ELFFILE...
'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.
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 specifying '--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.
'-g'
'--section-groups'
Displays the information contained in the file's section groups, if
it has any.
'-t'
'--section-details'
Displays the detailed section information. Implies '-S'.
'-s'
'--symbols'
'--syms'
Displays the entries in symbol table section of the file, if it has
one.
'--dyn-syms'
Displays the entries in dynamic symbol table section of the file,
if it has one.
'-U [D|I|L|E|X|H]'
'--unicode=[default|invalid|locale|escape|hex|highlight]'
Controls the display of non-ASCII characters in identifier names.
The default ('--unicode=locale' or '--unicode=default') is to treat
them as multibyte characters and display them in the current
locale. All other versions of this option treat the bytes as UTF-8
encoded values and attempt to interpret them. If they cannot be
interpreted or if the '--unicode=invalid' option is used then they
are displayed as a sequence of hex bytes, encloses in curly
parethesis characters.
Using the '--unicode=escape' option will display the characters as
as unicode escape sequences (\UXXXX). Using the '--unicode=hex'
will display the characters as hex byte sequences enclosed between
angle brackets.
Using the '--unicode=highlight' will display the characters as
unicode escape sequences but it will also highlighted them in red,
assuming that colouring is supported by the output device. The
colouring is intended to draw attention to the presence of unicode
sequences when they might not be expected.
'-e'
'--headers'
Display all the headers in the file. Equivalent to '-h -l -S'.
'-n'
'--notes'
Displays the contents of the NOTE segments and/or sections, if any.
'-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, as well as ARM unwind
tables ('.ARM.exidx' / '.ARM.extab') 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
hash tables in the file's dynamic section, rather than the symbol
table sections.
'-x <number or name>'
'--hex-dump=<number or name>'
Displays the contents of the indicated section as a hexadecimal
bytes. A number identifies a particular section by index in the
section table; any other string identifies all sections with that
name in the object file.
'-R <number or name>'
'--relocated-dump=<number or name>'
Displays the contents of the indicated section as a hexadecimal
bytes. A number identifies a particular section by index in the
section table; any other string identifies all sections with that
name in the object file. The contents of the section will be
relocated before they are displayed.
'-p <number or name>'
'--string-dump=<number or name>'
Displays the contents of the indicated section as printable
strings. A number identifies a particular section by index in the
section table; any other string identifies all sections with that
name in the object file.
'-z'
'--decompress'
Requests that the section(s) being dumped by 'x', 'R' or 'p'
options are decompressed before being displayed. If the section(s)
are not compressed then they are displayed as is.
'-c'
'--archive-index'
Displays the file symbol index information contained in the header
part of binary archives. Performs the same function as the 't'
command to 'ar', but without using the BFD library. *Note ar::.
'-w[lLiaprmfFsoRt]'
'--debug-dump[=rawline,=decodedline,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges,=pubtypes,=trace_info,=trace_abbrev,=trace_aranges,=gdb_index]'
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.
Note that there is no single letter option to display the content
of trace sections or .gdb_index.
Note: the '=decodedline' option will display the interpreted
contents of a .debug_line section whereas the '=rawline' option
dumps the contents in a raw format.
Note: the '=frames-interp' option will display the interpreted
contents of a .debug_frame section whereas the '=frames' option
dumps the contents in a raw format.
Note: the output from the '=info' option can also be affected by
the options '--dwarf-depth' and '--dwarf-start'.
'--dwarf-depth=N'
Limit the dump of the '.debug_info' section to N children. This is
only useful with '--debug-dump=info'. The default is to print all
DIEs; the special value 0 for N will also have this effect.
With a non-zero value for N, DIEs at or deeper than N levels will
not be printed. The range for N is zero-based.
'--dwarf-start=N'
Print only DIEs beginning with the DIE numbered N. This is only
useful with '--debug-dump=info'.
If specified, this option will suppress printing of any header
information and all DIEs before the DIE numbered N. Only siblings
and children of the specified DIE will be printed.
This can be used in conjunction with '--dwarf-depth'.
'-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'.
