hey, does anyone know how to omit a few directories when making a tarball recursively.

Lets say


Yet there are certain directories inside foo_dir I want the tarball to omit. How would I go about doing something like that.

Thanks for your time,
Dave

tar itself can't do it, but I would do it using find. Find can handle regexps.

see man find especially the OPERATORS section.

one example from the manual:
find / \! -name "*.c" -print
Print out a list of all the files whose names do not end in .c.

in complete the command would be something like
tar -cvzf myfile.tar.gz `find . -name "bla" | xargs`

for a backup it might be interesting to use the -j flag instead of the -z flag, since bzip2 compression is much better than gzip compression.

Thanks you so much, this is exactly what I needed.

hey one more thing greffov. How can I put a regular expression inside the -name paramater. Or is that impossible. If not I can always pipe it into grep but I would like to do something like this but its not working.

find . -name "*\.(html|php)" -print

greffov

find . -(i)regex ".+\.(html|php.{0,1})" | xargs

I haven't tried the pattern, you might have to use -E to enable extended regular expression syntax.


b.t.w.: for those that feel very lost when reading this, don't worry -- it's just something you'll never be able to do with any GUI.

Good because i have no idea what any of that means! Usually when i see that many symbols together they mean someone is cussing!

Thanks for all the help... I had a few problems at first, but I found that I needed to escape all metacharacters except these [].*

this worked fine -> -iregex '.*\.\(html\|php\)'

greffov

great

can you post up the final complete command to make the tar here, just for reference? (and to make others possibly even more lost ;-) )

b.t.w.: why do you write ".*\.(html|php)" ? Do you have files named .html or .php that you want to be included?

About my files being .html or .php. I see where you're going. But since I can't figure out a way to enable "extended regular expression" I was unable to do a +*
I could always substitute a ..* for a +* but that still wouldn't achieve what you want because the results from the find return the relative or absolute paths. So I tried doing something like this [^/] .* but for some reason that doesn't match anything.

Oh well, in the meantime this works nearly perfect.


Reason i'm doing this is because the only linux box I have access to is my web host, and I'm going use this as a cron job to backup some stuff.

hey what does that thing below user's avatars do. "Add to reputation" I put something for greffov thinking it would go in his profile or something...but nothing. Where does it go.
