[2004-03-31] Understanding Floating Point Formats
Under ordinary circumstances, you don't have to know or care how numbers are represented within your programs. However, when you are transferring data files that contain numbers, you will have to convert if the storage formats are not identical. If the numbers are just integers, that's fairly easy because the only differences will be the length and the byte order: how many bytes the number takes up, and whether it is stored lsb or msb (least signifacant byte or most significant byte first). Once you know that, conversion is trivial.
[2004-03-03] Getopt and Getopts
Both "getopt" and getopts are tools to use for processing and validating shell script arguments. They are similar, but not identical. More confusingly, functionality may vary from place to place, so you need to read the man pages carefully if your usage is more than casual.
