Powerful apt-GET command (Summary)

I. the most convenient non-Apt-Get tool for management software in Ubuntu does not belong to anyone. Its common usage is sorted out for future reference (see man apt-Get for details ):

1. Update the source. Do this before upgrading the software and system ~ (Source directory:/Etc/APT/sources. List)

 
Sudo apt-Get update
 

2. Update the installed package to the latest version (skip this step if it is the latest version)

 
Sudo apt-Get upgrade
 

3.Upgrading the system is risky! At this time, APT will first upgrade important packages. If there is a conflict, some secondary packages may be deleted (see man apt_preferences)

 
Sudo apt-Get dist-Upgrade
 

4. Install (upgrade) one or more software. You can also specify the version number to install a specific software version. You can also use regular expression matching for PAC.

 
Sudo apt-Get install pac1 pac2 pac3...
 

5. Delete the software in the same way as install. The configuration file will be retained.

 
Sudo apt-Get remove pac1 pac2 pac3...
 

6. The configuration file will also be deleted in the same way as remove (this is more thorough)

 
Sudo apt-Get purge pac1 pac2 pac3...
 

7. Get the source code to the current folder.

 
Sudo apt-Get source Pac
 

8.Install the relevant compiling environment

Sudo apt-Get build-dep Pac
 

9. Update cache,Check for any corrupted dependency

 
Sudo apt-Get check
 

10. Download the binary package to the current directory.

 
Sudo apt-Get download Pac
 

11. clears out the local repository of retrieved package files to release disk space

 
Sudo apt-Get clean
 

12. clears out the local repository of retrieved package files, clear undownloadable and useless packages, and release disk space

 
Sudo apt-Get autoclean
 

13. Remove packages that were automatically installed to satisfy dependencies for some packages and that are no more needed.

 
Sudo apt-Get autoremove
 

14. Other parameters, such as-y-m-F, are combined to provide more powerful functions. We will not list them one by one. Update the system first!
