Commands using tar

Remove annoying improperly packaged files that untar into the incorrect directory.

Example, When you untar and it extracts hundreds of files into the current directory.... bleh.

this bzips a folder and transfers it over the network to "host" at 777k bit/s.

cstream can do a lot more, have a look http://www.cons.org/cracauer/cstream.html#usage

for example:

hehe :)

You can flexibly change file pattern(*.tar.gz) and uncompress command to other job!

Example, remove all files :

for i in *.tar.gz; do rm $i; done

(Just for example, because if you really want to remove file, simply use wildcard like this rm *.tar.gz)

Very simple and useful, you need to change the word "directory" for your directory

Leave it to a proprietary software vendor to turn a cheap and easy parlor trick into a selling point. "Hey guys, why don't we turn our _collection of multiple files_ into a *collection of multiple files*!!" Extract the ^above with this:

^extract on any Unix - no need to install junkware!

(If you must make proprietary software, at least make it do something *new*)

if [ -e windows ]; then use 7-Zip

create an archive of files with access time older than 5 days, and remove original files.

This will update the tarball, adding files that have changed since the last update.

This assumes that the tarball is in the same directory as the files being archived.

N.B. This command can't be used on compressed tarballs.

N.B. This will add the updated files to the tarball, so that the tarball will have two versions of each file. This will make the tarball larger, but doesn't have any other significant effect.

Where foodir is the directory you want to zip up.

gpg's compression is as suitable as gzip's however your backups can now be encrypted.

to extract use:

An easy one but nice to keep in mind.

Clone a partion with tar.

creates a tar.gz with a name like:

backup20090410_173053.tar.gz

of a given directory.

This command will copy files and directories from a remote machine to the local one.

Ensure you are in the local directory you want to populate with the remote files before running the command.

To copy a directory and it's contents, you could:

This is especially useful on *nix'es that don't have 'scp' installed by default.

This is useful for sending data between 2 computers that you have shell access to. Uses tar compression during transfer. Files are compressed & uncompressed automatically. Note the trailing dash on the listening side that makes netcat listen to stdin for data.

on the listening side:

explanation: open netcat to -l listen on -p port 2022, take the data stream and pipe to tar -x extract, -v verbose, -f using file filename - means "stdin"

on the sending side:

explanation: compress all files in current dir using tar -c create, -v verbose, -f using file, - filename - here means "stdout" because we're tar -c instead of tar -x, -w3 wait 3 seconds on stream termination and then end the connection to the listening host name_of_listening_host, on port 2022

I recently found myself with a filesystem I couldn't write to and a bunch of files I had to get the hell out of dodge, preferably not one at a time. This command makes it possible to pack a bunch of files into a single archive and write it to a remote server.

Create backup (.tar.gz) for all first-level directory from current dir.

create tar.bz2 package from files "-type f" modificated today "-mtime -1" in ~/project

Add z to the flags to enable compression.
