linux shell tar unwanted extra directories - linux

I have the following problem:
I have directorties a/b/c and inside c many text files.
I want to make a .tar.gz file in drectory a/mydir with the c directory inside and then unzip it to that same directory to create a/mydir/c (with all the files inside)
I am at directory a and run: (shell)
~:$ tar -czf mydir/output.tar.gz b/c
~:$ tar -zxf mydir/output.tar.gz -c mydir
but the result is directories a/mydir/b/c (with the files inside)
The problem is I don't want directory b in the middle, just c with all its contents

This works for me. Create data
mkdir -p a/b/c
echo 42 > a/b/c/file.dat
Archive
tar zc -f c.tar.gz -C a/b c

created a/b/c directories, from directory a kindly try this command.
so the file under b/c/files were done out.tar.gz
new directory "mydir" create under "b" and files extracted too.
out.tar.gz removed from "a".
# tar -cvzf out.tar.gz b/c/* ; mkdir -p b/mydir ; tar -xvzf out.tar.gz -C b/mydir/ ; rm -rf out.tar.gz
Thanks!

Loop through directory and zip specific folder without parent path

I'm trying to make a bash script to loop through all folder in directories, and individually zip just the folder I want without all path and choose where to zip theme.
#!/bin/bash
for dir in /MyPersonalFolder/*/*/WhatIWantFolder
do
folder_number=$(basename ${dir%/*}) ### basename get the name of this folder [*] 'folder have numbers' /MyPersonalFolder/*/[*]/WhatIWantFolder
sudo tar -cf "${folder_number}-WhatIWantFolder".tar.gz --absolute-names "$dir"
mkdir -p ./backup-theme/ && sudo mv "${folder_number}-theme".tar.gz $_ ### I use this to move zipped folder to specific directory if i can choose where to zip file in the zip command line it's better
done
I can zip the folder I want, but the output zip file comes with this content:
/MyPersonalFolder/0001/0001/WhatIWantFolder
But what I need is to output the file with this path:
0001/
|___WhatIWantFolder/
I tried to change "$dir" in this line
sudo tar -cf "${folder_number}-WhatIWantFolder".tar.gz --absolute-names "$dir"
with basename ${dir%/*}
sudo tar -cf "${folder_number}-WhatIWantFolder".tar.gz --absolute-names "basename ${dir%/*}"
tar not found the folder it's come with errors
tar: e0001: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
You can cd to another directory while running tar using the --cd option.
#!/bin/bash
for dir in MyPersonalFolder/*/*/WhatIWantFolder; do
parent="${dir%/*/*}"
subdir="${dir#*/*/*}"
outfile="backup-theme/${subdir/\//-}.tar.gz"
tar --cd "$parent" -cvzf "$outfile" "$subdir"
done
The directory structure of the tar file would look something like this:
tar -tf backup-theme/0001-WhatIWantFolder.tar.gz
0001/WhatIWantFolder/
0001/WhatIWantFolder/f1

Can tar extraction erase brother directory ?

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

What is the linux command to move the files of subdirecties into one level up respectively

The path structure of the files on my server is similar to shown below,
/home/sun/sdir1/mp4/file.mp4
/home/sun/collection/sdir2/mp4/file.mp4
I would like to move the files of "mp4" into one level up(into sdir1 and sdir2 respectively)
So the output should be,
/home/sun/sdir1/file.mp4
/home/sun/collection/sdir2/file.mp4
I have no idea to do this, so not tried yet anything...
There are different ways to solve your problem
If you just want to move those specific files, run these commands:
cd /home/sun/
mv sdir1/mp4/file.mp4 sdir1/
mv sdir2/mp4/file.mp4 sdir2/
If you want to move all mp4 files on those directories (sdir1 and sdir2), run these commands:
cd /home/sun/
mv sdir1/mp4/*.mp4 sdir1/
mv sdir2/mp4/*.mp4 sdir2/
Edit:
Make a script that iterates all the directories:
Create a script and name it and edit it with your favorite editor (nano, vim, gedit, ...):
gedit folderIterator.sh
The script file content is:
#/bin/bash
# Go to the desired directory
cd /home/sun/
# Do an action over all the subdirectories in the folder
for dir in /home/sun/*/
do
dir=${dir%*/}
mv "$dir"/mp4/*.mp4 "$dir"/
# If you want to remove the subdirectory after moving the files, uncomment the following line
# rm -rf "$dir"
done
Save the file and give it execute permissions:
chmod +x folderIterator.sh
And execute it:
./folderIterator.sh
You can do this:
# move all .mp4 files from sdir1/mp4 to sdir1 directory
user#host:~/home/sun$ mv sdir1/mp4/*.mp4 sdir/
# move all .mp4 files from collection/sdir2/mp4 to collection/sdir2 directory
user#host:~/home/sun$ mv collection/sdir2/mp4/*.mp4 collection/sdir2/
# move only 1 file
user#host:~/home/sun$ mv sdir1/mp4/file.mp4 sdir/
user#host:~/home/sun$ mv collection/sdir2/mp4/file.mp4 collection/sdir2/
I suggest you use find and something like
cd /home/sun/sdir1/mp4/
find . -name "*" -exec mv {} /home/sun/sdir1/ \;
cd /home/sun/collection/sdir2/mp4/
find . -name "*" -exec mv {} /home/sun/collection/sdir2/ \;
Alternatively, you could use tar and something like
cd /home/sun/sdir1/mp4/
tar cfp - * | (cd ../ ; tar xvvf -)
# Make sure everything looks good
rm -rf mp4
cd /home/sun/collection/sdir2/mp4/
tar cfp - * | (cd ../ ; tar xvvf -)
# Make sure everything looks good
rm -rf mp4
The command to move a file (or directory) up one level is:
mv /home/sun/sdir1/mp4/file.mp4 ..
Wildcards can be used to select more files & directories, you can also provide more than one directory at a time.
mv /home/sun/sdir1/mp4/*.mp4 /home/sun/collection/sdir2/mp4/*.mp4 ..

tar Linux command exluding subdirectories´ hierarchies (but including their files)

I have the folder a with two files (1,2), and the subfolder b with another two files (3,4).
I ´d like to tar a with '1,2,3,4' files in the tar file, but not including b.
(By default (tar cvf), b is added, and '3,4' are inside b. How can I do it?)
Thanks
you can use a script like this:
# ! /bin/sh
files=`cat list.list`
tarname="test.tar"
tarpath=`pwd`
#create empty tar
tar -cvf $tarpath/$tarname --files-from /dev/null
for curr_file in $files
do
#add each file separatly
cd `dirname $curr_file`
tar -uvf $tarpath/$tarname `basename $curr_file`
cd -
done
and create the filelist with a command like this:
find -type f > list.list

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
