'sudo -S' should help here: it'll output the sudo password prompt on stderr so that Eshell can see it and handle password entry. (You should be able to enter your password anyway, but without the -S it would just be echoed to the screen.) But that's not the most interesting part. I can execute the > command with 'eshell/sudo'.

I can't reproduce this particular issue, but I can reproduce *an* issue. It seems to be due to "head -10" exiting early (as it should), which results in a broken pipe. However, Eshell's broken pipe handling wasn't properly cleaning up the process ("grep" in this example).
