deb-postinst - Linux
Overview
deb-postinst executes a post-installation script when a Debian package is installed. It is primarily used to perform additional configuration steps or system modifications that cannot be handled by the package configuration management system (dpkg).
Syntax
deb-postinst <package> <version>
Options/Flags
None
Examples
Simple Usage
deb-postinst my-package 1.2.3
This command will execute the post-installation script for the package my-package
after it has been installed with version 1.2.3
.
Complex Usage
deb-postinst my-package 1.2.3 --force
The --force
option forces the execution of the post-installation script even if the previous installation failed.
Common Issues
- Error: post-installation script not found – This occurs when the package does not contain a post-installation script. Check the package contents or contact the package maintainer.
Integration
deb-postinst can be combined with other package management commands to automate installation tasks. For example:
dpkg -i my-package.deb && deb-postinst my-package 1.2.3
This command installs the my-package.deb
package and then executes the post-installation script.
