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.
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.
I have a folder structure from there i am backing up files which are modified
Below is folder structure
/home/aaditya/customer/jiva/foo/bar/File1.txt
Using below command i want to backup File1.txt file
cd /home/aaditya/customer/jiva/foo/bar
tar -zcvf archive_backup_folder.tar.gz File1.txt
But my problem statement is that when i unzip the tar archive_backup_folder, File1.txt should be there inside customer/jiva/foo/bar/File1.txt not only File1.txt
Can anybody help me how to do that.
Just do:
cd /home/aaditya/
tar -zcvf archive_backup_folder.tar.gz customer/jiva/foo/bar/File1.txt
That is, include the path structure in the archive.
You can try something like this
TIME=`date +%b-%d-%y`
FILENAME=backup-$TIME.tar.gz
SRCDIR= directory or file that has to be backed up
DESDIR= place where you need to store it
tar -cpzf $DESDIR/$FILENAME $SRCDIR
cd /home/aaditya/
find customer -mtime -1 -exec tar -rvf test.tar {} \;
the "find" command will find out all files modified within 1 day and for each of them, run "tar -rvf test.tar the_file" to add it to test.tar (you way want to "rm -f test.tar" before running the "find" command
I made several backups on different directories with Backup Manager. Eg: /home/user1 /home/user2...
It gives me some tar files. The content of a tar file looks like :
home/user1/
home/user1/.profile
home/user1/.bash_history
home/user1/.bash_logout
...
I tried to test the restoration with something like :
tar -xvzf home.user1.tar.gz -C home/user1
But the command above recreate all the structure inside the choosen directory. That gives /home/user1/home/user1/filname1.
So I guess I should use the command specifying the home directory (/home) instead of the user directory. But is there any risk to erase other user's directories in /home ?
Thks for your time.
Actually tar does not erase data as a default. But any files that are contained within the tar archive will overwrite files of the same name if they are already present. Likewise a sub-directory's contents will not be overwritten if the tar archive does not contain files matching them.
mkdir -p foo/bar/
touch foo/file1 foo/bar/file1
tar -cf foo.tar foo/
rm -rf foo
mkdir -p foo/bar/
touch foo/file2 foo/bar/file2
tar -xf foo.tar
ls foo foo/bar/
As once can see both file1 and file2 are present and the newly unarchived directory did not overwrite the old. Here is the output of ls from my system:
foo:
bar file1 file2
foo/bar/:
file1 file2
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
