I type in "set" and "env" command and find those variables but they are not setted in ~/.bash_profile so I suppose those things was configed in somewhere in /etc/.
Am I right?
I am new to bash.
It means if there is a file called .bashrc in user's home folder, then source it.
source it - means run commands in that script, but instead creating a new subshell, execute them in present shell. so whatever you have set in script are now available to current shell (something like logout-login or refresh).
-f = if file exists
. = sourcing (you can also use 'source' instead of '.' both are same)

It looks that there are lots of parameters can be list in [conditions], like -f -z -n, does all these are parameters from command "test"?
