Description
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.
By default ShellCheck can only check non-hidden files under /home, to make
ShellCheck be able to check files under /media and /run/media you must
connect it to the removable-media interface manually:
# snap connect shellcheck:removable-media
