How to use ZIP COMMAND in Linux — LinuxTechLab
Zip command in Linux is used for compressing files & folders to reduce their size for the purpose of archival, backup, or for file transfer. Zip command can compress single or multiple files and folders into a single compressed file with extension .zip. We can also compress the whole operations system/file structure into a compressed file.

Let’s first discuss how we can install ZIP utility on our systems.
Installation
To install zip on your system, use the following commands,
Fedora CentOS/RHEL Ubuntu/Mint
$ sudo apt-get install zip
Syntax for using zip command
# zip OPTIONS ARCHIVE.zip FILE1 FILE2 FODER1 FOLDER2
Now let’s discuss some examples for using zip command.
Examples of zip command
Create a zip file
To create a compressed zip file for files or folders, use the following command,
# zip compressed.zip test.txt test2.txt *.html
Zip a directory
To create zip file for a complete directory with all the files and folders inside, we can use the following command,
# zip -r compressed.zip test_folder
Create a password-protected zip file
To create a zip file that is protected with a password, we can use the following command,
# zip -e compressed.zip test.txt test2.txt *.html
You will then be asked to enter a password to protect the zip file.
Add files to a zip file
To add new files or update existing files to a created zip file, we can use the option ‘u’,
# zip -u compressed.zip new_file.txt
If the file already exists on the zip, then the old file will be overwritten.
Delete a file from zip file
If we wish to remove a file from already created zip, then we can use the option ‘d’,
# zip -d compress.zip file1.txt
Delete original files after zip creation
We can also make zip command to delete the original files from which the zip file was created by using the option ‘m’,
# zip -m compressed.zip test.txt test2.txt *.html
Using compression level in zip
Zip provides compression level from 0 to 9 with 0 being no compression at all & 9 being the most compressed, default compression is 6. We can mention the compression level as follows,
# zip -8 compressed.zip test.txt test2.txt *.html
Splitting zip file based on size
By default, a single zip file is created but we can also create multiple zip files i.e. splitting zip files based on the size of zip file. For example, we can create zip file with a zip file being a maximum of 2 GB with the help of the following command,
# zip -s 2g compressed.zip test.txt test2.txt *.html
