sounding system bell in a shell script run from toolbar icon
hey all - here's my question: I use IceWm which i love. You can write shell scripts and initiate them via icons on the menu or toolbar... i wrote one to mount and unmount my CD-Rom. Part of this script is to echo a system bell when the Drive is fully mounted/unmounted or a longer bell if the device is busy etc... It works great when executed from a terminal window or xterm in X. But when i execute it via the menu/toolbar icon it won't sound the system bell ( i assume it has something to do with echo ) ... so far the way i have found around this is to tell the icon to open an xterm window #cut from $HOME/.icewm/menu #the first word prog means program ; CD is the title displayed ; #mounter is the name internal to Icewm and the rest is what is executed prog CD mounter xterm +ls -geom 5x3-0+0 -T '' -bg red -fg red -e /home/slamson/bin/mounter #prog CD mounter mounter #end of cut the uncommented one opens the xterm and it functions fine - opening a small xterm and echoing a bell... the commented one works great too, but no system bell. How can i get the system bell to sound - you'll note i also use xset b to set duration etc at the bottom of the script - without opening a window to run this simple script?

But let me know if there is a better way that you know of. Have a look for the command beep, it allows you to make all sorts of beeps using the command line. If thats not an option it may be possible to echo ^G to /dev/console which I have found makes a beep everytime, no matter how it is running. One thing I have found however with sending ^G's is that there needs to be a delay if you want more than 1 beep otherwise it just buffers the beep into 1.. if your after more then give the beep command a try.
