User Commands dump(1)
NAME
dump - dump selected parts of an object file
SYNOPSIS
dump [-aCcfghLorstV [-p]] [ -T index [ , indexn]]
filename...
dump [ -afhorstL [-p] [v]] filename...
dump [ -hsr [-p] [ -d number [ , numbern]]] filename...
dump [ -hsrt [-p] [-n name]] filename...
DESCRIPTION
The dump utility dumps selected parts of each of its object
file arguments.
The dump utility is best suited for use in shell scripts,
whereas the elfdump(1) command is recommended for more
human-readable output.
OPTIONS
This utility will accept both object files and archives of
object files. It processes each file argument according to
one or more of the following options:
-a Dumps the archive header of each
member of an archive.
-c Dumps the string table(s).
-C Dumps decoded C++ symbol table
names.
-f Dumps each file header.
-g Dumps the global symbols in the sym-
bol table of an archive.
-h Dumps the section headers.

User Commands dump(1)
-L Dumps dynamic linking information
and static shared library informa-
tion, if available.
-o Dumps each program execution header.
-r Dumps relocation information.
-s Dumps section contents in hexade-
cimal.
-t Dumps symbol table entries.
-T index Dumps only the indexed symbol table
-T index1,index2 entry defined by index or a range of
entries defined by index1,index2.
-V Prints version information.
The following modifiers are used in conjunction with the
options listed above to modify their capabilities.
-d number Dumps the section number indicated
-d number1,number2 by number or the range of sections
starting at number1 and ending at
number2. This modifier can be used
with -h, -s, and -r. When -d is used
with -h or -s, the argument is
treated as the number of a section
or range of sections. When -d is
used with -r, the argument is
treated as the number of the section
or range of sections to which the
relocation applies. For example, to
print out all relocation entries
associated with the .text section,
specify the number of the section as

the argument to -d. If .text is sec-
tion number 2 in the file, dump -r
-d 2 will print all associated
entries. To print out a specific
relocation section, use dump -s -n
name for raw data output, or dump
-sv -n name for interpreted output.
-n name Dumps information pertaining only to
the named entity. This modifier can
be used with -h, -s, -r, and -t.
When -n is used with -h or -s, the
argument will be treated as the name
of a section. When -n is used with
-t or -r, the argument will be
treated as the name of a symbol. For
example, dump -t -n .text will dump
the symbol table entry associated
with the symbol whose name is .text,
where dump -h -n .text will dump
the section header information for
the .text section.
-p Suppresses printing of the headings.
-v Dumps information in symbolic
representation rather than numeric.
This modifier can be used with
-a (date, user id, group id)
-f (class, data, type,
machine, version, flags)
-h (type, flags)
-L (value)

User Commands dump(1)
-o (type, flags)
-r (name, type)
-s (interpret section contents
wherever possible)
-t (type, bind)
When -v is used with -s, all sec-
tions that can be interpreted, such
as the string table or symbol table,
will be interpreted. For example,
dump -sv -n .symtab filename... will
produce the same formatted output as
dump -tv filename..., but dump -s -n
.symtab filename... will print raw
data in hexadecimal. Without addi-
tional modifiers, dump -sv
filename... will dump all sections
in the files, interpreting all those
that it can and dumping the rest
(such as .text or .data) as raw
data.
The dump utility attempts to format the information it dumps
in a meaningful way, printing certain information in charac-
ter, hexadecimal, octal, or decimal representation as
appropriate.
