android - How to get the content of /dev/logo in shell?

Question

I can read the content of /dev/logo in C,

fd = open("/dev/logo", O_RDONLY);

len = read(fd, logo_addr, 512);

Now I want to do these things using shell command, how to do?

Can I use

$ adb shell cat dev/logo >logo.dev

?

Answer 1

你能用dd吗？就像是：

dd /dev/logo bs=1 count=512 of=logo.dev

假设您需要读取设备的 512 字节。
