Parameters

• zip compressed package: specify the zip compressed package to be created;

• File list: Specify the file list to be compressed.

Example

Compress a single file, this will compress the file.txt file into an archive named compressed.zip

zip compressed.zip file.txt

To compress multiple files, the following command will compress file1.txt, file2.txt, and file3.txt into an archive file called compressed.zip.

zip compressed.zip file1.txt file2.txt file3.txt

Compress the entire directory. The -r parameter of the following command indicates recursive compression. This command will compress the folder directory and all its subdirectories and files.

zip -r compressed.zip folder/

Compress files using the maximum compression ratio. The -9 parameter of the following command specifies the maximum compression ratio, although it may take longer to process.

zip -9 compressed.zip file.txt

Create a password-protected zip file. The -e parameter of the following command will prompt the user to enter a password to create an encrypted zip file.

zip -e secure.zip file.txt

Only compress new or changed files, if compressed.zip already exists, the -u parameter will update file.txt in the archive or add it to the archive if it is new

zip -u compressed.zip file.txt

Compress the file but do not preserve the directory structure. The -j parameter will not retain the parent directory folder of file.txt. The location of the file in the zip will be in the root directory.

zip -j compressed.zip folder/file.txt

Pack all files and folders in the directory /home/Blinux/html/ into html.zip in the current directory:

zip -q -r html.zip /home/Blinux/html

The above command operation is to compress files and folders with absolute addresses. The relative path directory for compression is given below. For example, in the Bliux directory, the following operations can be performed to achieve the same effect as above:

zip -q -r html.zip html

For example, in my html directory now, the zip compression command I operate is:

zip -q -r html.zip *

Compress the contents of the example/basic/ directory into the basic.zip compressed package. -x specifies the excluded directory. Note that it will not work without double quotes.

zip -r basic.zip example/basic/ -x "example/basic/node_modules/*" -x "example/basic/build/*" -x "example/basic/coverage/*"

The above is compressed and decompressed, and the content is stored in example/basic/. If you want to store it in the root directory, enter the directory for compression. Currently, no suitable parameters have been found to solve this problem.

cd example/basic/ && zip -r basic.zip . -x "node_modules/*" -x "build/*" -x "coverage/*"

Create a public_html directory and ignore all files and folders, excluding any files including the text backup.

$ zip -r public_html.zip public_html -x *backup*

The httpdocs directory ignores .svn files or git files and creates an archive of all files under the directory.

$ zip -r httpdocs.zip httpdocs --exclude *.svn* --exclude *.git*

All files in the httpdocs directory are ignored and an archive of all files in the directory ending with .log is created.

$ zip -r httpdocs.zip httpdocs --exclude "*.log"
