compopt 命令

常用示例

说明

compopt is a Bash builtin command used within programmable completion functions to modify completion behavior dynamically. It allows completion functions to change options based on context or arguments. When called without arguments inside a completion function, compopt modifies the options for the current completion. When command names are provided, it modifies the completion specification for those commands, similar to complete -o. This command is essential for creating sophisticated completion functions that adapt their behavior based on what's being completed. For example, a function might enable filename completion only when the user is completing a file path argument.
