This problem involves writing a Bash script that defines a function named "divide()" to calculate and return the division of two given numbers. The function should take two arguments, divide the first number by
Although bash has a return statement, the only thing you can specify with it is the function's status, which is a numeric value like the value specified in anexitstatement.The status value is stored in the $? variable. If a function does not contain a return statement, its status is se...

export -f function_name 5.2、函数参数和返回值 (1)内建 local 函数: local 创建的变量只在函数内部使用,退出函数变量即实效。 (2)参数: 通过位置参量可以向函数传递参数,该参数不会影响函数外使用的任何位置参量。 (3)内建 return 函数: return 用来退出函数并返回到调用函数的地方。如果没有给 return 指定...

For example, a bash function return value is limited to number values between 0 and 255, nor can you safely use indirection in bash. This example will implement a rand function and a shuffle function. Both functions use local and global variables to pass values around. If you need to ...
