DESCRIPTION

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

_e_l_f_f_i_l_e... 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 oobbjjdduummpp 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 --vv or --HH must be given.
--aa
----aallll Equivalent to specifiying ----ffiillee--hheeaaddeerr,
----pprrooggrraamm--hheeaaddeerrss, ----sseeccttiioonnss, ----ssyymmbboollss, ----rreellooccss, ----ddyynnaammiicc, ----nnootteess and ----vveerrssiioonn--iinnffoo.
--hh
----ffiillee--hheeaaddeerr Displays the information contained in the ELF header at the start of the
file.
--ll
----pprrooggrraamm--hheeaaddeerrss
----sseeggmmeennttss Displays the information contained in the file's segment headers, if it
has any.
--SS
----sseeccttiioonnss
----sseeccttiioonn--hheeaaddeerrss Displays the information contained in the file's section headers, if it
has any.
--gg
----sseeccttiioonn--ggrroouuppss Displays the information contained in the file's section groups, if it
has any.
--ss
----ssyymmbboollss
----ssyymmss Displays the entries in symbol table section of the file, if it has one.
--ee
----hheeaaddeerrss Display all the headers in the file. Equivalent to --hh --ll --SS.
--nn
----nnootteess Displays the contents of the NOTE segments and/or sections, if any.
--rr
----rreellooccss Displays the contents of the file's relocation section, if it has one.
--uu
----uunnwwiinndd Displays the contents of the file's unwind section, if it has one. Only
the unwind sections for IA64 ELF files are currently supported.
--dd
----ddyynnaammiicc Displays the contents of the file's dynamic section, if it has one.
--VV
----vveerrssiioonn--iinnffoo Displays the contents of the version sections in the file, it they
exist.
--AA
----aarrcchh--ssppeecciiffiicc Displays architecture-specific information in the file, if there
is any.
--DD
----uussee--ddyynnaammiicc When displaying symbols, this option makes rreeaaddeellff use the
symbol table in the file's dynamic section, rather than the one in the symbols section.
--xx <>
----hheexx--dduummpp==<> Displays the contents of the indicated section as a hexadecimal dump.
--ww[[lliiaapprrmmffFFssooRR]]
----ddeebbuugg--dduummpp[[==lliinnee,,==iinnffoo,,==aabbbbrreevv,,==ppuubbnnaammeess,,==aarraannggeess,,==mmaaccrroo,,==ffrraammeess,,==ffrraammeess--iinntteerrpp,,==ssttrr,,==lloocc,,==RRaannggeess]] 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.
--II
----hhiissttooggrraamm Display a histogram of bucket list lengths when displaying the contents
of the symbol tables.
--vv
----vveerrssiioonn Display the version number of readelf.
--WW
----wwiiddee Don't break output lines to fit into 80 columns. By default
rreeaaddeellff breaks section header and segment listing lines for 64-bit ELF files, so that they fit into 80 columns. This option causes rreeaaddeellff to print each section header resp. each segment one a single line, which is far more readable on terminals wider than 80 columns.
--HH
----hheellpp Display the command line options understood by rreeaaddeellff.
