# ldd32(1)

list dynamic object dependencies

Part of [ldd(1)](/ldd/1.md).

## NAME

**ldd** – list dynamic object dependencies

## SYNOPSIS

**ldd** \[**-a**\] \[**-f** *format* \[**-f** *format*\]\] *program* *...*

## DESCRIPTION

The **ldd** utility displays all shared objects that are needed to run the given program or to load the given shared object. Contrary to [nm(1)](/nm/1.md), the list includes “indirect” dependencies that are the result of needed shared objects which themselves depend on yet other shared objects.

Zero, one or two **-f** options may be given. The argument is a format string passed to [rtld(1)](/rtld/1.md) and allows customization of **ldd**'s output. If one is given, it sets LD\_TRACE\_LOADED\_OBJECTS\_FMT1. If two are given, they set LD\_TRACE\_LOADED\_OBJECTS\_FMT1 and LD\_TRACE\_LOADED\_OBJECTS\_FMT2, respectively. See [rtld(1)](/rtld/1.md) for details, including a list of recognized conversion characters.

The **-a** option displays the list of all objects that are needed by each loaded object.

## IMPLEMENTATION NOTES

**ldd** lists the dependencies of an executable by setting [rtld(1)](/rtld/1.md) environment variables and running the executable in a child process. If the executable is corrupt or invalid, **ldd** may therefore fail without providing any diagnostic error messages.

## EXAMPLES

The following is an example of a shell pipeline which uses the **-f** option. It will print a report of all ELF binaries in the current directory, which link against the old libc.so.6:

```
find . -type f | xargs file -F ' ' | grep 'ELF.*dynamically' | cut -f1 -d' ' | xargs ldd -f '%A %o\n' | grep -F libc.so.6
```
