Hi ,

can anyone tell me how to write java application which will execute linux-commands from java application (i.e, without opening command window manually)..
My Question: Is it possible to execute Linux-commands from java application.

Normally we open command window manually and execute commands in command window...Here i want to make my java program to execute command and retrieve resultant data ..Is it possible to execute linux-commands from java application?
If anyone know answer please assist me.

Giving up is the easiest thing in the world to do..but holding it together when everything seems like falling apart is true strength!!
with regards, Harish.T

Here's a good article that covers reading the stdout and errout streams, an essential part for some commands.

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

Hello,

have a look at Runtime.exec() and process() commands.

One Hint: Always clear the input and output streams of these two methods to avoid hands in execution.
