Command-line Compression Options

jchavenLeave a comment

A comparison of command-line options to compress files using 7-Zip and native commands in Windows and Linux.

For testing I created a Word document of Lorem Ipsum and saved it in Word and PDF formats.

Windows Command Prompt

There is no built-in Windows program able to run in a CMD prompt that does what is wanted.* However, the open-source utility 7za.exe can be copied to any Windows folder without installation and be executed from a batch file.


Command: 7z.exe a -t7z target.7z C:\source\folder\

C:\_Tools\7zip\7za.exe a -t7z C:\Temp\Zip\test.7z C:\Temp\Zip\Files\

Changing the archive type to “zip” causes 7Zip to create a slightly larger archive.

Powershell Core on Windows and Linux

Powershell Core can be installed on both Windows and Linux. The following commands will work with Windows Powershell (deprecated) and Powershell Core (open-source).


# Command syntax:
# Compress-Archive -Path C:\source\folder -DestinationPath C:\target\target.zip
  
Compress-Archive -Path C:\Temp\Zip\files -DestinationPath C:\Temp\Zip\powershell.zip



# Command syntax:
# Compress-Archive -Path C:\source\folder -DestinationPath C:\target\target.zip
  
Compress-Archive -Path /home/joey/temp/zip/files -DestinationPath /home/joey/temp/zip/powershell2.zip

Tar command on Linux and Windows 10 BASH

Linux includes the venerable “tar” command, once used to create tape-archives. Installing the Ubuntu Linux subsystem on Windows 10 brngs this feature to Windows as well.


# Command syntax:
# tar -czvf name-of-archive.tar.gz /path/to/directory-or-file
tar -czvf files.tar.gz /mnt/c/temp/zip/files/

Same command run on Linux Mint.


# Command syntax:
# tar -czvf name-of-archive.tar.gz /path/to/directory-or-file
tar -czvf files2.tar.gz /home/joey/temp/zip/files/

Bonus: Windows Compressed Folders

Just to compare how efficient Windows built-in feature is to the command-line options above.

* There are compression tools built-in to Windows such as compact and makecab that are not covered here.
