ShellCheck is a shell script static analysis tool

ShellCheck is a 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.

This is free and open source software.
