NAME    [Toc]    [Back]

       readelf - Displays information about ELF files.

SYNOPSIS    [Toc]    [Back]

       readelf [-a|--all]
	       [-x <number>|--hex-dump=<number>]


DESCRIPTION    [Toc]    [Back]

       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.

OPTIONS    [Toc]    [Back]

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

	   Equivalent to specifiying --file-header, --program-headers,	--sec-
	   tions,  --symbols, --relocs, --dynamic, --notes and --version-info.

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

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

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

	   Displays the entries in symbol table section of the file, if it has

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

	   Displays the contents of the NOTE segment, if it exists.

	   Displays the contents of the file's relocation section, if  it  has

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

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

	   Displays the contents of the version sections in the file, it  they

	   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>
	   Displays  the  contents  of	the indicated section as a hexadecimal

	   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

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

	   Display the version number of readelf.

	   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.

	   Display the command line options understood by readelf.
