Hi.

Some possibilities:
Code:
Read one and only one character

        1) bash & ksh: read -n1

        2) zsh: read -k 1

        3) 56 examples in various codes at:
           https://rosettacode.org/wiki/Keyboard_input/Obtain_a_Y_or_N_response
           ( Item 54 for shell, Verified 2016.06.20 )

        4) With dd and stty, encapsulated in a function:
                getchar()
                {
                  local oldstty char
                  oldstty=$(stty -g)
                  stty cbreak -echo
                  char=$( dd bs=1 count=1 2>/dev/null )
                  stty $oldstty
                  echo "$char"
                }
            ...
            char=$( getchar )

        5) qprompt, timer, specific characters, prompt-string, etc.; in c
           http://www.ibiblio.org/pub/historic-linux/ftp-archives/sunsite.unc.edu/Nov-06-1994/utils/shell/qprompt-2.3.tar.gz
           ( Verified 2016.06.20, compiles with warning, worked in 64-bit )

Best wishes ... cheers, drl

Edit 1: added link to old qprompt code.

NAME
sim, SIM - Software phrase input method DESCRIPTION
The phrase input method is an input method that is commonly used in a Chinese environment. The software phrase input method (SIM) is a a mechanism supported by the Asian tty driver, atty and the simd daemon through the utx facility (see atty(7), simd(8), and utx(7)). The stty command activates the software phrase input method, while the phrase utility creates and manages the phrase database (see stty(1) and phrase(1)). Changes to the phrase database may not be reflected in SIM sessions that were started before the changes were made. Therefore, users have to stop and then restart SIM sessions using the stty command to have access to the changed phrase database. SEE ALSO
Commands: phrase(1), stty(1), simd(8), utxd(8) Files: atty(7), utx(7) sim(5)
