Detailed Description

The PackageKit-command-not-found package installs a handler to bash so that missing commands can be installed, or invalid commands can be corrected.

Benefit to Fedora

This feature will add the same functionality to Fedora as Ubuntu users have had for years.

Scope

This is a very small change in comps, so that the PackageKit-command-not-found package gets included in the default package set. It's already available in Fedora 11, but not installed by default.

How To Test

• Install PackageKit-command-not-found package using yum install PackageKit-command-not-found
• Restart the terminal, or log out and log in again
• Open a terminal (gnome-terminal works well)
• Type 'gedti /boot/grub/grub.conf', and verify output is:

Command not found. Similar command is: 'gedit'

• Ensure the powertop package is removed from the system. Then type 'powertop', and verify output is:

Command not found. Install package 'powertop' to provide command 'powertop'? [N/y]

You can edit system policy by changing the /etc/PackageKit/CommandNotFound.conf file.

User Experience

New users can get the package installed automatically when trying to use a new command. Experienced users can get spelling mistakes in commands automatically fixed.

Dependencies

PackageKit 0.4.x (already in F11)

Contingency Plan

Drop PackageKit-command-not-found from comps, and revert back to doing nothing when the command is not found.
