linux 檢視庫資訊
strings : 列出檔案中的所有可列印字串
strip : 從目標檔案中刪除符號表資訊
nm : 列出目標檔案中符號表中定義的符號
size : 列出目標檔案中節的名字和大小
ldd
列出可執行檔案和動態庫所依賴的動態庫資訊。
DESCRIPTION
ldd prints the shared libraries required by each program or shared library specified on the command line.
readelf
列出ELF格式檔案的資訊。readelf 後面必須跟引數，引數控制要顯示的內容。readelf功能與objdump相似，且其不依賴BFD庫。
readelf displays information about one or more ELF format object files. The options control what particular information to display.
elffile... are the object files to be examined. 32-bit and 64-bit ELF files are supported, as are archives containing ELF files.
This program performs a similar function to objdump but it goes into more detail and it exists independently of the BFD library, so
if there is a bug in BFD then readelf will not be affected.

objdump 與readelf功能相似。objdump : 所有二進位制工具之母。能夠顯示一個目標檔案中的所有資訊，它最有用的功能是反彙編.text節中的二進位制指令
DESCRIPTION
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 information on each of the member object
files.
