# RPM Packaging guide 

https://rpm-packaging-guide.github.io/

This guide seems a little more detailed as compared to the IBM tutorial. More core concepts, and less copy pasta.

Project list:

|Program name| Purpose|
| ------------- |-------------|
| hello-world | Your first rpm package. Creates a hello world script and rpm from one spec file.|

# Using the install command

`install` as a command is provided to the system through the GNU Core utilities. It places an artifact to the specified directory in the filesystem with a specified set of permissions.

The below command is an example of using the install command to place the bello shell script we have in the `/usr/bin` directory with full permissions to the user, and read+execute permissions to the group and all users. 

```bash
sudo install -m 0755 bello /usr/bin/bello
```

We can add an install directive to our make files so that we can run `make install`. _note make files are usually written by the developer and not the packager_


# Tips and Tricks

An RPM is a CPIO archive. You can view it's contents without installing it by:

```bash
rpm2cpio <your_package>.rpm | cpio -ivmd
```
