  • linux shell中自定义函数简单例子

    1、

    root@PC1:/home/test# ls
    test.sh
    root@PC1:/home/test# cat test.sh
    #!/bin/bash
    #using a function in a script
    
    function func1 {                                     ## shell自定义函数的格式之一是 function + 函数名 {command}
            echo "this is an example of a function"
            }
    
    for ((i = 1; i <= 5; i++))
    do
    func1                                  ## 利用for循环连续调用函数5次
    done                     ## 定义函数的目的是实现代码的复用,避免重复写command
    root@PC1:/home/test# ls
    test.sh
    root@PC1:/home/test# cat test.sh
    #!/bin/bash
    #using a function in a script
    
    function func1 {
            echo "this is an example of a function"
            }
    
    for ((i = 1; i <= 5; i++))
    do
    func1
    done
    root@PC1:/home/test# bash test.sh   ## 执行效果
    this is an example of a function
    this is an example of a function
    this is an example of a function
    this is an example of a function
    this is an example of a function
