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

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

---

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
