Unix tar does not have a built-in (de)compression.
The advantage is that the newest (de)compression methods can be used without updating the tar binary.
The disadvantage is that you must get used to complex shell code.
Example:
The && is safer than the semicolon.
Is it possible to redirect the output from 'tar xvf' to another directory?
The taped tar image is extracting to my / dircetory - even though i'm running the command from /backups.
The contents list of the tape shows files created from /livebackups/...
Thanks

I received a tar file of a directory with 50,000 files in it. Is it possible to extract the files in the tar file without first creating the directory?
ie. Doing tar -xvf filename.tar extracts as follows:
x directory/file1.txt
x directory/file2.txt

Hi,

Hi,
I have tar filw which has multiple directories which contain files.
When i extract using tar -xf the directory structure also get extracted.
I require only files and not directory structures as there will be overhead of moving the files again.
So i searched here and got a solution but... (4 Replies)
I would like to confirm my file.tar is been tar-ed correctly before I remove them. But I have very limited disc space to untar it.
Can I just do the listing instead of actual extract it? Can I say confirm folder integrity if the listing is sucessful without problem?

I'm trying to write a Unix script that will go to a specific directory (/tmp/Sanbox/logs) and tar.gz all the log files in that directory and delete the original files that are older than 2 days. So far I have this but it doesn't work. Any help would be appreciated.

pristine-bz2
PRISTINE-BZ2(1) pristine-bz2 PRISTINE-BZ2(1)NAME
pristine-bz2 - regenerate pristine bz2 files
SYNOPSIS
pristine-bz2 [-vdk] gendelta file.bz2 delta
pristine-bz2 [-vdk] genbz2 delta file
DESCRIPTION
This is a complement to the pristine-tar(1) command. Normally you don't need to run it by hand, since pristine-tar calls it as necessary to
handle .tar.bz2 files.
pristine-bz2 gendelta takes the specified bz2 file, and generates a small binary delta file that can later be used by pristine-bz2 genbz2
to recreate the original file.
pristine-bz2 genbz2 takes the specified delta file, and compresses the specified input file (which must be identical to the contents of the
original bz2 file). The resulting file will be identical to the original gz file used to create the delta.
The approach used to regenerate the original bz2 file is to figure out how it was produced -- what compression level was used, whether it
was built with bzip2(1) or with pbzip2(1).
Note that other tools exist, like bzip2smp or dbzip2, but they are said to be bit-identical with bzip2. Anyway, bzip2 looks like the most
widespread implementation, so it's hard to find bzip2 files that make pristine-bz2 fail. Please report!
The deprecated bzip1 compression method hasn't been implemented.
If the delta filename is "-", pristine-bz2 reads or writes it to stdio.
OPTIONS -v Verbose mode, show each command that is run.
-d Debug mode.
-k Don't clean up the temporary directory on exit.
-t Try harder to determine how to generate deltas of difficult bz2 files.
ENVIRONMENT
TMPDIR
Specifies a location to place temporary files, other than the default.
