comparing two directory structures

[Omer Zak]

If you want to compare filenames, size, ownership and last update time:

  cd directory1
  ls -alR > /tmp/dirlist.1
  cd directory2
  ls -alR > /tmp/dirlist.2
  diff /tmp/dirlist.1 /tmp/dirlist.2

If you want to compare only sizes and filenames:

  cd directory1
  ls -alR | cut -d\  -f 5- > /tmp/dirlist.1
  cd directory2
  ls -alR | cut -d\  -f 5- > /tmp/dirlist.2
  diff /tmp/dirlist.1 /tmp/dirlist.2

If you want to compare only filenames:

  cd directory1
  ls -aR > /tmp/dirlist.1
  cd directory2
  ls -aR > /tmp/dirlist.2
  diff /tmp/dirlist.1 /tmp/dirlist.2
