Linux zip folder recursively

The original size of the source location was

which after compression is 842M so we saved

We increase the compression level to -9 and create a zip folder which is considered as the highest or maximum compression level.

Now with higher level of compression, zip took additional 3 seconds to complete the compression but we only save 1MB overall in our archive so the advantage was not very high compared to the time we invested.

12. How to copy files between two zip archives

You can also copy files from one zip archive to another using -U or —copy-entries argument without extracting.

Also requires the —out option to specify a different output file than the input archive.

Here in this Linux zip command example we copy files between two zip archives, I have an input archive with below content

I will copy one of the rpm to another new archive

Verify the content of the output_archive

If no input files appear on the command line and —out is used, copy mode is assumed:

13. Linux zip directory and remove files from zip archive

In Linux zip directory and using -d or —delete directive you can delete or remove files from zip archive.

Let us take this Linux zip command example. Here I have a Linux zip archive with below content

So to remove files from zip archive , I will remove two files from the existing zip archive without unzip to directory

Verify the content of the archive

14. Linux zip folder and preserve symbolic links

For UNIX and VMS (V8.3 and later) use -y or —symlinks , create a zip folder and store and preserve symbolic links in zip archive.

This can avoid multiple copies of files being included in the archive as zip re curses the directory trees and accesses files directly and by links.

Let’s take this Linux zip command example. Here I have created a dummy file inside my root’s home folder and added some content.

Create a symlink to this dummy file

Verify the symlink

Next create a zip folder including symlink using -y or —symlinks argument to make zip preserve symbolic links

I will create a dummy location to extract the archive and verify the symlink

Unzip to directory using unzip command

Unzip to directory the newly created archive using unzip to make sure zip was able to preserve and store symbolic links

So with -y we make zip preserve symbolic links

Next verify the symlink content.

15. How to create a zip file and compress with bzip2

You can create a zip file with bzip2 compression. Set the default compression method using -Z or —compression-method . Currently the main methods supported by zip are store and deflate. Compression method can be set to:

• store — Setting the compression method to store forces zip to store entries with no compression. This is generally faster than compressing entries, but results in no space savings. This is the same as using -0 (compression level zero).
• deflate — This is the default method for zip. If zip determines that storing is better than deflation, the entry will be stored instead.
• bzip2 — If bzip2 support is compiled in, this compression method also becomes available.

Extract content using unzip command

Extract the content using unzip to directory

16. How to zip a folder and later split zip archive

• How to zip a folder and enable creating a split zip archive and set the split size using -s or —split-size .
• A split zip archive in Linux and Unix is an archive that could be split over many files.
• As the zip archive is created, if the size of the archive reaches the specified split size, that split is closed and the next split opened.
• In general all splits but the last will be the split size and the last will be whatever is left .
• If the entire archive is smaller than the split size a single-file archive is created.
• Split size is a number optionally followed by a multiplier.
• Currently the number must be an integer.
• The multiplier can currently be one of k (kilobytes), m (megabytes), g (gigabytes), or t (terabytes).
• As 64k is the minimum split size, numbers without multipliers default to megabytes

Let’s use this Linux zip command example to create a zip folder with split enable. I have Packages directory with files having size of 902MB. Here I will create zip archive

The last file as you see is of 36MB while all the other archive is of 200MB which we had used as the split size

Lastly I hope the steps from the article to compress and archive using zip command and cover scenarios life zip multiple files and folders, zip all files except some files and folders, compress directory and preserve symbolic links, remove files from zip archive, zip delete original files in Linux and Unix was helpful. So, let me know your suggestions and feedback using the comment section.

Zip all files in directory?

Is there a way to zip all files in a given directory with the zip command? I’ve heard of using *.* , but I want it to work for extensionless files, too.

5 Answers 5

You can just use * ; there is no need for *.* . File extensions are not special on Unix. * matches zero or more characters—including a dot. So it matches foo.png , because that’s zero or more characters (seven, to be exact).

Note that * by default doesn’t match files beginning with a dot (neither does *.* ). This is often what you want. If not, in bash, if you shopt -s dotglob it will (but will still exclude . and .. ). Other shells have different ways (or none at all) of including dotfiles.

Alternatively, zip also has a -r (recursive) option to do entire directory trees at once (and not have to worry about the dotfile problem):

where mydir is the directory containing your files. Note that the produced zip will contain the directory structure as well as the files. As peterph points out in his comment, this is usually seen as a good thing: extracting the zip will neatly store all the extracted files in one subdirectory.

You can also tell zip to not store the paths with the -j / —junk-paths option.

The zip command comes with documentation telling you about all of its (many) options; type man zip to see that documentation. This isn’t unique to zip; you can get documentation for most commands this way.

How can I recursively zip files in their own folder?

I have the following directory structure:

In Linux I want to zip files (excluding folders) in every directory and create a 7z (or zip) archive in each folder resulting the following:

Following script works in the first directory but not in the sub-directories :

How can I achieve this?

2 Answers 2

If you want to use 7z , the tricky part seems to be persuading it not to recurse; the documentation’s indicated -r- switch appears to be non-functional, and the suggested workaround from the software’s author is to exclude subdirectories with the wildcard expression -x!*/

where for example we can check that Folder2.7z contains only its own folder’s files using

Note: !*/ may require additional escaping in environments (such as the interactive bash shell) where ! is a history expansion operator.

This is untested code, only used with ‘echo’, since I don’t like to end with multiple zip files. And it is phantasy zip syntax, since I don’t know 7za, but I will explain:

The script ad-hoc.sh has to be adressed with an absolute path and should not be in the current path, to not affect the outcome, but it might be in the parentdir:

and, if not made executable, be explicitly invoked:

Find shall look in the current dir, only for files of type d (dirs), where to -execute a bashscript with parameter <>, the directory found.

Ok — what is the ad-hoc.sh, we execute in the dir and subdirs? It’s another find:

-maxdepth 1 prevents find to search subdirs, -type says to just operate on files. -exec launches a command, for testing «echo zip . «, but if it looks promising (you do backups often, don’t you?), you — well, here starts my pseudo code: -o:= -output «$PWD.zip», and <> + is the file list.

Every file with extension is a regular file, and every file without is a directory or a symlink to a dir (up3).

The <> has to be the last element of a find -exec command before the terminating «;» or +, so you have to build your 7z-command accordingly.
