急需高手帮忙指点下简单脚本调用问题

该脚本如下：
#！/bin/bash
# father script.
echo "this is the father"
FILM="A Few Good Men"
echo "I like the film :$FILM"
# call the child script
# but export variable first
export FILM
child
echo "back to father"
echo "and the film is :$FILM"
调用的“child”脚本如下：
#！/bin/bash
# child
echo "called from father..i am child"
echo "film name is :$FILM"
FILM="Die Hard"
echo "changing film to :$FILM"
|运行father脚本不能调用child脚本，具体问题为”./father:9:child: not found"。
希望能得到高手指点，菜鸟非常感谢。

你调用child脚本时，不应该是

代码:

child

而应该是

代码:

source /path/to/child.sh

第一种用法是用于调用函数的。

安全原因 shell PATH变量中没有./ 所以不会在当前目录查找命令
