Verify use (or export if used externally). ^--^ SC2034: _pct appears unused. Verify use (or export if used externally). This variable is intentionally unused since it is needed to parse through the output. commit used "_" as a prefix for this throw away variable. But this stil shows warning with shellcheck v0.6. Fix this by only using "_" instead of prefix and variable name.
