Still learning...

[alexpgp]

One thing I learned yesterday was that tar files are not for editing. :)

I thought I had stumbled upon a slick way of concatenating a group of text files (which is what HTML files are, essentially) into one large file (which is what tar does, essentially), but was disabused of that notion when I tried to "untar" the result, which threw a bunch of errors at me. The content had somehow, "inexplicably" changed (because I had changed it using a text editor), and that was enough to throw everything off.

All was not lost, however, as I was able to open the edited tar file and manually extract all forty-odd files, one by one, and save them as required. Something of a lesson for me, I guess.

My eyeballs are ready to stage a coup d'etat, so I think I'll quit the house for a few hours and go look at trees, or something.

Cheers...

tar -cvf archiveName.tar directory

tar -xvf archiveName.tar

and to make a tar into a compressed tar
gzip archiveName.tar
turns into archiveName.tar.gz

and to decompress
gunzip archiveName.tar.gz
turns into archiveName.tar

Thank you for the information.

Use cat. Given three text files whose content is the same as the file name ...

% ls
one.txt three.txt two.txt
% cat one.txt two.txt three.txt > four.txt
% more four.txt
one
two
three
%

Ah, but what I need is something that'll take one.txt, two.txt, and three.txt and create a file that looks like this:

--one.txt--
one
--two.txt--
two
--three.txt--
three

so I can go in, edit the content (making sure not to mess with file delimiters), and eventually use another one-liner to split this combined file into its constituents.

With a little time, I'm sure I could've put together a suitable Perl script to do the job, but a wholly inadequate knowledge of how tar works led me astray.

Thanks for the suggestion.

Cheers...
