Linting / code style

• for general shell linting, use shuck or shellcheck`
• for bash, use checkbashism
  • see bash.md for more details on bashism
• Also: shfmt

Shellcheck fixing support

Still no native automitic fixing but as a workaround:

shellcheck -f diff test.sh |git apply

For multiple files:

find . -type f -iname '*.sh' -printf '%P\0' | xargs -0 shellcheck -f diff | git apply

There's also an example to use parallel jobs.
