The long and short forms of options, shown here as alternatives, are
equivalent. At least one option besides -v or -H must be given.
Equivalent to specifiying --file-header, --program-headers, --sections,
--symbols, --relocs, --dynamic, --notes and --version-info.
Displays the information contained in the ELF header at the start
of the file.
Displays the information contained in the file’s segment headers,
if it has any.
Displays the information contained in the file’s section headers,
if it has any.
Displays the information contained in the file’s section groups, if
it has any.
Displays the detailed section information. Implies -S.
Displays the entries in symbol table section of the file, if it has
Display all the headers in the file. Equivalent to -h-l-S.
Displays the contents of the NOTE segments and/or sections, if any.
Displays the contents of the file’s relocation section, if it has
Displays the contents of the file’s unwind section, if it has one.
Only the unwind sections for IA64 ELF files are currently supported.
Displays the contents of the file’s dynamic section, if it has one.
Displays the contents of the version sections in the file, it they
Displays architecture-specific information in the file, if there is
When displaying symbols, this option makes readelf use the symbol
table in the file’s dynamic section, rather than the one in the
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.
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
Display a histogram of bucket list lengths when displaying the contents
of the symbol tables.
Display the version number of readelf.
Don’t break output lines to fit into 80 columns. By default readelf
breaks section header and segment listing lines for 64-bit ELF
files, so that they fit into 80 columns. This option causes readelf
to print each section header resp. each segment one a single line,
which is far more readable on terminals wider than 80 columns.
Display the command line options understood by readelf.
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
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.
