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
Dumps the archive header of each member of an
Dumps the string table(s).
Dumps decoded symbol table names.
Dumps each file header.
Dumps the global symbols in the symbol table of an
Dumps the section headers.
Dumps dynamic linking information and static shared
library information, if available.
Dumps each program execution header.
Dumps relocation information.
Dumps section contents in hexadecimal.
Dumps symbol table entries.
Dumps only the indexed symbol table entry defined by
index or a range of entries defined by
Prints version information.
The following modifiers are used in conjunction with the options
listed above to modify their capabilities.
Dumps the section number indicated 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 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 interpreted
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.
Suppresses printing of the headings.
Dumps information in symbolic representation rather than
numeric. This modifier can be used with
(date, user id, group id)
(class, data, type, machine, version, flags)
(interpret section contents wherever possible)
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
filename..., 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 meaningful way, printing certain information in character,
hexadecimal, octal, or decimal representation as appropriate.
