objfile...
objdump displays information about one or more object files. The options control what particular
information to display. This information is mostly useful to programmers who are working on the
compilation tools, as opposed to programmers who just want their program to compile and work.
objfile. . . are the object files to be examined. When you specify archives, objdump shows infor-
mation on each of the member object files.
The long and short forms of options, shown here as alternatives, are equivalent. At least one option
from the list -a,-d,-D,-e,-f,-g,-G,-h,-H,-p,-r,-R,-s,-S,-t,-T,-V,-x must be given.
-a
-archive-header
If any of the objfile files are archives, display the archive header information (in a format
similar to ls -l). Besides the information you could list with ar tv, objdump -a shows the
object file format of each archive member.
