Deleting a file object from a library

Question

I've created a library with 3 file objects using:

ar rv arhiva.a file.o file2.o file3.o

Why I can't delete a file object from it? I've used

ar xv arhiva.a file.o

Answer 1

from ar(1) man page

   d   Delete modules from the archive.  Specify the names of modules to be
       deleted as member...; the archive is untouched if you specify no files to
       delete.

       If you specify the v modifier, ar lists each module as it is deleted.

have you tried .. ?

 ar dv arhiva.a file.o

• x stand for eXtract
• you can copy/paste line, just make four white to have indentation ..
