Sometimes users may want to calculate the MD5 of part of a file(e.g. check
partition contents for debug after flashing, size of which may be greater
than image). This can be done with the "dd" command and pipes, the "md5"
command just needs to support reading from standard input. For example:
`dd if=/dev/virtblk0 bs=512 count=1 | md5`.

usage like:
nsh> sleep 10 &
[5:100]
nsh>set pid1=$!
nsh>sleep 15 &
[6:100]
nsh>set pid2=$!
nsh>wait $pid1 $pid2
'wait' command will block nsh from running until pid1 and pid2 finish.
This is useful for parallel requirements to perform certain tasks

This command looks through the currently running processes and kills
the those that match the selection criteria. This way system can send
signal to processes by name and without knowing the IDs.
Example (kill application hello):
pkill -15 hello
The command can be turned off by NSH_DISABLE_PKILL option and depends
on FS_PROCFS.

Currently new users when try to run NuttX using the SIM
get stuck into simulator, because they have no idea that
poweroff command is used to leave it. Let use KISS approach
and use quit as an alias to poweroff command.
