Changing the working directory

[Jörg Eckart]

Hi all,

I want to change the current directory to start commands with
Runtime.exec() at a specified position. Starting the command
with its full path name is not acceptable because of its
arguments. I tried to set the property "user.dir" with
System.get/setProperties(), but this has no effect. I am
working with jdk1.1.8.

Does anybody know how to change the working directory?

Thanks in advance,

Jörg

You can't change the working directory. But try this (quote from Runtime's
Javadoc):

exec(String command, String[] envp, File dir)
Executes the specified string command in a separate process with the
specified environment and working directory.

(You will probably want to use an empty string array for the second
parameter.)

The only best way *is* to use the full path for executing the command, maybe
you can also use the full path for the parameters?
Aside that you could also cd to that path by using a multiple command
statement, which is different for both unix and dos. In does you will do
something like this:
cd mypath & mycommand
the '&' will append two different commands.
