Softwares in USC installs one after the other, is there any way to make more than one sofware install at the same time?
If I understand your question correctly you want to install more than one package at once. I suggest you use "synaptic package manager". At the command prompt,
1. sudo apt-get install synaptic
2. sudo synaptic
3. in synaptic, you can choose whatever packages you want to install. All packages will be installed afterwards.
