Well, spaces and quotes are allowed in Unix (and Linux) filenames, so
I'm not sure what you are doing here.

This is crazy.

replace($filename, "[ '\\`&;]", "\\&")
will probably do what you want.

Or use \s instead of space if there might be newlines.

You might also need to replace " with \"

I'm guessing you are passing the filename to a program, since you for
sure don't want to put backslashes in a path.

Also watch for filenames including things
like ../../../../../../etc/passwd :-)
