Unix Command - How to see library dependencies of programs? - ldd

Viewing library dependencies of programs in Unix with ldd:

command:

     ldd <path_of_binary>


We would see something like this:


 ldd /bin/grep

        linux-vdso.so.1 =>  (0x00007fffad1ff000)
        libpcre.so.0 => /lib64/libpcre.so.0 (0x00000032fe600000)
        libc.so.6 => /lib64/libc.so.6 (0x00000037eaa00000)
        /lib64/ld-linux-x86-64.so.2 (0x00000037ea600000)




The environment var to load the library is LD_LIBRARY_PATH whether some library was not loaded.
