Editing CommunityData:Hyak (section)

== Setting up your Hyak environment ==

Everybody who uses Hyak as part of our group '''must''' add the following line to their <code>~/.bashrc</code> file on Hyak:

<source lang='bash'>
source /gscratch/comdata/env/cdsc_klone_bashrc
</source>

If you don't have a preferred terminal-style text editor, you might start with nano -- <code>nano ~/.bashrc</code>, arrow down, paste in the 'source....' text from above, then ^O to save and ^X to exit. You'll know you were successful when you type <code>more ~/.bashrc</code> and see the 'source....' line at the bottom of the file. Copious information about use of a terminal-style text editor is available online -- common options include nano (basic), emacs (tons of features), and vim (fast).

This line will load scripts that will initialize a good data science environment and set the [[:wikipedia:umask|umask]] so that the files and directories you create are readable by others in the group. '''Please do this immediately before you do any other work on Hyak.''' When you are done, you can reload the shell by logging out and back into Hyak or by running <code lang="bash">exec bash</code>.
