My app start tcsh with Runtime.exec("./tcsh").
Up to this point everything works fine.

Then it gets the outputstream of the process.

when i write something like "echo password | sudo -S -u mysql safe_mysqld --user=mysql &" to the output nothing happens.

this is strange because when i write "exit" to the same output tcsh gets terminated like it should.

can anybody help me?

i'm working with mac osx

thanks
