Unzip a single file in a tbz archive - linux

I have the following archived directory:
itunes20140618.tbz
I want to extract single file from it called:
itunes20140618/video
How would I do this?
So far, I am doing
$ bzip2 -d /tmp/itunes20140618.tbz
But it seems to create a tar directory of everything. How would I extract just the single video file?


There are a few different versions of tar around, but on my machine I can do this:
tar xjf archive.tbz filename
To extract filename from archive.
If that doesn't work you can use:
bzip2 -dc archive.tbz | tar xvf - filename
Which uses bzip2 to extract to stdout and then pipe to tar.
In both cases you can replace the x option with t to get a list of files. Eg:
tar tjf archive.tbz


You can use the tar command and pass the path of the desired file or folder as an argument to it:
tar xjf test.tbz /path/to/file/in/archive

How to list the folders/files of a file.tar.gz file inside a file.tar

I need to list the folder/files inside a certs.tar.gz which is inside file.tar without extracting them.
[root#git test]# tar -tf file.tar
./
./product/
./product/.git/
./product/.git/refs/
./product/.git/refs/heads/
./Release/add_or_modify.sh
./certs.tar.gz
[root#git test]#

You may want to use and condition:
tar -xf abc.tar "abc.tar.gz" && tar -ztvf abc.tar.gz
Explanation:
For listing of files we use
If file is of type tar.gz:
tar -ztvf file.tar.gz
If file is of type tar:
tar -tvf file.tar
If file is of type tar.bz2:
tar -jtvf file.tar.bz2
You can also search for files in any of the above commands. e.g:
tar -tvf file.tar.bz2 '*.txt'
For extracting files we use
tar -xf file.tar
In these commands,
t: List the contents of an archive.
v: Verbosely list files processed (display detailed information).
z: Filter the archive through gzip so that we can open compressed
(decompress) .gz tar file.
j: Filter archive through bzip2, use to decompress .bz2 files.
f filename: Use archive file called filename.
x: Extract all files from given tar, but when passed with a filename
will extract only matching files

Archive all the files from source directory into a xyz.gz file and move that to target directory using UNIX shell script

Requirement: Archive files using UNIX shell script into .gz format without directory structure
I am using below command
tar -C source_dir -zcvf target_dir/xyz.gz source_dir
example:
tar -C /home/log -zcvf /home/archive/xyz.gz /home/log
here xyz.gz contains /home/log
It's creating xyz.gz file maintaining the directory structure. I want only files to be archive without directory structure.

You can try the following command:
$ cd /home/log
$ tar zcvf /home/archive/xyz.gz *

You can use the --transform option to strip leading path components from the archived file names using a sed espression:
tar -C /home/log -zcvf /home/archive/xyz.gz --transform 's_.*/__' /home/log
This however will also write an entry for each encountered directory. If you don't want that, you can use find to find only regular files and pass them to tar on stdin like this:
cd /home/log
find -type f -print0 | tar -zcvf /home/archive/xyz.gz --transform 's_.*/__' --verbatim-files-from --null -T -
Note that this may create multiple entries with the same name in the tar archive, if files with the same name exist in different subdirectories. Also you should probably use the conventional .tar.gz or .tgz extension for the compressed tar archive.

Untar multiple *.tar.gz.aa *.tar.gz.ab pattern files

I tarred a folder and split it into tar.gz files of 200mb when zipping. How can I go about unzipping them? Is there a way I can do this in one command or do I have to do each one separately?

You even cannot do it separately.
Just undo what you did in reversed order:
first concatenate them
then unzip them
then untar
So you do
cat *.tar.gz.* | zcat | tar xvf -
or, even shorter,
cat *.tar.gz.* | tar xvfz -

You can use the bellow :
$ cat *.tar | tar -xvf - -i
cat command, listed .tar files, then listed files will extracted with tar -xvf - -i command.

