According to the comment in the header of the file, you are not allowed to redistribute that code unless you got permission from the owner. And that's what you are just doing here.

I don't know what do you expect. If you want to change the value, then change it. It's the number in hex format after "VENDOR_KEY1" on the #include line. We don't own that source code, so we can't even start to think what values would have any meaning at all, though.

The question is way too vague and imprecise.

Hi ,

Actually , the format is like this in a file

#define VENDOR_KEY1 0x0
here some data is there
#define VENDOR_KEY2 0x0
here also some data are
#define VENDOR_KEY3 0x0
#define VENDOR_KEY4 0x0
#define VENDOR_KEY5 0x0

So , i want to replace the "0x0" value of "VENDOR_KEY1" to some 0x123456.

My problem is , if i use "sed" , matching pattern as a "0x0" , it is replacing all "VENDOR_KEYS" . But i need to change only the first line.


Pls help me out....

Now it's clearer what you intend to do.

If you have this into a file called a.txt

#define VENDOR_KEY1 0x0
here some data is there
#define VENDOR_KEY2 0x0
here also some data are
#define VENDOR_KEY3 0x0
#define VENDOR_KEY4 0x0
#define VENDOR_KEY5 0x0

This command will do that:

sed -e 's/VENDOR_KEY1 0x0/VENDOR_KEY1 0xffffffff/' a.txt

You can then use redirection to save the new output as another file or whatever.

Or even:

sed '/VENDOR_KEY1 /s/0x0/0xffffffff/' a.txt
