Modify or display completion options.
Modify the completion options for each NAME, or, if no NAMEs are supplied,
the completion currently being executed. If no OPTIONs are given, print
the completion options for each NAME or the current completion specification.
Options:
[tab]-o option
[tab]Set completion option OPTION for each NAME
[tab]-D
[tab][tab]Change options for the "default" command completion
[tab]-E
[tab][tab]Change options for the "empty" command completion
[tab]-I
[tab][tab]Change options for completion on the initial word
Using `+o' instead of `-o' turns off the specified option.
Arguments:
Each NAME refers to a command for which a completion specification must
have previously been defined using the `complete' builtin. If no NAMEs
are supplied, compopt must be called by a function currently generating
completions, and the options for that currently-executing completion
generator are modified.
Exit Status:
Returns success unless an invalid option is supplied or NAME does not
have a completion specification defined.
