NAME
getkey - extracts values from keyword=value string
SYNOPSIS
getkey [quiet] keyword
DESCRIPTION
getkey reads stdin for a pair key=value and prints out
value to stdout and exits with error code 0. If key is not
found it prints the message: getkey: keyword key not found and exit
with error code
1.
If the quiet option is specified the program does not print an error
message if the keyword is not found, but still exits with a code of
1.
If multiple lines are fed into getkey they are processed to stdout with
intervening newlines on
output.
EXAMPLE
echo done move_sec mils=25.4 | getkey mils produces the output `25.4'.
