NAME
readelf - Displays information about ELF files.

SYNOPSIS
readelf [-a--all]
[-h--file-header]
[-l--program-headers--segments]
[-S--section-headers--sections]
[-e--headers]
[-s--syms--symbols]
[-n--notes]
[-r--relocs]
[-u--unwind]
[-d--dynamic]
[-V--version-info]
[-A--arch-specific]
[-D--use-dynamic]
[-x --hex-dump=]
[-w[liaprmfFso]
--debug-dump[=line,=info,=abbrev,=pubnames,=ranges,=macro,=frames,=frames-interp,=str,=loc]
[-I-histogram]
[-v--version]
[-W--wide]
[-H--help]
elffile...

DESCRIPTION
readelf displays information about one or more ELF format
object files. The options control what particular
information to display.

elffile... are the object files to be examined. 32-bit and
64-bit ELF files are supported, as are archives containing
ELF files.

This program performs a similar function to objdump but it
goes into more detail and it exists independently of the BFD
library, so if there is a bug in BFD then readelf will not
be affected.

OPTIONS
The long and short forms of options, shown here as
alternatives, are equivalent. At least one option besides
-v or -H must be given.

-a
--all
Equivalent to specifiying --file-header,
--program-headers, --sections, --symbols, --relocs,
--dynamic, --notes and --version-info.

-h

--file-header
Displays the information contained in the ELF header at
the start of the file.

-l
--program-headers
--segments
Displays the information contained in the file's segment
headers, if it has any.

-S
--sections
--section-headers
Displays the information contained in the file's section
headers, if it has any.

-s
--symbols
--syms
Displays the entries in symbol table section of the
file, if it has one.

-e
--headers
Display all the headers in the file. Equivalent to -h
-l -S.

-n
--notes
Displays the contents of the NOTE segment, if it exists.

-r
--relocs
Displays the contents of the file's relocation section,
if it has one.

-u
--unwind
Displays the contents of the file's unwind section, if
it has one. Only the unwind sections for IA64 ELF files
are currently supported.

-d
--dynamic
Displays the contents of the file's dynamic section, if
it has one.

-V
--version-info
Displays the contents of the version sections in the
file, it they exist.

-A
--arch-specific
Displays architecture-specific information in the file,
if there is any.

-D
--use-dynamic
When displaying symbols, this option makes readelf use
the symbol table in the file's dynamic section, rather
than the one in the symbols section.

-x
--hex-dump=
Displays the contents of the indicated section as a
hexadecimal dump.

-w[liaprmfFso]
--debug-dump[=line,=info,=abbrev,=pubnames,=ranges,=macro,=frames,=frames-interp,=str,=loc]
Displays the contents of the debug sections in the file,
if any are present. If one of the optional letters or
words follows the switch then only data found in those
specific sections will be dumped.

-I
--histogram
Display a histogram of bucket list lengths when
displaying the contents of the symbol tables.

-v
--version
Display the version number of readelf.

-W
--wide
Don't break output lines to fit into 80 columns. By
default readelf breaks section header and segment
listing lines for 64-bit ELF files, so that they fit
into 80 columns. This option causes readelf to print
each section header resp. each segment one a single
line, which is far more readable on terminals wider than
80 columns.

-H
--help
Display the command line options understood by readelf.
