How to create command aliases in shell?

Question

How to create command aliases in linux? For example, I'd like to make alias for ssh root@host

Thank you?

As another option you may want to man ssh_config and consider creating a .ssh/config. Using this file you can set default login users for particular hosts. For example if you have a lot of switches that use an 'admin' user, you might add an entry for those so you can just ssh switch1 without having to remember 'admin@'.

Which shell?

Assuming bash, put this kind of thing in your .bashrc:

alias srhost="ssh root@host"

Only for your user, edit your .bashrc

alias srhost="ssh root@host"

To add Alias

alias newcommand="yourcommand -arguments"

To remove Alias

unalias newcommand

I like to create a .bash_aliases file for portability between my systems I use. add this to your .bashrc

if [ -f ~/.bash_aliases ]; then . ~/.bash_aliases fi

you can then add aliases to this file such as

alias psg='ps -auxww|grep'

also after adding a alias you will need to exit/open your terminal so the changes will take affect.

OR try

source ~/.bashrc
