[TriLUG] help converting a perl script to zshell

[Aaron S. Joyner]

One question about your perl code -- what does $files; do and why do you 
have $dirty as part of your string?  Neither are doing anything, I would 
guess that they're left-overs from some previous iteration where you 
were testing or doing something else in particular?

If your description is correct, and you just want to a list of files 
with meta characters in the name, that's actually quite easy to do by 
chaining together a few common *NIX utilities - consider this:
file /your/directory | grep '[*?%$@#^!()]'
That will give you a list of every file which contains a character in 
the big gobbeldeygook of special characters.  You may of course add and 
remove them at will, as long as you leave the []'s, and don't put a ^ as 
the first character after the [, or it will match precisely the opposite 
of what you expect.  If you want to accomplish the same task in pure 
zshell (say for inclusion on a tiny distro or something), then more 
thought will be required.  I don't do that much thought unless it's 
really required.  :)  Unless zsh has support for regex's or some pretty 
good pattern matching or substitution, it's going to be difficult, at 
best. 

Okay I don't know much about zsh so I got curious.  A quick skim of "A 
User's Guide to ZSH" turned up that you could probably do what you want 
with a zsh pattern match like this:
[^[:alpha:][:digit:]-/.]
getting the list of files into a zsh variable, and the rest of the 
fluff, is left as an exercise to the reader (think: @dir = `ls`).
