Customising your environment

Customise your environment using your .bashrc and .bash_aliases files. I also get most users to source /home/shared/.bashrc and /home/shared/.bash_aliases for helpful scripts. These necessitate the use of some other helpful files.

User profile

First off is the .usr_profile file. I use the information in this to set up useful shortcuts for the shared drive, supercomputer, etc.

# export SH_DRIVE_FOLDER= # your folder on the shared drive, e.g. LILY
# export RJ_PROJECT= # project folder on Raijin
# export RJ_USER= # username on Raijin
# export RJ_HOME_DIR= # home directory on Raijin

Uncomment lines as they apply.

Shared drive credentials

One of the useful commands in .bash_aliases is:

function omara {
    GROUP=`id -gn`
        if [ ! -d "$HOME/mnt/omara/$SH_DRIVE_FOLDER" ]; then
                echo "Mounting omara shared drive."
                sudo mount -w -t cifs //ANUFILE01/Omara $HOME/mnt/omara -o rw,credentials=$HOME/.credentials,gid=$GROUP,file_mode=0777,dir_mode=0777,mfsymlinks
        cd ~/mnt/omara/$SH_DRIVE_FOLDER

This loads the shared drive, if it is not loaded, and goes to your directory. It requires the following:

sudo apt install cifs-utils

You also need to make a mnt directory in home.

mkdir -p mnt/omara

However, it requires your (ANU email) login credentials. You can create a ~/.credentials file and change permissions with chmod 000 .credentials so that other users can’t read it. However, root will always be able to override this. If this makes you feel uncomfortable, you can use the GUI to mount the drive instead.
