I think it would be nice if someone adds a link to a Windows version of dd. I am looking for a version which has all the options of the Unix dd. Can anybody help me?
The tar Command The tar i. An archive is a single file that contains any number of individual files plus information to allow them to be restored to their original form by one or more extraction programs.
Archives are convenient for storing files as well as for for transmitting data and distributing programs. Moreover, they are very easy to work with, often much more so than dealing with large numbers of individual files.
Although tar was originally designed for backups on magnetic tape, it can now be used to create archive files anywhere on a filesystem. Archives that have been created with tar are commonly referred to as tarballs.
Unlike some other archiving programs, and consistent with the Unix philosophy that each individual program should be designed to do only one thing but do it well, tar does not perform compression.
However, it is very easy to compress archives created with tar by using specialized compression utilities. Unlike many commands, tar requires the use of at least one optionand usually two or more are necessary.
The former instructs tar to create an archive and the latter indicates that the next argument i. Thus, for example, the following would create an archive file called file.
It is necessary, however, that the -f option be the final option in a sequence of contiguous, single-letter options; otherwise, the system will become confused as to the desired name for the new file and will use the next option in the sequence as the name.
In such case, the above example would become tar -cvf file. The result is recursive; that is, it includes all objects e. For example, the contents of two directories named dir1 and dir2 could be archived into a file named dir. The following example uses the star wildcard i.
However, they can be removed when using tar by adding the --remove-files option. As it has no compression and decompression capabilities of its own, tar is commonly used in combination with an external compression utility. A very handy feature of the GNU version which is standard on Linux is the availability of options that will cause standard compression programs to compress a new archive file as soon as it has been created.
They are -j for bzip2-z for gzip and -Z for compress. Thus, for example, the following would create an archive named files. However, before doing this, there are several steps that should be taken. One is to confirm that sufficient space is available on the hard disk drive HDD.
Another is to move to an empty directory which usually involves creating one with an appropriate name to prevent the reconstituted files from cluttering up the current directory and overwriting any files or directories with same names that are in it.
In addition, if the archive has been compressed, it must first be decompressed using the appropriate decompression program which can usually be determined by the filename extension. In order to unpack a tar file, the -x for extract and -f options are required.
It is also common to add the -v option to provide a running listing of the files being unpacked. Thus, for example, to unpack the archive file. Thus, for instance, the following would decompress and extract the contents of the compressed archive files.
As is always the case with tar, it is also necessary to use the -f option to indicate that the following string i. For example, the following would append a file named file7 to file.
However, this is different from an extraction, as copies of the removed files are not made and placed in the current directory. Thus, for example, the files file1 and file2 can be removed from file. Thus, the following would list the contents of file. Another is --version, which shows the version number for the installed tar program as well as its copyright information.
OK, I Understand. It also may help investigating default options that effect the creation of a tar archive. Defaults to some options are provided by tar is they are not expressed on the command line at run time. The default values are set when the program is compiled. Chromeos can't benjaminpohle.com files, just like it can't benjaminpohle.com files.
You'll need a Linux or windows pc to access the file. You could open it via Crouton on your chromebook or another pc and then load the actual mp3 file onto your Chromebook. At my last job I actually got to use the real tar command, in its original meaning: "tape archive".

The tar (i.e., tape archive) Thus, for instance, the following would decompress and extract the contents of the compressed archive benjaminpohle.com2 that was created in an above example: tar -xjvf benjaminpohle.com2.
Files can be added to an existing archive using the -r option.
