Indeed.

  $ sha256 /usr/bin/less /usr/bin/more
  SHA256 (/usr/bin/less) = 9d517bcdf5bb22e756337ee450657de4d4edba779f7c17acfcaf7ba71f76bf59
  SHA256 (/usr/bin/more) = 9d517bcdf5bb22e756337ee450657de4d4edba779f7c17acfcaf7ba71f76bf59

The `more` command is often provided by `util-linux` package.

Ubuntu 12.04:

    dpkg -S /bin/more /bin/less

    util-linux: /bin/more
    less: /bin/less

CentOS 5.10:

    rpm -qf /bin/more /usr/bin/less

    util-linux-2.13-0.59.el5_8
    less-436-9.el5

Using Ubuntu 12.04

        md5sum /bin/less /bin/more 
        4be69e915a4b4514d3d06ee07dd56a68  /bin/less
        11fc84952b1f31a91b5b6ec29740e497  /bin/more

Or it just my system?
