How to manage .tgz files?

cucolin@ · 10-19-2007, 03:27 PM

Is it possible to view just the directories that I backed up? not the whole path? for example:

DataHD/projects/adc/adc002_Hard_Launch/dt/html module prototypes/OfficeLocator/trunk/images/_svn/prop-base/

i just want to see the main directories inside the projects directory such as /adc NOT the whole path. I have around 20 of these. Also is there a way to extract just a particular folder/file from that .tgz file? thanks

Try:
tar -tvzf | cut -f 2 -d /

I don't get to see anything, I only get the DataHD/ directory.

Yes, use the --extract option. See:

man tar

Sorry it is:

cut -f 3 -d \/

in your case.
This will you the third field

Or even better:

cut -f 3 -d \/ | sort -u

thanks guys! I wanted to ask you if there is a file size limitation for tar, I'm tarring a 250GB folder to an external HD, but the tar does not complete maybe only a 1/4 of the total size. thanks again!

Tar does not seem to have a file SIZE limit but it does have a file AMOUNT limit. That is, if the list is too long tar will quit.
I don't know what the max file list is.

gerben12, I'm using your command and it works, but I have around 30 folders which are the ones I want to view, for example:

DataHD/folder1/
DataHD/folder2/
DataHD/folder3/

with your command I'm able to see the folders I want to see, but in this fashion:

folder1/
folder1/
folder1/ (and it repeats for around 2 minutes then it goes to folder2/ and so on)

is there a way to view them in order? folder1 then folder2 then folder3.......folder30.

when I try: cut -f 3 -d \/ | sort -u
I get nothing. It stays frozen until I press Crtl+C

Thanks

Hi,

Like I said:

Put:

tar -tvzf | cut -f 3 -d \/ | sort -u

behind it

Then you will see every dir only once.

cucolin@ · 10-25-2007, 02:37 PM

thanks gerben12, but I already did that as I explained above. Apologies if I didn't explain myself well. thanks!

My fault too. I didnt read well.

Well it will remain frozen untill it gets to the next dir inyour tar file, bcause it isstill in the same directory and busy viewing the tar file.

I guess it will show the next dir after the 2 minutes you waited before.

Try and redirect the output to a file

.... | sort -u > /tmp/file.txt
cat /tmp/file.txt

My guess is you will see your dirs.

Besides that, I dont know if you also have any files in you "upper" dirs, but they will show too.
Havent figured out yethow to avoid those...
