rusty, here are some examples of find.  sometimes the syntax can be a little
confusing, but the more you use it the more you get comfortable with it.
find is very powerful.


list all files on the system:

        find /

list all files starting from /usr/local/tex on downwards:

        find /usr/local/tex/

find any file containing the string "hello", starting from /usr/local going
on downwards.  it -print's the result.  you don't have to use -print since
that's the default behavior, so these two are equivalent:

        find /usr/local/ -name "*hello*" -print
        find /usr/local/ -name "*hello*"


-exec allows you to perform a command on matched files.  this chmod's ALL
files starting from /home going on downwards.  the \{} expands to the name
of the matched file.  i'm not sure what \; is.

        find /home/ -exec chmod go-rwx \{} \;

here's how to delete all empty files starting with /var on downwards:

        find /var/ -empty -rm \{} \;

find all suid programs in /opt:

        find /opt -perm +4000

i'm not entirely sure, but i think this ought to delete all files on your
system.  of course, i'm not willing to try it out.  see if you can figure
out why i say it should delete ALL files on the system.

        find . -name ".*" -exec rm \{} \;

chmod all files, starting with the current directory, but ASK if it's ok
before performing the chmod.  kind of like mv -i or cp -i

        find . -ok chmod ugo-rwx \{} \;

see man find for more details.

there's also something called xargs, which i never learned how to use.
maybe someone on the list will explain how to use it.

precise-amundo.   you can use globbing, just quote the name, ie:

        find / -name "*config"

different tools for the job.  you want to:

1. find a file which may be in your $PATH:    which
2. find a file anywhere on the system:        locate
3. find a file anywhere based on a complicated choosing procedure and
        do something with that file                find || (locate && xargs)
