When rm -r is passed with no address specified, it will automatically recursively unlink all files under the root path ('/') until unlinking to the mounted folder causes the unlink to fail. In this change, rm -r without a specified path will prompt for missing arguments
Current implementation is broken, in this patch ECHO is
disabled by termios.
This patch works with https://github.com/apache/nuttx/pull/8950

The logic that handles back-quotes was faulty, i.e. example command
set FOO `ls -l` would be split into two tokens as follows:
- set FOO `ls
- -l`
This results in nsh: `: no matching ` error, this fixes that issue.
This adds support for more complex alias handling, such as:
$ alias ls='ls -l'
Previously such an alias was not split into the command verb and the
argument correctly, instead the full alias string was handled as the
verb, which obviously fails.
This commit fixes this by expanding the alias, checking whether it has
arguments and if so, it merges the expanded alias + the old command line
together, resulting in a completely new command line.
Example (assuming the alias above has been created):
$ ls /bin
Results in a new command line: "ls -l /bin" which is then parsed and
executed.
switchboot <image path>
Switch to the updated or specified boot system. This command depends on
hardware support CONFIG_BOARDCTL_SWITCH_BOOT. `<image path>` point to a
partion or file which contain the firmware to boot.

boot [<image path> [<header size>]]
Boot a new firmware image. This command depends on hardware support
CONFIG_BOARDCTL_BOOT_IMAGE. <image path> may point to a partion or file
which contain the firmware to boot. The optional, numeric argument
<header size> may be useful for skipping metadata information preprended
to the firmware image.

A resulting word that is identified to be the command name word of a
simple command shall be examined to determine whether it is an unquoted,
valid alias name.
The keyword here being "a simple command", arguments are not subject to
expansion.
This adds support for string aliases into nsh. There are some nuances that
are not handled correctly yet:
- Reserved words can be overloaded, which is a clear POSIX violation
The parser is modified to detect, handle and remove quotes from the
command string. Whatever is inside the quotes is treated as a string
literal. If no matching end quote is found, the terminal prints out
and error.
If the code only change c_oflag, c_iflag and c_lflag, not c_cflag in termios.

From comment in cmd_ifconfig, it seems that we support `ifconfig [interface]`, but actually not considering the interface param now. After this commit, we only print the information of interface specified in param, just like linux.
