The command above will execute one chmod command for every file it finds. In theory less efficient because of the overhead of starting a new process for each file.

Quote:

Code:
chmod 070 `find /some_dir -type f`

The second command invokes one chmod process to set the permissions on all of the files that are discovered by find. The biggest potential problem with this command is that the number of files found could cause the command argument limit to be exceeded. If you are wanting to minimise the number of chmod processes that are started, this would be the best method:

Code:
find /path -type f | xargs chmod 0755

The xargs command will invoke chmod with the output from find, ensuring that the maximum argument limit isn't exceeded. If it has to, it will invoke chmod more than once, but you won't have a 1:1 ratio of chmod processes to files found.
