txt > /users/test/file3.txt").exec;
It reports an error like this:
cat: /users/test/file3.txt: No such file or directory
it seems it is the redirecting ">" symbol makes problem.
can anyone help here?! thanks. |

then use java to call that script.

generally requires writing a thread to read the output

发帖数: 61 | 5 Thanks! yes, that is one solution. another one is here, need to write the
command as a string array and tell the shell dir clearly:
http://www.unix.com.ua/orelly/java-ent/servlet/ch13_04.htm
"
String[] command = { "/bin/csh", "-c", "finger | grep -v jhunter" };
The program Java executes is /bin/csh. csh is passed two arguments: -c,
which asks the shell to execute the next parameter, and finger | grep -v
jhunter, which is executed by the shell."
