NAME
attdump - dump parts of an object or object archive file
SYNOPSIS
attdump [ options ] files
DESCRIPTION
The attdump command dumps selected parts of each of its file
arguments.
This command will accept object and archives of object files. It
processes each file argument according to one or more options. These
options are supported in both ELF and COFF environments:
-a Dump the archive header of each member of each archive file
argument.
-g Dump the global symbols in the symbol table of an archive.
-f Dump each file header.
-o Dump program header from ELF files; dump optional header
from COFF files.
-h Dump section headers.
-s Dump section contents.
-r Dump relocation information.
-l Dump line number information.
-t Dump symbol table entries.
-c Dump the string table.
-L Dump dynamic linking information and static shared library
information, if available.
These options are supported only in an ELF environment:
-C Dump decoded C++ symbol table names.
-D Dump DWARF debugging information.
-T index or -T index1,index2
Dump only the indexed symbol table entry defined by index
or a range of entries defined by index1,index2.
-V Print version information.
-u When reading a COFF object file, attdump translates the
file to ELF internally (this translation does not affect
the file contents). This option controls how much

translation occurs from COFF values to ELF. Normally
(without -u), the COFF values are preserved as much as
possible, showing the actual bytes in the file. If -u is
used, attdump updates the values and completes the
internal translation, giving a consistent ELF view of the
contents. Although the bytes displayed under this option
might not match the file itself, they show how the file
would look if it were converted to ELF. (See cof2elf(1)
for more information.)
This option is supported only in a COFF environment:
-z name Dump line number entries for the named function.
The following modifiers are used in conjunction with the options
listed above to modify their capabilities.
-n name Dump information pertaining only to the named entity.
This modifier applies to -h, -s, -r, -l, 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, whereas
dump -h -n .text will dump the section header information
for the .text section.
-p Suppress printing of the headers.
-v Dump information in symbolic representation rather than
numeric (e.g., C_STATIC instead of 0X02).
-d index Dump only the indexed section. In an ELF environment, you
may specify a range of sections as
-d start-index,end-index
In a COFF environment, use the +d modifier to specify a
range of sections:
-d start-index +d end-index
These modifiers are accepted only in a COFF environment:
+d index Dump the sections in the range ending with the indexed
section. The range begins at the first section or at the
section specified by the -d option.
-t index Dump only the indexed symbol table entry.
+t index Dump the symbol table entries in the range ending with the
indexed entry. The range begins at the first symbol table

entry or at the entry specified by the -t option.
-u Underline the name of the file for emphasis.
-z name,number
Dump the line number entry or range of line numbers
starting at number for the named function.
+z number Dump the line number entries starting at either function
name or line number specified by -z, up to number
specified by +z.
Blanks separating an option and its modifier are optional. The comma
separating the name from the number modifying the -z option may be
replaced by a blank.
The attdump command attempts to format the information it dumps in a
meaningful way, printing certain information in character, hex,
octal, or decimal representation as appropriate.
Although the command produces no output when invoked without options,
it does serve to verify that a file is an object, executable, or
archive of an object or executable.
