Unless you're keen to know the name of the file you're reading for, there's no real difference in this case.

As for "POSIX", when asked what OS you are using, it's neither here nor there.
I was told that it's POSIX, similar to the Korn shell. That you could use:

#!/usr/bin/sh
or
#!/usr/bin/ksh


in the shell scripts but they seem to work differenly so I'm sticking to /sh

SIZE(1) 						      General Commands Manual							   SIZE(1)

NAME
size - print the size of the sections in an object file SYNOPSIS
size [ option ... ] [ object ... ] DESCRIPTION
Size (without the -m option) prints the (decimal) number of bytes required by the __TEXT, __DATA and __OBJC segments. All other segments are totaled and that size is listed in the `others' column. The final two columns is the sum in decimal and hexadecimal. If no file is specified, a.out is used. The options to size(1) are: - Treat the remaining arguments as name of object files not options to size(1). -m Print the sizes of the Mach-O segments and sections as well as the total sizes of the sections in each segment and the total size of the segments in the file. -l When used with the -m option, also print the addresses and offsets of the sections and segments. -x When used with the -m option, print the values in hexadecimal (with leading 0x's) rather than decimal. -arch arch_type Specifies the architecture, arch_type, of the file for size(1) to operate on when the file is a fat file. (See arch(3) for the cur- rently know arch_types.) The arch_type can be "all" to operate on all architectures in the file. The default is to display only the host architecture, if the file contains it; otherwise, all architectures in the file are shown. SEE ALSO
otool(1) BUGS
The size of common symbols can't be reflected in any of the numbers for relocatable object files. Apple Computer, Inc. May 23, 2002 SIZE(1)
