User: Cowboy
Functions: cd tar

Simple tar pipe to be used to copy directories while including hidden files and maintaining file permissions

find ./ -iname "*.dmp" -maxdepth 0 -type f -exec tar czvf {}.tar.gz --remove-files {} \; \;
2011-09-07 08:36:29
User: evilinside
Functions: find tar

This command will :

-Archive all *.dmp files individually (one file per archive) from current directory .

-Delete original file after has been compressed.

svn st -q | cut -c 2- | tr -d ' ' | xargs tar -czvf ../backup.tgz
2011-08-31 10:30:29
User: titus
Functions: cut tar tr xargs

This works more reliable for me ("cut -c 8-" had one more space, so it did not work)

find . -type d|xargs tar rf ~/dirstructure.tar --no-recursion
2011-08-03 16:21:10
User: gdevarajan
Functions: find tar xargs

The original suggestion did not work for me, when operating on folders located on an external mount (ie other than the root device) in Ubuntu. A variation using xargs does the trick.

ssh -C USER@HOST tar -c --exclude /proc --exclude /sys / | tar -x
cd / ; tar -cvpzf backup.tar.gz --exclude=/backup.tar.gz --exclude=/proc --exclude=/lost+found --exclude=/sys --exclude=/mnt --exclude=/media --exclude=/dev /

User: strzel_a
Functions: cd tar

Backup your entire system on a tar ball file format.

tar cf - . |(cd /targetdir; tar xvf -)
for i in *.tar.gz; do tar -x -v -z -f $i && rm -v $i; done
for i in "*.txt"; do tar -c -v -z -f $i.tar.gz "$i" && rm -v "$i"; done
tar -caf some_dir.tar.xz some_dir
2011-06-09 19:00:06
Functions: tar

the -a flag causes tar to automatically pick the right compressor to filter the archive through, based on the file extension. e.g.

"tar -xaf archive.tar.xz" is equivalent to "tar -xJf archive.tar.xz"

"tar -xaf archive.tar.gz" is equivalent to "tar -xzf archive.tar.gz"

No need to remember -z is gzip, -j is bzip2, -Z is .Z, -J is xz, and so on :)

tar jcpf /home/[usuario]/etc-$(hostname)-backup-$(date +%Y%m%d-%H%M%S).tar.bz2 /etc
2011-04-29 22:53:11
User: mack
Functions: date tar

Simple Compressed Backup of the /etc

Linux compatible

mkdir copy{1,2}; gzip -dc file.tar.gz | tee >( tar x -C copy1/ ) | tar x -C copy2/
2011-04-14 17:02:05
User: depesz
Functions: gzip mkdir tar tee
Tags: bash tee tar

Sometimes you might need to have two copies of data that is in tar. You might unpack, and then copy, but if IO is slow, you might lower it by automatically writing it twice (or more times)

svn diff -r 1792:HEAD --summarize | awk '{if ($1 != "D") print $2}'| xargs -I {} tar rf incremental_release.tar {}
2011-04-05 15:00:49
User: windfold
Functions: awk diff tar xargs
Tags: bash svn awk xargs tar

The result of this command is a tar with all files that have been modified/added since revision 1792 until HEAD. This command is super useful for incremental releases.

tar -c bins/ | gzip -9 | openssl enc -base64
2011-02-24 22:15:23
User: mweed
Functions: gzip tar

Useful when you have multiple files or binary files that you need to transfer to a different host and scp or the like is unavailable.

To unpack on the destination host copy paste output using the opposite order:

openssl enc -d -base64 | gunzip | tar -x

Terminate openssl input using ^d

Note: gzip is outside of tar because using -z in tar produces lots of extra padding.

tar -cvz /<path>/ | gpg --encrypt --recipient <keyID> > /<backup-path>/backup_`date +%d_%m_%Y`.tar.gz.gpg
2011-02-23 14:19:08
User: kaiserkailua
Functions: gpg tar
Tags: GPG tar.gz

Create a encrypted tar.gz file from a directory on the fly. The encryption is done by GPG with a public key. The resulting filename is tagged with the date of creation. Very usefull for encrypted snapshots of folders.

tar xfzO <backup_name>.tar.gz | mysql -u root <database_name>
2011-02-10 22:18:42
User: alecnmk
Functions: tar

`tar xfzO` extracts to STDOUT which got redirected directly to mysql. Really helpful, when your hard drive can't fit two copies of non-compressed database :)

tar -cvf - $DIR_TO_BACKUP | tee >(md5sum > backup_md5.txt) > /dev/st0 && mt -f /dev/nst0 bsfm 1 && md5sum -c backup_md5.txt < /dev/st0
2011-01-27 20:57:36
User: bugmenot
Functions: md5sum mt tar tee

Backups $DIR_TO_BACKUP into tape, creating on the fly a MD5SUM file of the backup.

Then rewinds one record on tape and checks if it's well written.

find . -type f -mtime +100 -exec tar rvf my.tar --remove-files {} \;
2011-01-26 06:13:19
User: cp
Functions: find tar

tar does not have a -mtime option as find. tar appends all the file to an existing tar file.

wget http://URL/FILE.tar.gz -O - | tar xfz -
2011-01-18 12:17:16
Functions: tar wget

This will uncompress the file while it's being downloaded which makes it much faster

find . -type f -name "*.tar" -printf [%f]\\n -exec tar -tf {} \; | grep -iE "[\[]|<filename>"
2011-01-06 13:01:38
Functions: find grep tar
Tags: find grep tar

A quick find command to identify all TAR files in a given path, extract a list of files contained within the tar, then search for a given string in the filelist. Returns to the user as a list of TAR files found (enclosed in []) followed by any matching files that exist in that archive. TAR can easily be swapped for JAR if required.

git archive --format=tar HEAD | (cd /var/www/ && tar xf -)
2010-12-23 05:50:28
User: ox0spy
Functions: cd tar

in fact, I want to know, how to only get the modified files.

tar -cf ~/out.tar --no-recursion --files-from <(find . -type d)
tar -czvf - /src/dir | ssh remotehost "(cd /dst/dir ; tar -xzvf -)"
Server side: while true; do tar cvzf - ./* | nc -l 2000; done, client side: nc localhost 2000 | tar xvzf -
