Thanks for the quick reply guruprasadpr

I tried

Code:

ScriptDir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"  # Evaluates to /home/username/wd
X="-name $ScriptDir/ -o -name /home/username/mail"
find $PathToCheck -type d  \( $X \) -prune -o  -print  -exec md5sum '{}' >TestFind.txt

and got the following:

Code:

find: warning: Unix filenames usually don't contain slashes (though pathnames do).

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/'.

Also tried this

Code:

ScriptDir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"  # Evaluates to /home/username/wd
X="-name $ScriptDir/ -o -name /home/username/mail"
find $PathToCheck -type d  \( $X \) -prune -o  -print  -exec md5sum "{}" \;>TestFind.txt

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:

Code:

ScriptDir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"  # Evaluates to /home/username/wd
X="-name $ScriptDir/ -o -name /home/username/mail"
find $PathToCheck -type f  \( $X \) -prune -o  -exec md5sum "{}" \;>TestFind.txt

which still gave a ton of errors about Is a directory and both the directories that should have been excluded were processed.

Any suggestions?
