each NAME, specify how arguments are to be completed. |
29 | If the -p option is supplied, or if no options are supplied, existing | |
30 | completion specifications are printed in a way that allows them to be | |
31 | reused as input. The -r option removes a completion specification for | |
32 | each NAME, or, if no NAMEs are supplied, all completion specifications. | |
