ShellRef

ShellRef is an offline reference app for Bash, Zsh, Unix command-line tools, and terminal editors. It explains the ideas behind shell syntax and scripting, then backs them up with examples, tables, and safety notes—from your first variables and redirects to process control, shell configuration, and editor workflows. It’s for people learning the command line and experienced users who want a dependable refresher on iPhone or a second screen beside their terminal on iPad.
