runtime exec

Is it possible to run a command line type instruction from within Java, even if the command line isn't a program like word.exe ( I am trying to run a mysqldump command to copy a database from one linux box to another ).
...Is it possible to call a shell script using runtime exec? or is there a better way

Shell scripts are interpretted by a program such as bash. You could call bash with an argument of the shell script.

Peter it depends what you need to do !
For a pure dump, just do as said :
exec(new String(){"/bin/bash", "/home/me/"})
this will be the fastest.
Otherwise you may have a JDBC connection from DB to DB, also !
