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.

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 Barry > > From: Matthew Knepley [[email protected]] > Sent: Wednesday, May 28, 2014 12:10 PM > To: Sun, Hui > Cc: Barry Smith; [email protected] > Subject: Re: [petsc-users] Question about dm_view > > On Wed, May 28, 2014 at 1:28 PM, Sun, Hui <[email protected]> wrote: > Thanks Barry for quick reply.
