This seems like a ideal use for xargs. Try:

	find . -path '*/messages/*' -type f -print0 | xargs -0 chmod 777

The -path is like -name but searches the entire relative filename (i.e.,
including the names of containing directories); the -print0 causes the outp=
ut
filnames to be null-separated, so that filenames that contain returns or
linefeeds will not break the script. The -0 tells xargs to expect a
null-separated list. See the relevant man pages for full details: find(1) a=
nd
xargs(1).
