I know what you mean, but for one reason or another, there are still a fair number of people stuck on RHEL/CentOS 5.x, and hence using 3.2. Hopefully there will be far fewer such people within the next few years... >> In future versions of Bash, it would be nice if the default Readline >> completion >> could be invoked explicitly, rather than requiring this 'compopt' workaround. > > What syntax would you suggest for doing that?

If COMPREPLY could be something other than an array, that might be used to indicate that some other behavior is desired. For example, perhaps COMPREPLY='complete-filename' could produce the behavior you currently get with '-o default' and COMPREPLY=(), but without needing to set '-o default', of course. I'm not sure how cleanly this would fit into the current scheme of things, but it's just an idea. Jeremy
