elf(1) General Commands Manual elf(1) 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/in- clude/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 pre- sented 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 informa- tion 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 SEE ALSO as(1), gdb(1), ld(1), execve(2), core(5), elf(5), link(5) AUTHORS Samy Al Bahra <samy@kerneled.com> CONTRIBUTORS Eirik Nygaard <eirikn@bluezone.no> , Vanya Sergeev DISTRIBUTION The latest version of elf can be obtained from http://www.kerneled.com/projects/elf/index.html Consult the GNU General Public License for more information (it is located in the COPYING file of the elf distribution).
