shell 中调用其他的脚本

方法有三种：

1 使用source

2 使用 .

3 使用sh

简单实验：

first.sh

#!/bin/bash
echo 'your are in first file'

second.sh

#!/bin/bash
echo 'your are in second file'

source first.sh // . first.sh // sh first.sh

执行结果：

your are in second file
your are in first file

现在讨论关于参数传递：

first.sh

#!/bin/bash
echo 'your are in first file'
echo "${0} ${1}"

second.sh

#!/bin/bash
echo 'your are in second file'
echo "${0} ${1}"

. first.sh ${2} //source first.sh

执行：./second.sh abc 123

your are in second file
./second.sh abc
your are in first file
./second.sh 123

改变second.sh

second.sh

#!/bin/bash
echo 'your are in second file'
echo "${0} ${1}"

sh first.sh ${2}

执行：

./second.sh abc 123

结果：

your are in second file
./second.sh abc
your are in first file
first.sh 123

所以在调用的那个脚本需要传递参数的时候还是要注意选对方法的
