| 6 | apt-get - Cover for dpkg |
| 7 | |
| 8 | This is an allout cover for dpkg implementing a safer front end. It is |
| 9 | based largely on libapt-pkg. |
| 10 | |
| 11 | The syntax is different, |
| 12 | apt-get [opt] command [things] |
| 13 | Where command is: |
| 14 | update - Resyncronize the package files from their sources |
| 15 | upgrade - Smart-Download the newest versions of all packages |
| 16 | dselect-upgrade - Follows dselect's changes to the Status: field |
| 17 | and installes new and removes old packages |
| 18 | dist-upgrade - Powerfull upgrader designed to handle the issues with |
| 19 | a new distribution. |
| 20 | install - Download and install a given package (by name, not by .deb) |
| 21 | check - Update the package cache and check for broken packages |
| 22 | clean - Erase the .debs downloaded to /var/cache/apt/archives and |
| 23 | the partial dir too |
