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