how do I change default text viewer?

also, in which file can I access/edit from terminal the bash options and general linux options?

in Ubuntu 12.04

~/.bash_profile and ~/.bashrc and sometimes ~/.bash_aliases

See man bash and look at the section INVOCATION. It will tell you the process of how bash loads its configuration files.

Make sure, are you asking for text viewer or text editor?

Are you asking about shell or envorinmental variables? If so, then by editing the .bashrc (but I won't recommend doing this). Instead you can set value of any variable using following syntax in bash:
<variable_name>=<value>
export <variable_name>
Eg. history=500
export history
Then to check value assigned to any variable, use either:
echo $<variable_name>
Or for full listing, invoke cmd:
env

If you find a text file in Nautilus, right click, and choose "properties" you have an "open with" option. At least, you do in Gnome; I'm never too sure what Unity gets up to!
