Log Message:
-----------
- Correctly handle sections of type SHT_NOBITS. For these sections:
- elf_getdata() and elf_rawdata() should return an "Elf_Data" structure
that has its "d_buf" member set to NULL and "d_size" member set to
the nominal 'size' of the section. [1]
- Update the manual page for these functions.
Submitted by: kaiwang27 [1]
- Fix a memory leak in an error handling path inside elf_getdata().
- Use _libelf_allocate_data() in elf_newdata() for consistency.

+.Os
+.Sh NAME
+.Nm size
+.Nd "display section sizes and total size in"
+.Tn ELF
+files.
+.Sh SYNOPSIS
+.Nm
+.Op Fl Adhotx
+.Op Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility
+lists the size of various sections and total size (if choosen) for each input
+.Ar file.
+The
+.Nm
+utility can operate on ELF object,
+.Xr ar 1
+archives, and core dumps.
+.Pp
+If no file name is specified in the input, "a.out" is assumed.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl A
+The output of
+.Nm
+will resemble output from System V
+.Nm .
+By default, one line of output is generated for each ELF object or each module
+in an archive, if this option is not choosen.
+.It Fl t
+Shows cumulative totals of section sizes from all objects. Not available when
+System V output format
+.Fl A
+is choosen.
+.It Fl d | Fl o | Fl x
+The section sizes can be displayed either in decimal, octal or hexadecimal by
+choosing one of these options. Totals
+.Fl t
+are always displayed in two radixes; decimal and hexadecimal for
+.Fl d
+or
+.Fl x
+output, or octal and hexadecimal if
+.Fl o
+is choosen.
+.It Fl h
+This prints a usage summary and exits.
+.El
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+The following are examples of typical usage
+of the
+.Nm
+command:
+.Pp
+.Dl "$ size /bin/ls"
+.Dl "text data bss dec hex filename"
+.Dl "20975 540 392 21907 5593 /bin/ls"
+.Pp
+.Dl "$ size -tx /bin/ls /bin/dd"
+.Dl "text data bss dec hex filename"
+.Dl "0x51ef 0x21c 0x188 21907 5593 /bin/ls"
+.Dl "0x3df5 0x170 0x200 16741 4165 /bin/dd"
+.Dl "0x8fe4 0x38c 0x388 38648 96f8 (TOTALS)"
+.Sh SEE ALSO
+.Xr ar 1 ,
+.Xr objdump 1 ,
+.Xr readelf 1
+.Rs
+.%A "AT&T Unix Systems Labs"
+.%T "System V Application Binary Interface"
+.%O http://www.sco.com/developers/gabi/
+.Re
+.Sh HISTORY
+The
+.Nm
+utility first appeared in
+.At v6.
+The last FreeBSD
+.Nm
+was discontinued in
+.Fx v5 ,
+when i386-only a.out format was dropped in favor of ELF.
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+utility was re-written by
+.An S.Sam Arun Raj Aq sam...@gm...
+This manual page was written by
+.An S.Sam Arun Raj Aq sam...@gm...
+.Sh LIMITATIONS
+Unlike the GNU
+.Nm
+this doesn't support multiple object file formats, only ELF using the
+.Xr elf 3
+and
+.Xr gelf 3
+API's.

+.Sh NAME
+.Nm strings
+.Nd "print the strings of printable characters in files"
+.Sh SYNOPSIS
+.Nm
+.Op Fl afho
+.Op Fl e Ar encoding
+.Op Fl n Ar number
+.Op Fl t Ar radix
+.Op Ar
+.Sh DESCRIPTION
+Fo each
+.Ar file
+given, the
+.Nm
+utility prints any contiguous seqeunce of printable
+characters of atleast 'n' characters long (the default is 4 characters)
+followed by an unprintable character.
+.Nm
+only scans the initialized and loaded sections of ELF objects; for other
+file types, the entire file is scanned.
+The
+.Nm
+utility is mainly useful for determining the contents of non-text files.
+.Pp
+If no file name is specified in the input, standard input is read from.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl a
+This option instructs
+.Nm
+to scan the entire file. This is useful to override the default behaviour of
+scanning only initialized and loaded section of ELF objects.
+.It Fl e Ar encoding
+Select the character encoding to be used while searching for strings.
+The encoding depends on the single character argument which speicifes
+the encoding;
+.Ar s
+for single 7-bit-byte characters (ASCII, ISO 8859, etc., default).
+.Ar S
+for single 8-bit-byte characters.
+.Ar l
+for 16-bit littleendian.
+.Ar b
+for 16-bit bigendian.
+.Ar L
+for 32-bit littleendian.
+.Ar B
+for 32-bit bigendian.
+.It Fl f
+Print the name of the file before each string.
+.It Fl t Ar radix
+Print the offset from the start of the file before each string. The
+format depends on the single character argument which specifies the
+radix of the offset;
+.Ar d
+for decimal,
+.Ar o
+for octal,
+.Ar x
+for hexadecimal.
+.It Fl n Ar number
+Print the contiguous character sequence of alteast
+.Ar number
+characters long, instead of default 4 characters.
+.It Fl o
+This is same as -t o.
+.It Fl h
+This prints a usage summary and exits.
+.El
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+The following are examples of typical usage
+of the
+.Nm
+command:
+.Dl ""
+.Dl "$ strings /bin/ls"
+.Dl "$ strings -a /bin/ln"
+.Dl "$ strings -a -f -t x /bin/cat"
+.Sh SEE ALSO
+.Xr ar 1 ,
+.Xr nm 1 ,
+.Xr objdump 1 ,
+.Xr ranlib ,
+.Xr readelf 1
+.Sh HISTORY
+The first FreeBSD
+.Nm
+utility appeared in
+.Fx v3.
+It was later discontinued in
+.Fx v5 ,
+when i386-only a.out format was dropped in favor of ELF.
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+utility was re-written by
+.An S.Sam Arun Raj Aq sam...@gm...
+This manual page was written by

+.Sh LIMITATIONS
+Unlike the GNU
+.Nm
+this doesn't support multiple object file formats, only ELF using the
+.Xr elf 3
+and
+.Xr gelf 3
+API's.
