Introduction<\/h2>\n

ldd is the useful command to see executable files and shared object dependencies. Files that start with \/lib are called libraries. A library helps a program to use common processes without any handling or administration overhead.<\/p>\n

There are two types of libraries: static and dynamic libraries.<\/p>\n

Below is the guide on how to use the ldd command in Linux as we go through below.<\/p>\n

Install the ldd command<\/h2>\n

If your ubuntu version is too old, let\u2019s run apt command to install:<\/p>\n

$ sudo apt install libc-bin<\/pre>\n
Output:<\/p>\n
<\/p>\n
The syntax of ldd command<\/h2>\n
$ ldd [option]... file...<\/pre>\n
[option]<\/strong><\/p>\n
-v <\/strong> show all information<\/p>\n
-u <\/strong> show unused direct dependencies<\/p>\n
-d <\/strong> data relocation<\/p>\n
-r <\/strong> data and function relocation<\/p>\n
Show detailed information<\/h2>\n
You can use the ldd command with option -v<\/strong> to show detailed information. For example, we will display detailed the dependencies of the ls command:<\/p>\n
$ ldd -v \/bin\/ls<\/pre>\n
Output:<\/p>\n
<\/p>\n
Show unused direct dependencies<\/h2>\n
You can use the ldd command with option -u<\/strong> to show unused direct dependencies. For example:<\/p>\n
$ ldd -u \/bin\/grep<\/pre>\n
Output:<\/p>\n
<\/p>\n
