#13149 — Compare 2 dir-TREES?

I can't find how to do this common task!
`du | wc -l` will show the NUMBER of files - I think?

-> rsync --list-only /mnt/p15/usr/X11R6/DumyDirTstRsync 
           /usr/X11R6/DumyDirTstRsync
== drwxr-xr-x        4096 2014/12/31 18:46:24 DumyDirTstRsync 
== ! does NOT tell WHAT differences !!

So: `rsync --list-only <Tree1> <Tree2>`  <-- FAILS !!

What am I doing wrong, for this simple/common task?

No.  

find -type f|wc -l

will show the number of regular files

diff -r --brief /mnt/p15/usr/X11R6/DumyDirTstRsync /usr/X11R6/DumyDirTstRsync

('man diff' will list all of the options)

There are several ways. I use this quick n dirty but effective method:

to compare directory trees A and B -

cd /A
find . -type f | sort > /tmp/Afiles
cd /B
find . -type f | sort > /tmp/Bfiles


then to find the extra A files

diff /tmp/Afiles /tmp/Bfiles | grep '< ' > /tmp/Aextras

and to find the extra B files


diff /tmp/Afiles /tmp/Bfiles | grep '> ' > /tmp/Bextras

If your "Afiles" and "Bfiles" inputs are in sorted order, then the
"comm" utility can replace both of the diff calls above.  You'll get an
output showing what only exists in A, what exists in both, and what
only exists in B.

  man comm

for the man page or 

  info coreutils 'comm invocation'

if you want to read the "info" documentation.
