Bash completion for path in argument (with equals sign present)

Question

I used to be able to type the following:

$> ./foo --arg=

Where foo is any program I wrote, and it would give me a list of files in the current dir

Answer 1

Not sure what environment you're in, but on a recent CentOS

complete -D -o default

enables filename completion after a token w/o whitespace as the default. To toggle it in the other direction:

complete -D -o nospace

However, it looks like older versions of the builtin don't have the -D option.
