The '.profile' configuration file is used to configure the bash shell environment and startup programs when a user logs on. This file is specific to the user who has this file in their home directory. It will be read by the shell after reading the system wide profile located at '/etc/profile'. You can unset and change features that that you want. The syntax for this file is the same as the system wide '/etc/profile' configuration file. See the syntax for that file for additional help.
