How can I pay my gratitude to my linux os?

Edit your .bashrc file and add it in there:

vi ~/.bashrc

then simply add all your aliases in there like so:

# .bashrc

# User specific aliases and functions
alias l='ls -hAlF | more'
alias la='ls -hAlF'
alias c='clear'
alias Thanks='echo You are welcome'
alias thanks='echo \    ...bitteschön \;\)'

# Source global definitions
if  -f /etc/bashrc ]; then
        . /etc/bashrc
fi

You will have to logout and back in again for it to take effect though :).
