to exclude several directories that are below the directory I am searching.
When I used -name like in this post
w w w . unix.com / unix-dummies-questions-answers/16921-question-non-recursive-find-syntax.html
(had to put in spaces... forum wouldn't let me post otherwise)
(There are many other directories under /home/username/public_html/ that I want to search - just in case that information makes a difference.)
I'm trying to write my script so I can easily configure multiple exclude directories in (a) shell variable(s), but as long as I know how to write the general form of the statement with 2 or 3 exclusions, I should be able to work the rest out.
Any help would be most appreciated.

Reason: Please use code tags for data and code samples
That means that -name '/home/username/wd/'' will probably evaluate to false all the time on this system. You might find the -wholename test more useful, or perhaps -samefile. Alternatively, if you are using GNU grep, you could use find ... -print0 | grep -FzZ '/home/username/wd/'.
find: warning: Unix filenames usually don't contain slashes (though pathnames do). That means that -name '/home/username/mail' will probably evaluate to false all the time on this system. You might find the -wholename test more useful, or perhaps -samefile. Alternatively, if you are using GNU grep, you could use
and got a ton of error messages md5sum: /../.../../: Is a directory. And all the directories under /home/username/mail were still included. -print isn't needed because I only need the output from the md5sum, and "" must be used for the substituion from find to work. The find must only give files, not directories so I also tried:
which still gave a ton of errors about Is a directory and both the directories that should have been excluded were processed.
Any suggestions?

Well, think this'll work - if you need more complicated directory matching you could just get the entire list of directories and then use grep -v instead of the find -type d:
Code:
#!/bin/sh
STARTDIR="/home/XXX/.cache"
EXCLDIRS="Thunar sessions"
exclude=""
for dir in ${EXCLDIRS}; do
exclude="${exclude} -name ${dir} -o"
done
# Lil sloppy, but just kill the -o at the end.
exclude="`echo $exclude | sed 's/-o$//'`"
# Run the find - this will produce all the directories we -want-
find ${STARTDIR} -type d -a \! \( ${exclude} \) -print | while read line; do
# and this will run whatever we want against the files in them...
find ${line} -type f -exec md5sum {} \;
done
to exclude several directories that are below the directory I am searching.
Code:
find "$path" -type d \( -iwholename "$ScriptDir" -o -iwholename "$anotherDir" \) -prune \
-o -type f -exec md5sum {} +
This approach should also run faster because md5sum is no longer called once per file.

The original solution excludes all files below the excluded directory. Your approach will include files in subdirectories below any excluded directories.
On an unrelated note, we do not know for certain if there are directories with whitespace in their names (increasingly common these days). If there are, your solution won't work.
find "$path" -type d \( -iwholename "$ScriptDir" -o -iwholename "$anotherDir" \) -prune \
-o -type f -exec md5sum {} +
is exactly what I am looking for - works great & really fast as you said.
A couple of follow ups:
What does the + sign do?
Thanks for the comment about the whitespace-I hadn't thought about that. (I don't believe that whitespace is legal on an apache server, but the MD5 does work on files in the tree that contain white space (I tested it)). If I did need to use a directory that incudes whitespace, could I just include escape sequences in the exclude variables?
@nixie
1) Post #1 was the worst formatted post I have seen in months.
2) Please use code tags when posting code or data.
3) Please avoid punctuating code with English punctuation - particularly quotes. It makes the code read like nonsense.
4) Please do not a use Microsoft character set when posting unix code. Copy/paste via Windows Notepad to get rid of weird characters which have no meaning in unix scripts.
5) Please mention what Operating System and version you have and what Shell you are using. There is much variation on the find command and you and @alister refer to much obscure syntax which is definitely not from a unix find.

Please avoid posting untested and erroneous code. Where does $X come from? How does you code work for multiple directories?

Find all files in the current directory only excluding hidden directories and files.
For the below command, though it's not deleting hidden files.. it is traversing through the hidden directories and listing normal which should be avoided.
