Best backup option for spanning CDR's?

[Michael Bilow]

Well, there is the obvious way:

$ if [ "`file -b /etc/motd`" == 'text' ] ; then echo YES ; fi
YES

This actually does what you want:

$ for TESTFILE in `find / -size '-300k'` ; do if [ "`file -b "$TESTFILE" |
grep -c -etext -`" -ge 1 ] ; then echo "$TESTFILE" YES ; fi ; done

Obviously, replace 'echo "$TESTFILE" YES' with something more useful.

On an ideally organized distribution, you should be able to depend upon
configuration files being in /etc, other system variable files being in
/var, and user variable files being in /home (or /root).  In general,
/bin, /usr, and /sbin should contain nothing specific to your system,
usually under package management and therefore easily reinstallable.
