Using the UNIX CLI
All UNIX systems and their derivatives (eg the various flavors of Linux) have a build in command line interface or CLI.
Since all of the compute resources in GENI run some *nix flavor, it is important to be comfortable using the command line.
Some skills you should familiarize yourself with:
- logging into nodes using
ssh
- copying files to and from a node using
scp
- navigating and manipulating the file system (
cp
,mv
,cd
, the meaning of.
and..
) - file permissions (
ls -l
,chmod
,chown
) - use of
sudo
- writing and executing simple shell scripts
- getting help on specific command using
man
and google
Google will help you find many resources for these topics. Here are some resources that might be helpful:
- Linux Command website gives an overview of using the shell
- If you have more time, consider the Introduction to Linux EdX course
