printing a string

Dear all:

I am trying to print a string in a file using the following:

fprintf(input, "EXTN=`date +\"\%A_H_M_S\"`\n");

and getting the following :

EXTN=`date +"0X0.0000000000001P-1022_H_M_S"`

Why am I getting this? and how can I have "%A" in my string?

Regards,

wei

If you want to print a literal percent sign, you need to use %% (just as you need to use \\ to get a literal backslash).

%A means "print a floating point number in hexadecimal scientific notation format".
