read commands from file and run it

[keneid]

Hi!


How can I read a text file with differents commands like ps aux, ls -al, etc. and run it?

I using fileinputstream and runtime.
I just need some help to find some examples to do that.

This work->
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec("c:\\test.exe -id=jallaf -password=jallaf run test");


I want it to be like this:
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec(file-with-command.txt + "-id=jallaf -password=jallaf run test");


hope you understanding my problem.
Thanks

Assuming you are working on unix platform, you need to run it as script(shell or perl). Just put all your commands in a file say "commands.sh".
Assign execute permission using chmod:-
chmod 777 commands.sh

Then, in Java do like this:-

Runtime rt = Runtime.getRuntime();
Process pr = rt.exec(relative-or-complete-path -of-file(commands.sh) + "-id=jallaf -password=jallaf run test");

thank you very much. it's work.

But I have another runtime issue too.

I want the java application read the string into a file.txt and put it in a runtime command.
The issue is: I have a windows application in wine. The text file is for example
cat file.txt
c:\\program files\\shure\\shure.exe

The java application should read this line and put it into here -->
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec(c:\\program files\\shure\\shure.exe "any-command-for-shure");


("any-command-for-shure") is always in the java application - but the string in the text file will change. maybe somebody want to install shure in c:\shure\ so they have to write c:\\shure\\shure.exe in the text file.

I think I should use a FileInputStream and read the file. The string is like String name = "shure";
and i will put the variable in Process pr = rt.exec(shure + "any-command-for-shure"); ??






I hope you understand me this time too.
Thanks.
