bin/dledger/fast-try.sh: 23: bin/dledger/fast-try.sh: Syntax error: "(" unexpected

• Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.

• Write necessary unit-test(over 80% coverage) to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add integration-test in test module.
• Run mvn -B clean apache-rat:check findbugs:findbugs checkstyle:checkstyle to make sure basic checks pass. Run mvn clean install -DskipITs to make sure unit-test pass. Run mvn clean test-compile failsafe:integration-test to make sure integration-test pass.

@mymailmjj Thanks for submitting. You are right. However, the most important reason is that the default sh for Ubuntu/Debian is dash (the Debian Almquist Shell) rather than bash (the GNU Bourne-Again Shell), and dash does not support some syntax.
