elf - command-line ELF object file header analyzerSynopsis
elf -[acdefmnoprstiuvxzAXIHV] [file]Description
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
