The apt-get is an important command
which works with Advavced Packaging Tool(APT) for updating package
list,upgrading package list,installing new software etc.
The packaging system maintains one
database which contains information of which packages are installed,which are
not installed and which are available to install.The apt-get uses this database
to install the various packages.
Update the list of available packages : sudo
apt-get update
Install any particular package : sudo apt-get install packagename
Reinstall any particular package : sudo
apt-get --reinstall install packagename
Remove any particular package : sudo
apt-get remove packagename
Upgrade the packages : sudo apt-get -u upgrade
Upgrade any particular package : sudo apt-get -u install packagename
Search any particular package : sudo
apt-cache search packagename
