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
       concentrates 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
       operating 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
       verbose 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
