将参数传递给Shell脚本

Question

I want to execute a shell script using usage() in the script.

I have to give three parameters in the usage block like below:

./script_name server_name path flag

How do I write the code block for this?

Finally, I need to read all the three parameters in a line to execute a jar file.

Answer 1

once you pass parameters you can access them with $1, $2 ... $n and $@ to get everything at once.

./script_name server_name path flag

In the script code

echo $1, $2, $3
echo "$@" #will print the same thing
