Specifically, could someone explain what the flags used with the commands are? In the pset4 specs at one point it is mentioned that they use a different value for -c depending upon the number of columns you want to output. I don't understand the values being used with the flags. I am trying to see the hex dump of my images for the resize problem and am having trouble viewing it. Thought maybe I am not using xxd the way its supposed to be used
xxd's manual page,
-c <cols> formats
<cols> bytes per line. For example,
-c 12 formats 12 bytes per line.
-g <bytes> groups each
<bytes> bytes of the
<cols> bytes per each line together. For example,
-g 3 groups each 3 bytes of the 12 bytes, in a line, together.
-s <seek> starts at byte number
<seek> from the beginning of the file. For example,
-s 54 starts at byte 54 from the beginning of the file.
