copymon provides file copying processes with a progress bar. Neither cp nor rsync provide means to monitor the copying process, nor a progress bar. copymon is a wrapper which performs a scan of the directory to be copied and collects information about the files to be copied. After that, it spawns the actual copying program (which can be cp, rsync, or tar) and monitors its progress. copymon can be easily enhanced to support more programs and can be extended to provided different types of progress bars.
debcheckroot is a tool that retrieves file checksums online or from read only media. It provides trusted verification of your root file system at least as far as you can trust your Internet connection or your verification medium (DVD, BD, etc.). Unlike debsums, it doesn't rely on locally stored md5sums which can be modified by an attacker along with the files themselves. It also provides cleaner and better structured output, and can spot files added to your system by someone else.
