Active Members Fi8sVrs Posted May 31, 2018 Active Members Report Posted May 31, 2018 ShellCheck is a GPLv3 tool that gives warnings and suggestions for bash/sh shell scripts: The goals of ShellCheck are To point out and clarify typical beginner's syntax issues that cause a shell to give cryptic error messages. To point out and clarify typical intermediate level semantic problems that cause a shell to behave strangely and counter-intuitively. To point out subtle caveats, corner cases and pitfalls that may cause an advanced user's otherwise working script to fail under future circumstances. See the gallery of bad code for examples of what ShellCheck can help you identify! Installing How to use There are a number of ways to use ShellCheck!
