Add parameters to ProcessBuilder - Java

Question

I want to add paramters to the ProcessBuilder. I have a shell script like this "test.sh"

echo "hello"
read user
read pw

I want to call this script "test.sh" with the Process Builder to give the user and the pw as arguments. That the script is automatically doing this. Otherwise I always have to type in the user and the password.. The username and the pw is always the same, that's the reason why I want to do this automatically.

The full path to the script is here {/c/users/lia/desktop/test.sh"..}

So when I execute just the script this in git bash and it is directly here at the desktop with "sh test.sh" I get the content and it works fine..

In my String I have it like this String[] cmd = {"sh test.sh", "user", "pw"};

When I convert it into an jar file (I need it later as a jar file) it does not work. Got the message "cannot find file"

When I do it like this : String [] cmd = {/c/users/lia/desktop/test.sh"..}; it does not work

Thank you all.

How will you execute .sh file which is shell script in windows ? — Sambit, May 17 '19 at 11:57

The shell script reads from the input. You need to change it to use parameters (e.g., $1, $2, etc). — rghome, May 17 '19 at 12:06
"When I convert it into an jar file (I need it later as a jar file) it does not work. Got the message "cannot find file"" You can't run scripts from inside a jar file. You'll need code to extract the script to a temporary directory and run it from there. Also, your users' machines will need to have `sh` available. — Alexey Romanov, May 17 '19 at 12:07
thank you both for your answer. ```echo "hello" echo "user" $1" read "pw: $2" ``` and how do I change the java String cmd ? — Lia, May 17 '19 at 12:09

You can write the shell script like the example given below.

echo "hello"
echo "user $1"
echo "pw: $2"

Now you have to execute as sh test.sh uname1 pwd1. Use this command in Java ProcessBuilder to execute.

@Sambit except your answer does not answer the question, has syntax errors and generally doesn't seem to make any sense. – rghome May 17 '19 at 13:01
@rghome maybe it's ```sh /c/users/Lia/desktop/test.sh ``` maybe it's like this and my code at the top? – Lia May 17 '19 at 19:13
