executing UNIX passwd command through Java

[Alex Kravets]

Hi,
Is there a way to execute UNIX's passwd command through Java? When I execute this command is UNIX shell it's interactive, so I don't see a way of simulating <enter> key through Java code. Is there another way?
thanks,
Alex

instead u can make a C EXE and run that from java prog...
use Process class for that and Process.exe() for that...
i've nt done this but i believe its possible in C.

Right, I know it's possible to use C module for this, but I wanted to know if it was possible to do the same thing straight from java.

this should work
echo <password> | passwd <username>

where
<password> = your desired password
<username> = your username

You can easely execute that with
Runtime.getRuntime().exec("echo <password> | passwd <username>");
