How to [tar and] compress marked files in Emacs

Question

In dired+ in Emacs 23.2.1 in the Debian Squeeze variant, I selected four files with * , and then pressed Z to compress them. I answered y at the invitation and saw some status updates in the mini-buffer. Where to find the compressed file? I tested one file ( Cu Z ), and Emacs ran gzip in one file and made it a .gz file. How do I [tar and] compress marked files in Emacs?

(To forestall any philosophical or methodological discussions about tar, gzip, other formats and archives in general, all I want is four files that will be stored in one file as compressed data. If this can be achieved using tar and gzip or compressing each directly to the archive does not matter.)

Answer 1

If dired+ is something like dired , you can mark files with m and then press ! (to run the shell command in the marked files) and specify the command as tar -czf foo.tar.gz * ( * - a special marker that is replaced by the names of the marked files).

Answer 2

You can also archive files by simply marking them and copying them to the archive.

For example, mark several files in standby mode and select mx dired-do-copy .

When prompted for the destination, enter test.zip . Files will be automatically added to the zip archive.

You can also unzip files by selecting them in standby mode and issuing the dired-do-extract command

To set this, view the following variables: Dired to backup ALIST Dired-extract-ALIST

Here is my installation, which has served me for many years ...

 ;; dired-a provides support functions, including archiving, for dired (load "dired-a") ;; Alist with information how to add files to an archive (from dired-a) ;; Each element has the form (REGEXP ADD-CMD NEW-CMD).

Answer 3

Platform: Ubuntu

Requirements

System:
sudo apt-get install atool

Emacs:
Mx package packages
Cs dired-atool RET
I
x

Decision

1) Mark the files in the downloaded buffer.
2) Mx dired-atool-do-pack Make sure the shell file name is set to "/ bin / bash".

Answer 4

In response to the last question, another tool that can be used to create a compressed tar file from dired is pack . Mark the files you want and run pack-dired-do-pack , specifying whatever.tar.gz as the name of the output file.
