.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. | will give a
real vertical bar. \*(C+ will give a nicer C++. Capital omega is used to
do unbreakable dashes and therefore won't be available. \*(C` and \*(C'
expand to `' in nroff, nothing in troff, for use with C<>.

If the F register is turned on, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.Sh), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.

Title "READELF 1" readelf - Displays information about ELF files. Header "SYNOPSIS" readelf [-a|--all] [-h|--file-header] [-l|--program-headers|--segments] [-S|--section-headers|--sections] [-g|--section-groups] [-t|--section-details] [-e|--headers] [-s|--syms|--symbols] [-n|--notes] [-r|--relocs] [-u|--unwind] [-d|--dynamic] [-V|--version-info] [-A|--arch-specific] [-D|--use-dynamic] [-x <number or name>|--hex-dump=<number or name>] [-p <number or name>|--string-dump=<number or name>] [-c|--archive-index] [-w[lLiaprmfFsoR]| --debug-dump[=rawline,=decodedline,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges]] [-I|-histogram] [-v|--version] [-W|--wide] [-H|--help] elffile... Header "DESCRIPTION" \fBreadelf displays information about one or more \s-1ELF\s0 format object files. The options control what particular information to display.

\fIelffile... are the object files to be examined. 32-bit and 64-bit \s-1ELF\s0 files are supported, as are archives containing \s-1ELF\s0 files.

This program performs a similar function to objdump but it goes into more detail and it exists independently of the \s-1BFD\s0 library, so if there is a bug in \s-1BFD\s0 then readelf will not be affected.

Header "OPTIONS" The long and short forms of options, shown here as alternatives, are equivalent. At least one option besides -v or -H must be given. Item "-a"

0

Item "--all"

Equivalent to specifying --file-header, \fB--program-headers, --sections, --symbols, \fB--relocs, --dynamic, --notes and \fB--version-info.

Item "-h"

0

Item "--file-header"

Displays the information contained in the \s-1ELF\s0 header at the start of the file.

Item "-l"

0

Item "--program-headers" Item "--segments"

Displays the information contained in the file's segment headers, if it has any.

Item "-S"

0

Item "--sections" Item "--section-headers"

Displays the information contained in the file's section headers, if it has any.

Item "-g"

0

Item "--section-groups"

Displays the information contained in the file's section groups, if it has any.

Item "-t"

0

Item "--section-details"

Displays the detailed section information. Implies -S.

Item "-s"

0

Item "--symbols" Item "--syms"

Displays the entries in symbol table section of the file, if it has one.

Item "-e"

0

Item "--headers"

Display all the headers in the file. Equivalent to -h -l -S.

Item "-n"

0

Item "--notes"

Displays the contents of the \s-1NOTE\s0 segments and/or sections, if any.

Item "-r"

0

Item "--relocs"

Displays the contents of the file's relocation section, if it has one.

Item "-u"

0

Item "--unwind"

Displays the contents of the file's unwind section, if it has one. Only the unwind sections for \s-1IA64\s0 \s-1ELF\s0 files are currently supported.

Item "-d"

0

Item "--dynamic"

Displays the contents of the file's dynamic section, if it has one.

Item "-V"

0

Item "--version-info"

Displays the contents of the version sections in the file, it they exist.

Item "-A"

0

Item "--arch-specific"

Displays architecture-specific information in the file, if there is any.

Item "-D"

0

Item "--use-dynamic"

When displaying symbols, this option makes readelf use the symbol table in the file's dynamic section, rather than the one in the symbols section.

Item "-x <number or name>"

0

Item "--hex-dump=<number or name>"

Displays the contents of the indicated section as a hexadecimal dump. A number identifies a particular section by index in the section table; any other string identifies all sections with that name in the object file.

Item "-p <number or name>"

0

Item "--string-dump=<number or name>"

Displays the contents of the indicated section as printable strings. A number identifies a particular section by index in the section table; any other string identifies all sections with that name in the object file.

Item "-c"

0

Item "--archive-index"

Displays the file symbol index infomation contained in the header part of binary archives. Performs the same function as the t command to ar, but without using the \s-1BFD\s0 library.

Item "-w[lLiaprmfFsoR]"

0

Item "--debug-dump[=rawline,=decodedline,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges]"

Displays the contents of the debug sections in the file, if any are present. If one of the optional letters or words follows the switch then only data found in those specific sections will be dumped. .Sp Note: the =decodedline option will display the interpreted contents of a .debug_line section whereas the =rawline option dumps the contents in a raw format.

Item "-I"

0

Item "--histogram"

Display a histogram of bucket list lengths when displaying the contents of the symbol tables.

Item "-v"

0

Item "--version"

Display the version number of readelf.

Item "-W"

0

Item "--wide"

Don't break output lines to fit into 80 columns. By default \fBreadelf breaks section header and segment listing lines for 64-bit \s-1ELF\s0 files, so that they fit into 80 columns. This option causes \fBreadelf to print each section header resp. each segment one a single line, which is far more readable on terminals wider than 80 columns.

Item "-H"

0

Item "--help"

Display the command line options understood by readelf.

Item "@file" Read command-line options from file. The options read are inserted in place of the original @file option. If file does not exist, or cannot be read, then the option will be treated literally, and not removed. .Sp Options in file are separated by whitespace. A whitespace character may be included in an option by surrounding the entire option in either single or double quotes. Any character (including a backslash) may be included by prefixing the character to be included with a backslash. The file may itself contain additional @file options; any such options will be processed recursively. Header "SEE ALSO" \fIobjdump\|(1), and the Info entries for binutils.
