1.编写shell脚本内容: bsh1.sh文件
#!/bin/bash
echo "hello,ljf"
echo "what is your name?"
read p
echo "my name is ${p}"
2.执行脚本
chmod +x ./bsh1.sh
sh ./bsh1.sh
或者 ./bsh1.sh
3.执行结果：
[jurf@ljf-centos ljfshell1113]$ ./bsh1.sh
hello,ljf
what is your name?
l
my name is l
[jurf@ljf-centos ljfshell1113]$ sh ./bsh1.sh
hello,ljf
what is your name?
fu
my name is fu
“#!” 是一个约定的标记，它告诉系统这个脚本需要什么解释器来执行。
read命令是从 stdin 获取输入并赋值给 P 变量，最后在 stdout 上输出。
