How to create a debian deb file
We can make a simple script and save it as hello-world.sh.
#!/bin/bash
echo "Hello World!"
Then you we can create a directory and call it hello-world, and create the directory where we want the script to be installed, and move the script there.
mkdir -p hello-world/usr/bin
mv hello-world.sh hello-world/usr/bin/
After we need to create the control file
mkdir -p hello-world/DEBIAN
touch hello-world/DEBIAN/control
cat <<EOT >> hello-world/DEBIAN/control
Package: hello-world
Version: 1.0.0
Maintainer: Flaxplax
Architecture: amd64
Section: misc
Priority: optional
Description: Hello world script
EOT
Now we will change permissions on the directory and build the deb package
chmod 755 -R hello-world
dpkg-deb --build hello-world
We can now install the deb package and run the program
dpkg -i hello-world.deb
hello-world.sh
Hello World!
