Directories' contents difference

[Ferdie Castro]

Hi, is there a command to check any discrepancies between two directories. for example for a file its diff file1 file2
How can I be able to see discrepancies between two directories in terms of files, sub-directories within it and number of bytes of that files?
thanks.
example command
then outputs me discrepancies letsay dir1 has file1 with 10 bytes but in dir2 file1 has 12bytes

why not try:
ls -lR dir1 > file1
ls -lR dir2 > file2
diff file1 file2

You can use
dircmp dir1 dir2
or
diff -r dir1 dir2
