Specifying two file extensions in bash complete

问题

I am trying to modify bash complete properties.

I can exclude a file extension for a command thusly:

complete -f -X '*hi' vim

I want to specify two file names for exclusion. How do I do this?

Note: the following command did not work.

complete -f -X '(*hi|*o)' vim

One way to do this is to turn on Extended Globs. Run this at the command line, or add it to your .bashrc to make it permanent:

shopt -s extglob

Now, your complete command can look like this:

complete -f -X '*.@(hi|o)' vim

Quoting from Extended Globs in patterns:

@(list): Matches one of the given patterns.
