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
