Otool - Get file size only

I'm using Otool to look into a compiled library (.a) and I want to see what the file size of each component in the binary is. I see that

otool -l [lib.a]

will show me this information but there is also a LOT of other information I do not need. Is there a way I can just see the file size and not everything else? I can't seem to find it if there is.

Solution

  • The size command does that, e.g.,

    size lib.a

    will show the size of each object stored in the lib.a archive. For example:

    $ size libasprintf.a
   text    data     bss     dec     hex filename
      0       0       0       0       0 lib-asprintf.o (ex libasprintf.a)
    639       8       1     648     288 autosprintf.o (ex libasprintf.a)

    on most systems. OS X format is a little different:

    $ size libl.a
__TEXT  __DATA  __OBJC  others  dec     hex
86      0       0       32      118     76      libl.a(libmain.o)
75      0       0       32      107     6b      libl.a(libyywrap.o)

    Oddly (though "everyone" implements it), I do not see size on the POSIX site. OS X has a manual page for it.
