When you do 'command > file', you only redirect output sent to 'standard output (stdout)' to the file. Since most errors are sent to 'standard error (stderr)', you need to redirect it as well. If you're using ksh or sh as your shell, executing 'command 2>&1 > file' works well. (The logic here is this: 2>&1 says to redirect file handle 2 (stderr) to file handle 1 (stdout), which is then redirected to file.) This is covered in 'man sh' or 'man ksh'. -- Matthew Emmerton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
