size [-A|-B|-G|--format=compatibility] [--help] [-d|-o|-x|--radix=number] [--common] [-t|--totals] [--target=bfdname] [-V|--version] [objfile...]
The GNU size utility lists the section sizes---and the total size---for
each of the object or archive files objfile in its argument list. By
default, one line of output is generated for each object file or each
module in an archive.
objfile... are the object files to be examined. If none are specified,
the file "a.out" will be used.
