Those attributes are for Windows files, not UNIX files. e.g., there is no such thing as a hidden UNIX file.

Using `ls -lastr` would give you a decent list of file properties. The "hidden" files in linux are typically called "dot files". If you preceed the filename with a dot (as in .fileName), it would "hide" from the default `ls` command.

The -a flag of the ls command would find all dot files, so in effect they aren't really hidden. However, you could probably effectively hide a file by prefixing the filename with nongraphic characters. Although the -b flag of `ls` would print octal escapes in the place of the nongraphic character... The use of -b is not as commonly known as -a.

When in doubt, encrypt the file and change ownership and permissions.

IF -

I disagree - you can hide unix files the way you describe but stat - which is the definitive statement about file properties -- does not have any such thing as hidden in UNIX files. Windows filesystems support that property - as well as archive, etc.

I am not arguing "functionality" I'm arguing defined properties - what you did was to confuse the poor OP. IMO.

I guess shell scripting includes windows/DOS bat files. There isn't a stat shell command available from standard Windows XP distributions, so that leaves UNIX

Well, Linux stat....

Hence, the comment.

By the way, Windows files having the archive flag means nothing. I've seen many non-archive files with it.

The Archive flag was created so backup utilities would know which files to back up. I don't believe it's used much in practice.
