Introduction to Linux Package Editor
software packages. A package consists of an archive of files along with information
about the package, including name, version, and description.
Information about all installed packages and the files that they create or change is
stored in the RPM database on the Linux computer. RPM contains a powerful set of query
capabilities to obtain information about packages, such as the files that make up a
package, what files are installed, and which files are configuration or documentation
files.
An RPM file is a package file that contains software that will be installed using RPM.
About the Shell File
The Linux project file (.LPR) compiles to a shell file (.SH), which acts as a “wrapper” to
the RPM and provides additional functionality.
Following is a representation of the compiled shell file.
Warning
Only create the shell file by using the Build Installation Package command. Editing the
shell file manually will cause the installation to fail.
