Sorry - as caja is not working, when it was not working before it
revived, df -h did not work, and so I had assumed that ls would also
not work.

"
bret at bret-Inspiron-580-UbuntuMATE:~$ ls -l /var/log/dmesg*
-rw-r----- 1 root adm 31 Oct 22  2015 /var/log/dmesg
bret at bret-Inspiron-580-UbuntuMATE:~$
"

So, only the one file appears to exist, and, that appears to not
return any lines sought by the zgrep  or grep command.
