I need to run these commands very often:

sudo apt-get install <package>
sudo apt-get remove <package>

Can I make it simple like:

install <package>
remove  <package>

I think I need to write a function like this:

function install(){
sudo apt-get install <package>

...and then need to copy paste to some location i don't know. Can anyone tell me how can I make such an install <package> command available all the time after boot?

Use shell aliases, they won't interfere with other scripts/commands, they are only replaced when the command has been typed interactively:

alias install="sudo apt-get install"

You may place this in your shell configuration file (~/.bashrc for example) and it will be defined in all your shell sessions.

You can use $1 (and so on for Nth) to refer to the first argument passed to a function or $* to refer to all of them. The $@ format refers to all the arguments passed but will expand into separate words:

function install(){
    sudo apt-get install "$@"

You could then put this in your ~/.bashrc file so that it will be available every time you login.

In this case, a simple alias might also do the trick:

$ alias install="sudo apt-get install"

That can also be placed in the same file.

alias will be temporary ? – mr_eclair Aug 2 '11 at 14:29
@mr_eclair: As I mentioned, you can place aliases in ~/.bashrc in the same way so that you have them every time you pull up a bash shell. – Caleb Aug 2 '11 at 14:33
