Re: One more comment on bash with spaces

Greetings :-) Yet one more comment :-(

I think it's then time to move up to a high-level language
like Perl, Python or Lua, where filenames don't get mixed up
with the commands that are working on them.

I think Lua is very good for visually-impaired users, because it
doesn't have much punctuation, and reads like a natural language.

When I used to work as a SysAdmin, I used to dream of building a
Nightmare Directory, with filenames full of quotes, double-quotes,
dollars to mimic variables, backticks to execute commands,
null-characters to trap C-programmers, semicolons, newlines,
brackets and braces matched and unmatched, backslashes,
spaces, tabs, vt100 escape-sequences for some light relief,
and then all of those escaped with backslashes,
and then all of the above escaped with more backslashes and so on ...
But when I actually found myself involved in deploying a new backup
system I found I was too scared to create my Nightmare Directory,
I felt it would succeed :-(

About backups, sysadmin lore is that you must
Always Do A Trial Restore; your backup system is not in place
until you've exercised your restore procedures. And preferably :
 1) We lost some files
 2) We lost the operating system as well
 3) We lost the machine, the discs and everything
but it's time-consuming, and often gets skipped in practice ...
