bash: Interactive

An interactive field guide to the HPC command line

Navigation, head/wc/cat, input/output redirection, quoting rules, and fixes for common beginner errors, with copyable examples and two interactive simulators.

The guide below is fully interactive: search with //, copy any example, try the redirection visualizer and the quoting playground. This is the interactive version of the bash: Advanced commands module created with Claude AI.

For the best experience, open it full screen.
