从数组中接收后挂钩后显示随机消息

Question

我希望它从数组中选择一个项目并显示它，现在它正在显示它们。

以下是我在收到后挂钩结束时所拥有的内容：

# Array with expressions
expressions=("You upload" "Dude what's that smell?" "Some Bytes are Missing!")

# Seed random generator
RANDOM=$$$(date +%s)

# Get random expression...
selectedexpression=${expressions[$RANDOM % ${#expressions[@]} ]}

# Write to Shell
echo $selectedexpression
