119 usable as a command prompt, but it is not suitable for any but the
120 most trivial scripting (such as an initrd that calls insmod a few
Eric Andersen88c916b2003-10-22 09:58:56 +0000[diff] [blame]121 times) since it does not understand any Bourne shell grammar. It

123 command editing makes it a very nice lightweight command prompt.
