vmstat 1 1|sed 1,2d|awk '{printf("%s\n",$1)}'|read var
echo $var
This syntax run on AIX (ksh) but not on linux (bash).

vmstat 1 1|sed 1,2d|awk '{printf("%s\n",$1)}'

Trying to use the read command. How do you add a 2nd option? In this example I'd like to offer two options, pre and post. If you answer pre, you get one output but if you answer post, you get another output.
echo Is this pre or post?
read pre
if
then echo You have typed pre.

gtty
STTY(3) BSD Library Functions Manual STTY(3)NAME
stty, gtty -- set and get terminal state (defunct)
LIBRARY
Compatibility Library (libcompat, -lcompat)
SYNOPSIS
#include <sgtty.h>
stty(int fd, struct sgttyb *buf);
gtty(int fd, struct sgttyb *buf);
DESCRIPTION
These interfaces are obsoleted by ioctl(2). They are available from the compatibility library, libcompat.
The stty() function sets the state of the terminal associated with fd. The gtty() function retrieves the state of the terminal associated
with fd. To set the state of a terminal the call must have write permission.
The stty() call is actually 'ioctl(fd, TIOCSETP, buf)', while the gtty() call is 'ioctl(fd, TIOCGETP, buf)'. See ioctl(2) and tty(4) for an
explanation.
DIAGNOSTICS
If the call is successful 0 is returned, otherwise -1 is returned and the global variable errno contains the reason for the failure.
SEE ALSO ioctl(2), tty(4)HISTORY
The stty() and gtty() functions appeared in 4.2BSD.
