Linux FAQs with Answers--How to check what libraries are used by a program or process on Linux
|
|
================================================================================
|
|
> **Question**: I would like to know which shared libraries are loaded at run-time when I invoke a particular executable. Is there any way to identify shared library dependencies of a program executable or a running process on Linux?
|

### Check shared library dependencies of a program executable ###
|
|
|
|
To find out what libraries a particular executable depends on, you can use ldd command. This command invokes dynamic linker to find out library dependencies of an executable.
|
|
|
|
$ ldd /path/to/program
|
|
|
|
|
|
|
|
Note that it is NOT recommended to run ldd with any untrusted third-party executable because some versions of ldd may directly invoke the executable to identify its library dependencies, which can be security risk.
|
|
|
|
Instead, a safer way to show library dependencies of an unknown application binary is to use the following command.
|
|
|
|
$ objdump -p /path/to/program | grep NEEDED
|
|
|
|
|
|
|
|
Check shared library dependencies of a running process
|
|
|
|
If you want to find out what shared libraries are loaded by a running process, you can use pldd command, which shows all shared objects loaded into a process at run-time.
|
|
|
|
$ sudo pldd <PID>
|
|
|
|
Note that you need root privilege to run pldd command.
|
|
|
|
|
|
|
|
Alternatively, a command line utility called pmap, which reports memory map of a process, can also show shared library dependencies of a running process.
|
|
|
|
$ sudo pmap <PID>
|
|
|
|
|
|
