Hi, Dave.

You can try something like find <path_here> -type f -exec bcwipe -Smd {} \;
Remember, it will be lenghty operation if you have many files there.

That 'something like' bothered me so I worked on it, and registered just to add this material, since it is relevant.

This works:   find / -type f -execdir bcwipe -S -mz -v '{}' \;

     Substitute your path for / which takes a very long time
     -execdir has increased security over -exec.  -okdir allows you to approve each file slack wipe with y or Y This works for testing bcwipe
     -S is wipe slack option
     -mz is one-pass zeroes; see list. -me is 3-pass DoE. or whichever method you prefer
     -v is verbose mode
             See 'man find' and 'bcwipe' for the details.  -execdir takes output of find and executes the stated command on that file.

How do you wipe slack space from all files in Linux?  There appears to be two issues here: one is that you can't wipe recursively into directories, and two, you can't wipe hidden files unless you explicitly state the filename or use the .* wildcard.  I am looking for an easy solution to wipe ALL files including those found recursively in subdirectories.

I have tried bcwipe -Smd / , but it comes back with the message "/ is a directory   - Skipping".  
I have also tried bcwipe -Smd * , which appears to wipe slack on all unhidden files in the current directory only.

Thanks,
Dave...
