size —
display object file segment sizes (text, data and bss)
size displays the text, data and bss segment sizes of
the specified file(s) in bytes (in decimal), and the sum
of the three segments (in decimal and hexadecimal). If a library (archive) is
given, size displays the segment sizes for each object
archive member. If no file is specified
size attempts to report on the file
a.out.
The options are as follows:
-t- At the end of the output print a total of the sizes of all the object
files processed.
-w- Warn about non-object archive members. Normally,
size will silently ignore all archive members
which are not object files.
