Setting environment variables under MAC and using CVS command line

Mac setting environment variables and using the CVS command line:

Set environment variables at the command line:
bogon:~ yanfa$cvsroot=:p Server:username@serveraddress:/home/cvsroot
bogon:~ Yanfa$export Cvsroot
However, this is only valid for the current shell, and if you restart the shell, you must set the environment variable again. The way to make it permanent is:
bogon:~ yanfa$ Vim ~/.bash_profile
Enter Export cvsroot=:p server:username@192.168.0.100:/home/cvsroot
Press ESC and then: Wq Save quit Vim
Let the configuration take effect:
bogon:~ yanfa$ Source ~/.bash_profile

Then CVS login enters the password and logs on to the CVS server.

Get code:
CVS Co directory name (this should be known beforehand)

To commit the modified code:
CVS Commit directory Name

Import all directories and files in the current directory into the warehouse:
CVS Import-m the name on the log message server (preferably the same as the current directory name) anyname1 anyname2
