How to list files inside a .a file

Question

How can I get to know what files are part of my .a file? Which command should I use?

Answer 1

I think it would be simpler to use ar for what it's meant (manipulating archives)

ar t foo.a

From man page:

-t List the specified files in the order in which they appear in the archive, each on a separate line. If no files are specified, all files in the archive are listed.

man 1 ar for more info.
