It is then good to fix the other harmless issues in order to spot "real" ones later. Here, two categories of warnings are now ignored: - SC2317: Command appears to be unreachable. The cleanup() function is invoked indirectly via the EXIT trap. - SC2086: Double quote to prevent globbing and word splitting. This is recommended, but the current usage is correct and there is no need to do all these modifications to be compliant with this rule. For the modifications: - SC2034: ksft_skip appears unused. - SC2046: Quote '$(get_msk_inuse)' to prevent word splitting. - SC2006: Use $(...) notation instead of legacy backticks `...`. Now this script is shellcheck (0.9.0) compliant. We can easily spot new issues.
