Hello,
In my attempts to write a simple script that lets the user select
options with a single key stroke I found no other way than to use bash
and its built-in read command with -n 1.
I am looking for a way to do this in ksh(1). Any ideas? Please...
Some snippets from the bash(1) man page:
read [-ers] [-a aname] [-d delim] [-i text] [-n nchars] [-N nchars] [-p
prompt] [-t timeout] [-u fd] [name ...]
One line is read from the standard input, or from the file [...]
-n nchars
read returns after reading nchars characters rather than
waiting for a complete line of input, but honor a
delimiter if fewer than nchars characters are read
before the delimiter.
Thanks in advance, Marcus
