I've found this piece of code in the past, it works with bash. Play around with it:
Code:
#!/bin/bash
 
_key()
{
  local kp
  ESC=$'\e'
  _KEY=
  read -d '' -sn1 _KEY
  case $_KEY in
    "$ESC")
        while read -d '' -sn1 -t1 kp
        do
          _KEY=$_KEY$kp
          case $kp in
            [a-zA-NP-Z~]) break;;
          esac
        done
    ;;
  esac
  printf -v "${1:-_KEY}" "%s" "$_KEY"
}
 
_key x
 

case $x in
  $'\e[11~' | $'\e[OP') key=F1 ;;
  $'\e[12~' | $'\e[OQ') key=F2 ;;
  $'\e[13~' | $'\e[OR') key=F3 ;;
  $'\e[14~' | $'\e[OS') key=F4 ;;
  $'\e[15~') key=F5 ;;
  $'\e[16~') key=F6 ;;
  $'\e[17~') key=F7 ;;
  $'\e[18~') key=F8 ;;
  $'\e[19~') key=F9 ;;
  $'\e[20~') key=F10 ;;
  $'\e[21~') key=F11 ;;
  $'\e[22~') key=F12 ;;
  $'\e[A' ) key=UP ;;
  $'\e[B' ) key=DOWN ;;
  $'\e[C' ) key=RIGHT ;;
  $'\e[D' ) key=LEFT ;;
  ?) key=$x ;;
  *) key=??? ;;
esac
 
echo "You have pressed $key"

kstash

KSTASH(8)						    BSD System Manager's Manual 						 KSTASH(8)

NAME

     kstash -- store the KDC master password in a file

SYNOPSIS

     kstash [-e string | --enctype=string] [-k file | --key-file=file] [--convert-file] [--random-key] [--master-key-fd=fd] [--random-key]
	    [-h | --help] [--version]

DESCRIPTION

     kstash reads the Kerberos master key and stores it in a file that will be used by the KDC.

     Supported options:

     -e string, --enctype=string
	     the encryption type to use, defaults to DES3-CBC-SHA1.

     -k file, --key-file=file
	     the name of the master key file.

     --convert-file
	     don't ask for a new master key, just read an old master key file, and write it back in the new keyfile format.

     --random-key
	     generate a random master key.

     --master-key-fd=fd
	     filedescriptor to read passphrase from, if not specified the passphrase will be read from the terminal.

FILES

     /var/heimdal/m-key is the default keyfile if no other keyfile is specified.  The format of a Heimdal master key is the same as a keytab, so
     ktutil list can be used to list the content of the file.
