Shell脚本弹奏中文版“生日快乐歌”
在《Shell命令控制蜂鸣器发声》一文中,我们了解到了如何在Ubuntu下安装beep命令来控制PC主板上蜂鸣器发声,这次我们想让蜂鸣器弹奏出中文版的“生日快乐歌”,首先还是要用sudo modprobe pcspkr命令加载驱动,然后在Shell脚本所在目录下执行bash -e beep_birthday_song.sh命令,这样就可以执行我们写的脚本弹奏了,我们的脚本名字为beep_birthday_song.sh,内容如下:
#!/bin/sh freq=(392 392 440 392 523 494 392 392 440 392 587 523 392 392 784 659 523 494 440 698 698 659 523 587 523) delay=(375 125 500 500 500 1000 375 125 500 500 500 1000 375 125 500 500 500 500 1000 375 125 500 500 500 1000) i=0 len=${#freq[*]} while [ $i -lt $len ] do beep -f ${freq[$i]} -l ${delay[$i]} let ++i done
