To get more detailed package information (e.g., version number, check sums, size, installed size, category)

along with the short description, use the

show sub-command, as shown below:

moxa@Moxa:~$ sudo apt-cache show vim

Check Dependencies for Specific Packages

Use the showpkg sub command to check the dependencies for particular software packages, and whether

those dependent packages are installed or not. For example, use the

showpkg command along with the

package name as shown below:

moxa@Moxa:~$ sudo apt-cache showpkg vim

Check Cache Statistics

The stats sub command displays the overall statistics of the cache. For example, the following command will

show the complete package information of all packages found in the cache:

moxa@Moxa:~$ sudo apt-cache stats

Update System Packages

The update command is used to resynchronize the package index files from the their sources specified in the

/etc/apt/sources.list file. The updated commands will fetch the packages from their locations and update

the packages to the newer version.

moxa@Moxa:~$ sudo apt-get update

Install or Upgrade Specific Packages

Use the install sub command to install or upgrade one or more packages.

moxa@Moxa:~$ sudo apt-get install vim

Upgrade All Software Packages

The upgrade command is used to upgrade all software packages currently installed on the system.

moxa@Moxa:~$ sudo apt-get upgrade

Install Multiple Packages

You can add more than one package name along with the command in order to install multiple packages at the

same time. For example, the following command will install packages “vim” and “goaccess”:

moxa@Moxa:~$ sudo apt-get install vim goaccess

Install Packages Without Upgrading

Use the –no-upgrade sub command to prevent the installed packages from being upgraded.

moxa@Moxa:~$ sudo apt-get install packageName --no-upgrade
