如何在bash中退出函數

Question

如果在不殺死整個腳本的情況下條件爲真，那麼如何退出函數，只需返回到調用函數之前。

例

Answer 1

使用return操作者：

function FUNCT { 
    if [ blah is false ]; then 
    return 1 # or return 0, or even you can omit the argument. 
    else 
    keep running the function 
    fi 
} 

Answer 2

使用：

return [n] 

從help return

回報：迴歸[N]

Return from a shell function. 

Causes a function or sourced script to exit with the return value 
specified by N. If N is omitted, the return status is that of the 
last command executed within the function or script. 

Exit Status: 
Returns N, or failure if the shell is not executing a function or script.
