BRC Cluster Workshop

There are a number of good resources on the web. Here's one of them:

Note: this does not apply to users who log in with their Unity Id and password.

passwd

There is a 12-character minimum length requirement on the cluster.

pwd - print working directory
ls - list files
cd - change directory
less - file pager
file - describes type of a file

cp - copy 
mv - move (rename)
rm - remove (delete)
mkdir - make directory
rmdir - remove directory

Choose an editor:

nano
vi
emacs

#!/bin/bash
...

Make a script file “executable”:

chmod u+x scriptname

man COMMAND
man ls

Save output from a command to file.

ls > file.txt

This lets you run multiple terminals that are immune to “hang-ups” (network errors) and can remain active even after you log out. You “detach” from the terminal and then re-attach after logging back in.
