Alpha Sort order for Linux Filenames and Directories
Hello, total newbie with a question that I can't figure out.
In Windows and DOS, for years I have used the characters such as underscore, tilde, caret etc. at the beginning of directory names to cause them to go to the top of a file listing. So, in a listing, _Alpha comes before Alpha which comes before Beta.
This same practice works in web apps like Gmail.
In Linux, both File Manager and apps like Thunderbird effectively ignore the pre-characters, so that _Beta comes after Alpha.
Without getting into scripts and macros, what is the sort order in Linux and/or what do the naming conventions allow me to do so that I can create a prioritized directory or file name? Or to restate the obvious, which non-alphanumeric characters sort before the alpha characters?
Thanks for any help.
