-.TH ldd 1 2023-10-31 "Linux man-pages 6.7"
-.SH NAME
-ldd \- print shared object dependencies
-.SH SYNOPSIS
-.nf
-.BR ldd " [\fIoption\fP]... \fIfile\fP..."
-.fi
-.SH DESCRIPTION
-.B ldd
-prints the shared objects (shared libraries) required by each program or
-shared object specified on the command line.
-An example of its use and output
-is the following:
-.P
-.in +4n
-.EX
-$ \fBldd /bin/ls\fP
- linux\-vdso.so.1 (0x00007ffcc3563000)
- libselinux.so.1 => /lib64/libselinux.so.1 (0x00007f87e5459000)
- libcap.so.2 => /lib64/libcap.so.2 (0x00007f87e5254000)
- libc.so.6 => /lib64/libc.so.6 (0x00007f87e4e92000)
- libpcre.so.1 => /lib64/libpcre.so.1 (0x00007f87e4c22000)
- libdl.so.2 => /lib64/libdl.so.2 (0x00007f87e4a1e000)
- /lib64/ld\-linux\-x86\-64.so.2 (0x00005574bf12e000)
- libattr.so.1 => /lib64/libattr.so.1 (0x00007f87e4817000)
- libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f87e45fa000)
-.EE
-.in
-.P
-In the usual case,
-.B ldd
-invokes the standard dynamic linker (see
-.BR ld.so (8))
-with the
-.B LD_TRACE_LOADED_OBJECTS
-environment variable set to 1.
-This causes the dynamic linker to inspect the program's dynamic dependencies,
-and find (according to the rules described in
-.BR ld.so (8))
-and load the objects that satisfy those dependencies.
-For each dependency,
-.B ldd
-displays the location of the matching object
-and the (hexadecimal) address at which it is loaded.
-(The
-.I linux\-vdso
-and
-.I ld\-linux
-shared dependencies are special; see
-.BR vdso (7)
-and
-.BR ld.so (8).)
-.\"
-.SS Security
-Be aware that in some circumstances
-(e.g., where the program specifies an ELF interpreter other than
-.IR ld\-linux.so ),
-.\" The circumstances are where the program has an interpreter
-.\" other than ld-linux.so. In this case, ldd tries to execute the
-.\" program directly with LD_TRACE_LOADED_OBJECTS=1, with the
-.\" result that the program interpreter gets control, and can do
-.\" what it likes, or pass control to the program itself.
-.\" Much more detail at
-.\" http://www.catonmat.net/blog/ldd-arbitrary-code-execution/
-some versions of
-.B ldd
-may attempt to obtain the dependency information
-by attempting to directly execute the program,
-which may lead to the execution of whatever code is defined
-in the program's ELF interpreter,
-and perhaps to execution of the program itself.
-.\" Mainline glibc's ldd allows this possibility (the line
-.\" try_trace "$file"
-.\" in glibc 2.15, for example), but many distro versions of
-.\" ldd seem to remove that code path from the script.
-(Before glibc 2.27,
-.\" glibc commit eedca9772e99c72ab4c3c34e43cc764250aa3e3c
-the upstream
-.B ldd
-implementation did this for example,
-although most distributions provided a modified version that did not.)
-.P
-Thus, you should
-.I never
-employ
-.B ldd
-on an untrusted executable,
-since this may result in the execution of arbitrary code.
-A safer alternative when dealing with untrusted executables is:
-.P
-.in +4n
-.EX
-$ \fBobjdump \-p /path/to/program | grep NEEDED\fP
-.EE
-.in
-.P
-Note, however, that this alternative shows only the direct dependencies
-of the executable, while
-.B ldd
-shows the entire dependency tree of the executable.
-.SH OPTIONS
-.TP
-.B \-\-version
-Print the version number of
-.BR ldd .

-.TQ
-.B \-d
-Perform relocations and report any missing objects (ELF only).
-.TP
-.B \-\-function\-relocs
-.TQ
-.B \-r

-report any missing objects or functions (ELF only).
-.TP
-.B \-\-help
-Usage information.
-.\" .SH NOTES
-.\" The standard version of
-.\" .B ldd
-.\" comes with glibc2.
-.\" Libc5 came with an older version, still present
-.\" on some systems.
-.\" The long options are not supported by the libc5 version.
-.\" On the other hand, the glibc2 version does not support
-.\" .B \-V
-.\" and only has the equivalent
-.\" .BR \-\-version .
-.\" .P
-.\" The libc5 version of this program will use the name of a library given
-.\" on the command line as-is when it contains a \[aq]/\[aq]; otherwise it
-.\" searches for the library in the standard locations.
-.\" To run it
-.\" on a shared library in the current directory, prefix the name with "./".
-.SH BUGS
-.B ldd
-does not work on a.out shared libraries.
-.P
-.B ldd
-does not work with some extremely old a.out programs which were
-built before
-.B ldd
-support was added to the compiler releases.
-If you use
-.B ldd
-on one of these programs, the program will attempt to run with
-.I argc
-= 0 and the results will be unpredictable.
