Shell Script Pass Parameter

What does it mean in the shell that we will see the symbols of $ , $, and $? Simply put is the name of the shell script that you wrote, the first parameter you wrote to your shell script, and the second parameter that you wrote for your shell script.

For example, you create a new shell script test.sh, which reads as follows:

#!/bin/shecho "shell脚本本身的名字: $0"echo "传给shell的第一个参数: $1"echo "传给shell的第二个参数: $2"

After saving the exit, you enter in the directory where the test.sh is locatedbash Test.sh 1 2

The result is:

The name of the shell script itself: test.sh The first parameter passed to the shell: 1 The second parameter passed to the shell:  2
