        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.  At the
moment, readelf does not support examining archives, nor
does it support examing 64 bit ELF files.

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.









                             ‐2‐


−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.

−D










                             ‐3‐


−−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 <number>

−−hex−dump=<number>
    Displays the contents of the indicated section as a
    hexadecimal dump.

−w[liaprmfFso]

−−debug−dump[=line,=info,=abbrev,=pubnames,=ranges,=macro,=frames,=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.

−−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.

objdump(1), and the Info entries for binutils.
