dump(1) User Commands dump(1)
dump - dump selected parts of an object file
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...
The dump utility dumps selected parts of each of its object file argu-
The dump utility is best suited for use in shell scripts, whereas the
elfdump(1) command is recommended for more human-readable output.
This utility will accept both object files and archives of object
files. It processes each file argument according to one or more of the
-a Dumps the archive header of each member of an
-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 symbol table of
-h Dumps the section headers.
-L Dumps dynamic linking information and static
shared library information, if available.
-o Dumps each program execution header.
-r Dumps relocation information.
-s Dumps section contents in hexadecimal.
-t Dumps symbol table entries.
-T index Dumps only the indexed symbol table entry
-T index1,index2 defined by index or a range of entries defined
-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 by number or
-d number1,number2 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 sec-
tion as the argument to -d. If .text is section
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 inter-
-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 sec-
tion. When -n is used with -t or -r, the argu-
ment 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
-a (date, user id, group id)
-f (class, data, type, machine, version,
-h (type, flags)
-o (type, flags)
-r (name, type)
-s (interpret section contents wherever
-t (type, bind)
When -v is used with -s, all sections 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 file-
name..., but dump -s -n .symtab filename...
will print raw data in hexadecimal. Without
additional 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 mean-
ingful way, printing certain information in character, hexadecimal,
octal, or decimal representation as appropriate.
