By sourcing the file, you are executing the commands in as though they existed in the current file, .bashrc in this case.This has the effect of setting the environment variables for the current shell as you desire.# /etc/bashrc # System wide functions and aliases # Environment stuff goes in /etc/profile # By default, we want this to get set. if [ $UID -gt 99 ] && [ "`id -gn`" = "`id -un`" ]; then umask 002 else umask 022 fi # are we an interactive shell?Other command directories can be added to this list of directories by adding them to the PATH variable.You can choose to make a user-specified directory available for a single user or the entire system, depending on your company's requirements. Type the line: PATH=/path/to/command/directory:$PATH in the file.Replace "/path/to/command/directory" with the exact path to the directory you want to add.
Typically these commands are located in the /usr/sbin, usr/bin and /sbin, and /bin directories.
