NAME
       elf - command-line ELF object file header analyzer

SYNOPSIS
       elf -[acdefmnoprstiuvxzAXIHV] [file]

DESCRIPTION
       elf  is	an  ELF	 header	 (e_header)  statistics	tool. It allows	you to
       gather various  statistics about	a binary's  ELF	 header,  elf  concen-
       trates  on  the e_header	itself.	This allows for	some more usability in
       many instances (be it by	an end-user or application).

       ELF is the acroynm for "executable and  linkable	 format".  It  is  the
       standard	executable format amongst most modern UNIX and UNIX-like oper-
       ating systems. For more information consult your	local ELF header  file
       (usually	/usr/include/elf.h).

       For  a  list  of	elf's current features,	please use the help command in
       elf.

COMMANDLINE OPTIONS
       elf has many command-line options to allow verbose  information	to  be
       presented based on the values inside a file's ELF header	(if existant).

       -a output ABI of	selected ELF object file

       -c output class-object sizes

       -d output data encoding type

       -e output virtual entry point

       -f output processor specific flags

       -m output architecture meant for	object file

       -n output program header	entry count

       -o output section header	entry size

       -p output program header	offset

       -r output ELF header size

       -s output section header	offset (in bytes)

       -t output ELF object file type

       -i output ELF magic values

       -u output section header	entry count

       -v output ELF version used in object file

       -x output section header	string index

       -z output program header	entry size

       -A output all information provided by ELF header

       -X output any selected information in hex

       -I output any selected information in decimal (base 10)

       -H output any selected information in  human-centric  values  (default)
       Geeks may use above options

       -V this sets level of verbosity.	The more times repeated, the more ver-
       bose output will	be

INTERACTIVE MODE OPTIONS
       There are many options in  elf's	 interactive  mode  to	show  specific
       information about the ELF header.  These	options	can be listed with the
       following command: (elf)	help info

       These are the info Options:

       ALL

       Show all	of the ELF header information.

       IDENT

       Show ELF	header ident.

       CLASS

       Show class object sizes.

       DATA

       Show data encoding.

       ABI

       Show ELF	header operating system	ABI.

       TYPE

       Show ELF	object file type.

       MACHINE

       Show ELF	object file machine information.

       VERSION

       Show ELF	version	of object file.

       ENTRY

       Show virtual entry point	of ELF object file.

       PHOFF

       Show program header offset.

       FLAGS

       Show processor specific flags of	object file

       EHSIZE

       Show ELF	header size.

       PHENTSIZE

       Show program entry size.

       PHNUM

       Show number of program header entries.

       SHENTSIZE

       Show section header entry size.

       SHNUM

       Show number of section header entries.

       SHSTRNDX

       Show section header string table	index.

       There are also three modifiers that can be used with the	above options.
       They are:

       hex

       Show the	output in hex format.

       int

       Show the	output in integer format.

       hum

       Show the	output in human	readable format
