Command to extract a 7z file in Linux
There are several command options and parameters you can use to extract a 7z file in Linux. Let’s explore each of them:
1. 7z x file.7z
The 7z x command is used to extract a 7z file. Simply replace file.7z with the name of your 7z file. This command will extract the contents of the 7z file to the current directory.
For example, to extract a file named archive.7z, you would use the following command:
7z x archive.7z
This command will extract the contents of archive.7z to the current directory.
2. 7z e file.7z
The 7z e command is similar to 7z x, but it extracts the files without preserving the directory structure. This means that all the files will be extracted to the current directory without any subdirectories.
For example, to extract a file named archive.7z using the 7z e command, you would use the following command:
7z e archive.7z
This command will extract all the files from archive.7z to the current directory without preserving the directory structure.
3. 7z x file.7z -o /path/to/extract
The -o option is used to specify the output directory for the extracted files. By default, the extracted files are placed in the current directory. However, you can use the -o option followed by the desired output directory to extract the files to a specific location.
For example, to extract a file named archive.7z to the /home/user/extract directory, you would use the following command:
7z x archive.7z -o /home/user/extract
This command will extract the contents of archive.7z to the /home/user/extract directory.
4. 7z e file.7z -o /path/to/extract
The 7z e command also supports the -o option to specify the output directory. Using the 7z e command with the -o option will extract the files without preserving the directory structure, similar to the previous example.
For example, to extract a file named archive.7z to the /home/user/extract directory using the 7z e command, you would use the following command:
7z e archive.7z -o /home/user/extract

5. 7z x file.7z -o/path/to/extract
The -o option can also be used without a space between the option and the output directory. This allows you to specify the output directory directly after the -o option, without the need for a space.
For example, to extract a file named archive.7z to the /home/user/extract directory using the -o option without a space, you would use the following command:
7z x archive.7z -o/home/user/extract
This command will extract the contents of archive.7z to the /home/user/extract directory.
6. 7z e file.7z -o/path/to/extract
The 7z e command also supports the -o option without a space between the option and the output directory. This allows you to specify the output directory directly after the -o option, similar to the previous example.
For example, to extract a file named archive.7z to the /home/user/extract directory using the 7z e command and the -o option without a space, you would use the following command:
7z e archive.7z -o/home/user/extract
This command will extract all the files from archive.7z to the /home/user/extract directory without preserving the directory structure.
7. 7z x file.7z -o/path/to/extract/ -r
The -r option is used to extract files recursively from subdirectories within the 7z file. This means that all files and directories within the 7z file will be extracted, including files in subdirectories.
For example, to extract a file named archive.7z to the /home/user/extract directory and extract files recursively, you would use the following command:
7z x archive.7z -o/home/user/extract/ -r
This command will extract all the files and directories from archive.7z to the /home/user/extract directory, including files in subdirectories.
8. 7z e file.7z -o/path/to/extract/ -r
The 7z e command also supports the -r option to extract files recursively. Using the 7z e command with the -r option will extract all files and directories from the 7z file, similar to the previous example.
For example, to extract a file named archive.7z to the /home/user/extract directory and extract files recursively using the 7z e command, you would use the following command:
7z e archive.7z -o/home/user/extract/ -r
This command will extract all the files and directories from archive.7z to the /home/user/extract directory, including files in subdirectories.
9. 7z x file.7z -o/path/to/extract/ -r -y
The -y option is used to automatically answer “yes” to any prompts during the extraction process. This can be useful when extracting multiple files or when running extraction commands in a script or batch file.
For example, to extract a file named archive.7z to the /home/user/extract directory, extract files recursively, and automatically answer “yes” to any prompts, you would use the following command:
7z x archive.7z -o/home/user/extract/ -r -y

The 7z e command also supports the -y option to automatically answer “yes” to any prompts. Using the 7z e command with the -y option will extract all files and directories from the 7z file, similar to the previous example.
For example, to extract a file named archive.7z to the /home/user/extract directory, extract files recursively, and automatically answer “yes” to any prompts using the 7z e command, you would use the following command:
7z e archive.7z -o/home/user/extract/ -r -y
This command will extract all the files and directories from archive.7z to the /home/user/extract directory, including files in subdirectories, without prompting for confirmation.
11. 7z x file.7z -o/path/to/extract/ -r -y -p
The -p option is used to specify a password for encrypted 7z files. If the 7z file is password-protected, you can use the -p option followed by the password to extract the files.
For example, to extract a password-protected file named archive.7z to the /home/user/extract directory, extract files recursively, automatically answer “yes” to any prompts, and provide the password during extraction, you would use the following command:
7z x archive.7z -o/home/user/extract/ -r -y -p
This command will prompt you to enter the password for the encrypted 7z file and then extract all the files and directories from archive.7z to the /home/user/extract directory.
12. 7z e file.7z -o/path/to/extract/ -r -y -p
The 7z e command also supports the -p option to specify a password for encrypted 7z files. Using the 7z e command with the -p option will prompt you to enter the password and then extract all files and directories from the 7z file, similar to the previous example.
