使用ldd看到連接依賴性：

$ ldd /bin/ls 
    linux-vdso.so.1 => (0x00007fff785ff000) 
    libselinux.so.1 => /lib/x86_64-linux-gnu/libselinux.so.1 (0x00007f577a35e000) 
    librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f577a156000) 
    libacl.so.1 => /lib/x86_64-linux-gnu/libacl.so.1 (0x00007f5779f4d000) 
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5779b8e000) 
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f577998a000) 
    /lib64/ld-linux-x86-64.so.2 (0x00007f577a5a1000) 
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f577976c000) 
    libattr.so.1 => /lib/x86_64-linux-gnu/libattr.so.1 (0x00007f5779567000) 
$ ldd /lib/x86_64-linux-gnu/libselinux.so.1 
    linux-vdso.so.1 => (0x00007fff0a2a7000) 
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f72bec97000) 
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f72be8d8000) 
    /lib64/ld-linux-x86-64.so.2 (0x00007f72bf0de000)
