Problematic code:

if true
then
  echo "True"
done

Preferred code:

if true
then
  echo "True"
fi

Detected an if statement that does not appear to have a matching terminating fi. This could be because it's missing entirely, or because the if statement was incorrectly terminated by a mismatched done, esac, ) or something similar. A companion warning SH-1047 is emitted at the point where ShellCheck expected the fi.

Check that the if statement is completely and correctly terminated.
