A continuing problem: While I was running ./ex5, the output is normal. When I was running ./ex5 -help | grep whatever, the output is still normal. However, when I tried ./ex5 -help | head -20, it output the first 20 lines from help, then it output the some error message. I'm curious why there is such an error message. The error message is pasted below.<br>

No, just run the program with the option. For example if there is printed -dm_view_draw <false> then run the program with -dm_view_draw true<br>

I'm testing from my MAC the same commands listed on that page, for example, ex5 -dm_view, nothing interesting happen except the Number of Newton iterations is outputted. I'm expecting that the PETSc numbering would show up as a graphic window or something. Can anyone tell me what's missing here? Thank you! ( Hui )<br>