Special characters in the extracted text file compressed with tar gzip

When i create the archive of a text file with this command:
tar -zcvf file.gz file.txt
and then i extract it get some strange characters in the begin and in the end of file like these:
\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\00\000000644\
How can i remove them? Is it any case to create archive of the one single text file without these special characters?

tar cfz creates a gzipped tar: file.tar.gz. It is the same as tar cf file.tar followed by gzip file.tar.
Extract such a file with tar xvfz (or gunzip file.tar.gz && tar xvf file.tar, but the z is shorter).
For single files use gzip and gunzip (possibly with -k or --keep to keep the original file).

How do I tar a directory without retaining the directory structure?

I'm working on a backup script and want to tar up a file directory:
tar czf ~/backup.tgz /home/username/drupal/sites/default/files
This tars it up, but when I untar the resulting file, it includes the full file structure: the files are in home/username/drupal/sites/default/files.
Is there a way to exclude the parent directories, so that the resulting tar just knows about the last directory (files)?

Use the --directory option:
tar czf ~/backup.tgz --directory=/home/username/drupal/sites/default files

Hi I've a better solution when enter in the specified directory it's impossible (Makefiles,etc)
tar -cjvf files.tar.bz2 -C directory/contents/to/be/compressed .
Do not forget the dot (.) at the end !!

cd /home/username/drupal/sites/default/files
tar czf ~/backup.tgz *

Create a tar archive
tar czf $sourcedir/$backup_dir.tar --directory=$sourcedir WEB-INF en
Un-tar files on a local machine
tar -xvf $deploydir/med365/$backup_dir.tar -C $deploydir/med365/
Upload to a server
scp -r -i $privatekey $sourcedir/$backup_dir.tar $server:$deploydir/med365/
echo "File uploaded.. deployment folders"
Un-tar on server
ssh -i $privatekey $server tar -xvf $deploydir/med365/$backup_dir.tar -C $deploydir/med365/

To gunzip all txt (*.txt) files from /home/myuser/workspace/zip_from/
to /home/myuser/workspace/zip_to/ without directory structure of source files use following command:
tar -P -cvzf /home/myuser/workspace/zip_to/mydoc.tar.gz --directory="/home/myuser/workspace/zip_from/" *.txt

If you want to tar files while keeping the structure but ignore it partially or completely when extracting, use the --strip-components argument when extracting.
In this case, where the full path is /home/username/drupal/sites/default/files, the following command would extract the tar.gz content without the full parent directory structure, keeping only the last directory of the path (e.g. files/file1).
tar -xzv --strip-components=5 -f backup.tgz
I've found this tip on https://www.baeldung.com/linux/tar-archive-without-directory-structure#5-using-the---strip-components-option.

To build on nbt's and MaikoID's solutions:
tar -czf destination.tar.gz -C source/directory $(ls source/directory)
This solution:
Includes all files and folders in the directory
Does not include any of the directory structure (or .) in the final product
Does not require you to change directories.
However, it requires the directory to be given twice, so it may be most useful in another script. It may also be less efficient if there are a lot of files/folders in source/directory. Adjust the subcommand as necessary.
So for instance for the following structure:
|- source
| |- one
| `- two
`- working
the following command:
working$ tar -czf destination.tar.gz -C ../source $(ls ../source)
will produce destination.tar.gz where both one and two (and sub-files/-folders) are the first items.

This worked for me:
gzip -dc "<your_file>.tgz" | tar x -C <location>

For me -C or --directory did not work, I use this
cd source/directory/or/file
tar -cvzf destination/packaged-app.tgz *.jar
# this will put your current directory to what it previously was
cd -

Kindly use the below command to generate tar file without directory structure
tar -C <directoryPath> -cvzf <Path of the tar.gz file> filename1 filename2... filename N
eg:
tar -C /home/project/files -cvzf /home/project/files/test.tar.gz text1.txt text2.txt

tar -Cczf ~/backup.tgz /home/username/drupal/sites/default/files
-C does the cd for you
