Editing .bashrc file on econstat6
The .bashrc file is a script that runs automatically when the econstat6 server is accessed. There may be times when I need to edit it. For example, following Ben Butler’s instructions, I recently edited it so that Julia 1.3 loads automatically when I access the server. I also recently edited the file to set the environment variable JULIA_NUM_THREADS to 48 (which is the number of CPUs on econstat6).
Viewing .bashrc
The .bashrc file is a hidden file stored in the home directory /home/glusterfs/asyadav. To see that it is indeed there, in the home directory type
ls -la ~/ | moreTo view the contents of the file type
cat .bashrcThe commands at the bottom of the file were added by me.
Editing .bashrc
To edit .bashrc we use a tool called nano.
To open the file in the nano editor type
nano ~/.bashrcThen edit the file as you would any other text file. BE VERY CAREFUL NOT TO BREAK ANYTHING!
Once you’re done editing press CTRL+O to save. To exit the nano editor press CTRL+X then Enter when prompted to retain the name of the file.
