mckarl · Apr 20, 2000

ok, check dis owt.. #!/bin/ksh # # Boring nicey nicey stuff # clear echo "Welcome to karls ^[[5m MAD ^[[0m party" echo "please enter your name: \c" read user_name echo "Well, $user_name hope you have fun!" sleep 4 # # main menu # clear echo "\t\t1. ak47 demolishion       2. have a sandwich\n" echo "\t\t3. talk to pretty girl    3. get blind drunk\n" echo "\t\t                       :\c" read what_to_do # # conditions # case what_to_do in # # and the program goes on. # #################~~~~~~~~~~~~~~~~~############ what I want to do, is allow the user to input a letter, and it doesnt need a return-code. C what i mean? another thing is, being able to DRAW with a shell script, so i could put a pretty box or something around. know what i mean? like - screen 1: +++++++++++++++++++++ + input here: [ ]   + # where the input goes +++++++++++++++++++++ can anyone help with the above? 1. to accept characters without the need for a return code 2. draw screen, then again over the top of it, or prompting some type of character location? This would be most useful in a korn shell environment, i know it's possible in a C shell env. so if you could help with either, i would be most greatful!!!!! Thanks for any help!! ... karl!

Karl - You can 'draw' a screen using a clear command and some print or echo/print commands like so: clear print "************************************************" print "**            Hello "$LOGNAME"                  **" print "** Please select 1 to do something            **" print "** Please select 2 to do something else       **" print "************************************************" The menu can be done with a 'select' statement, Your PS3 prompt and a do loop like so: PS3='Enter Choice? ' select choice in 'Something' 'Something else' do   case $REPLY in      1 ) something_func ;;      2 ) somethingelse_func ;;      x ) break ;;      * ) print "Invalid choice. Please try again." ;;   esac done The select statement builds a menu for you, the REPLY holds the user's answer.  If '1' is pressed the something_func is preformed, if '2' is pressed the somethingelse_func is performed, 'x' will terminate the script (as well as <cntl> d), If anything else is entered, the wild card '*' will pick it up and display the "Invalid choice" message.  The PS3 prompt is used by the select statement to prompt the user.   I hope I haved answered your question!

You might like to consider using the dialog command. McH

If you'd like "hot-key" behavior, where the input key is not echoed and the user doesn't need to hit Enter, try the following: stty raw -echo key=$(dd if=$(tty) ibs=1 count=1 2>/dev/null) stty -raw echo Rod Knowlton <a href=mailto:jrknowlton@visto.com>jrknowlton@visto.com</a> <a href= > </a>
