NAME
Read - Read input and parse.
SYNOPSIS
Read Variables/...
DESCRIPTION
Read accepts input from its standard input. It takes as
arguments a list of one or more environment variables into
which it will place the parsed input.
Read chops the input up on whitespace and/or double quotes,
depending on the user's input, placing the first argument in
the first environment variable you supply, the second in the
second and so on. The final environment variable supplied
gets the rest of the input string. If only one variable is
supplied, it gets all the input.
Read may be used to good effect in pipelines (see the Ash
Manual for more information on pipes and several good
examples using Read).
EXAMPLE
Read First Last
S D B
First will contain 'S', while last will contain 'D B'.
Read First Last
"S D B"
First will contain '"S D B"' while last will be empty.
