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, --sec     
            tions, --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.
 
        -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 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 are currently sup‐
            ported.
 
        -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 <number>
        --hex-dump=<number>
            Displays  the  contents  of  the indicated section as a hexadecimal
            dump.
 
        -w[liaprmfFsoR]
        --debug-dump[=line,=info,=abbrev,=pub     
        names,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges]
            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 con‐
            tents 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.
