I'm trying to do some tricks with dd. I thought it would be possible to store some hexvalues in a variable called "header" to pipe it into dd.
My first step without a variable was this:
$ echo -ne "\x36\xc9\xda\x00\xb4" |dd of=hex $ hd hex 00000000 36 c9 da 00 b4 |6....| 00000005
After that I tried this:
$ header=$(echo -ne "\x36\xc9\xda\x00\xb4") $ echo -n $header | hd 00000000 36 c9 da b4 |6...| 00000004
As you can see I lost my
\x00 value in the
Does anyone have an explanation for this behavior? This is driving me crazy.
