如何从单个测试中执行两个 BASH shell 命令？

Question

Why does this not work?

test $? -eq 1 || $(echo "hello"; echo "hi")

I get the following error:

Command 'hello' not found, but can be installed with:
snap install hello              # version 2.10, or
apt  install hello              # version 2.10-2ubuntu4
apt  install hello-traditional  # version 2.10-5
See 'snap info hello' for additional versions.

You're looking for 3.2.5.3 Grouping Commands

test $? -eq 1 || { echo "hello"; echo "hi"; }

The spaces around the braces and the trailing semicolon (or newline) are required.

However, don't test the exit status with the $? variable (it's too easy to accidentally insert another command in there)

Use the command directly

some command here && { echo hello; echo hi; }
