Bash Shell Scripting (PDF) (PPT)
The default shell on many Linux systems is bash. Bash shell scripting provides a method for automating common tasks on Linux systems (such as Helix and Biowulf), including transferring and parsing files, creating qsub and swarm scripts, pipelining tasks, and monitoring jobs. Click here for a set of bash scripts for simulating a workflow.
