we are novice unix users running a hewlett-packard 9000/835 under hp-ux (a berkeley and at &tt unix hybrid. how do we activate a keyboard beep from within a korn shell script? the idea is to warn users of invalid entries before the screen clears. your assistance is appreciated. thanx, lee ratzan univ of medicine and dentistry of nj .

The standard way to beep is to echo a Control-G character (^G).

This will work in most cases. The more general solution is to use the "tput" command and the terminfo database (see man pages for "tput (1)" and "terminfo (4)"). The use of tput allows the user to be on a wide array of terminal types and still have the desired response by his/her terminal. For the "beep" use the following mthod in your Korn shell: beep=`tput bel` print "${beep}" Similar capabilities can be defined for text attributes (i.e. bold, normal), cursor movement (i.e. home cursor, cursor down, cursor up), clear to end of line or clear to end of screen, and so forth.

Others will suggest echoing a control-G. Which works on most terminals. Most versions of UNIX (at least, ATT'ish ones) have a generic interface to terminals called terminfo, in which each type of terminal is described so that various applications can figger out how to control the terminal. With terminfo, there is a command called "tput". A slightly more generic solution to getting a beep would be to call: tput bel Which consults the database and emits the sequence required to get a bell. Tho, in some cases, people have redefined it to do other "obvious" things. (eg: inverse flash the screen - eugh ;-) You can use tput to emit other things too without having to know the interface to the terminal. -- Chris Lewis, Phone: (613) 832-0541, Domain: clewis@ferret.ocunix.on.ca UUCP: ...!cunews!latour!ecicrl!clewis; Ferret Mailing List: ferret-request@eci386; Psroff (not Adobe Transcript) enquiries: psroff-request@eci386 or Canada 416-832-0541.
