[SOLVED] Can I assign an alias to a environment variable?

[TwoFistedJustice]

I have discovered the simplicity of the command line for rotating my monitors. It' s a lot faster than going through the GUI. BUT...

I hate typing out the monitor names, e.g. "DP-2-3"

Is there a safe way to assign an alias to that environment variable?

Could I safely do something like

mon2=$DP-2-3

maybe in .bashrc or .bash_profile?

This is one of those areas where I have just enough understanding to get myself into a fix, which I'd rather avoid.

Yes, there's many ways to do this.

I would just define aliases for the complete commands, f. ex.

alias d2='foo dp-2'

but if you really want to use an environment variable, say BAR,

alias d2='foo $BAR'

the file .bash_aliases is the conventional place; it gets sourced by .bashrc by default, if it exists.

Thanks for the idea jlittle!

Turns out it doesn't work if you put the "$" in.

This is what I ended up doing:

in .bash_aliases

#Samsung 23"
alias mon2="xrandr --output DP-2-2 --rotate"

#HP 19"
alias mon3="xrandr --output DP-2-3 --rotate"

now rotate my display in terminal

mon3 normal

or

mon3 left
