Shell makes Linux self-extracting files

In Linux systems, sometimes it is necessary to package programs or files into self-extracting files for easy dissemination and installation. This article outlines the basic methods and steps for using shell scripts to create Linux self-extracting files.

1. Prepare the compressed package and Shell script

First, prepare a compressed package containing the programs or files that need to be distributed, and then write a Shell script to perform the decompression and installation steps.

It is assumed here that there is a compressed package file named my_program.tar.gz and a Shell script file named install_script.sh.

2. Merge self-extracting files

Next, use the following command to merge the Shell script file and the compressed package file into a self-extracting file:

cat install_script.shmy_self_extracting_file

This will create a self-extracting file named my_self_extracting_file, which contains the Shell script file and the compressed package file.

3. Set permissions on self-extracting files

Make sure the self-extracting file has executable permissions. Set permissions using the following command:

chmod +x my_self_extracting_file

This will make the self-extracting file executable.

4. Execute the self-extracting file

Now, you can execute the self-extracting file and it will automatically extract and install the program. Use the following command:

./my_self_extracting_file

After execution, the self-extracting file will automatically execute the commands in the Shell script for decompression and installation.

This is a basic example that can be modified and adjusted to suit your needs. In this way, you can more easily create Linux self-extracting files to facilitate distribution and installation of programs or files.

In Linux, you can use a variety of tools to create self-extracting files, one of the commonly used tools is shar. Shar can package multiple files into a self-extracting file. Users only need to run this file to automatically decompress and execute the contents.

To use shar to create self-extracting files, you first need to ensure that shar is installed in your Linux distribution. If it is not installed, you can install it through your package manager. For example, on Debian or Ubuntu, shar can be installed using the following command:

sudo apt-get install sharutils

After the installation is complete, you can use the shar command to package multiple files into a self-extracting file. For example:

shar -my_archive.sh

This will create a self-extracting file named my_archive.sh, which contains three files: file1, file2 and file3. Users only need to run this file and the contents will be automatically decompressed and executed.

In addition to shar, there are other tools that can be used to create self-extracting files, such as using Shell scripts and tar commands. These tools can be selected and used according to needs.
