Hi,
I came across this thread http://tinycorelinux.com/forum/index.php?topic=8437.0
on the Tiny Core Linux Forums. One of the users came across some information
that lead him to suggest the use of cat to overlay additional .gz files on top
of the tinycore.gz file. This contains the bulk of the filestructure that is
eventually booted.
Now my understanding of cat goes back to a noddy Unix course about 15-20 years
ago, but I always thought the 'cat' stood for 'catalogue' and was used to list
the content of a text file. Having looked at
http://unixhelp.ed.ac.uk/CGI/man-cgi?cat though, I now know that it stands for
concatenate and my previous use of it simply took the file being opened in
standard input and copied it to standard output.
So now I've got that out of the way, can someone explain what cat actually does
with a compressed archive? I assume it doesn't understand the the content, so
is it simply stitching the two together in dumb fashion? If so, how would it be
used to 'overlay' the tinycore.gz contents as is being suggested?
