readelf
displays information about one or more ELF format object
files. The options control what particular information to display.
elffile… are the object files to be examined. At the
moment, readelf
does not support examining archives, nor does it
support examining 64 bit ELF files.
The long and short forms of options, shown here as alternatives, are equivalent. At least one option besides `-v' or `-H' must be given.
-a
--all
Equivalent to specifiying `--file-header', `--program-headers', `--sections', `--symbols', `--relocs', `--dynamic', `--notes' and `--version-info'.
-h
--file-header
Displays the information contained in the ELF header at the start of the file.
-l
--program-headers
--segments
Displays the information contained in the file's segment headers, if it has any.
-S
--sections
--section-headers
Displays the information contained in the file's section headers, if it has any.
-s
--symbols
--syms
Displays the entries in symbol table section of the file, if it has one.
-e
--headers
Display all the headers in the file. Equivalent to `-h -l -S'.
-n
--notes
Displays the contents of the NOTE segment, if it exists.
-r
--relocs
Displays the contents of the file's relocation section, if it has one.
-u
--unwind
Displays the contents of the file's unwind section, if it has one. Only the unwind sections for IA64 ELF files are currently supported.
-u
--unwind
Displays the contents of the file's unwind section, if it has one. Only the unwind sections for IA64 ELF files are currently supported.
-d
--dynamic
Displays the contents of the file's dynamic section, if it has one.
-V
--version-info
Displays the contents of the version sections in the file, it they exist.
-A
--arch-specific
Displays architecture-specific information in the file, if there is any.
-D
--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.
-x <number>
--hex-dump=<number>
Displays the contents of the indicated section as a hexadecimal dump.
-w[liaprmfFso]
--debug-dump[=line,=info,=abbrev,=pubnames,=ranges,=macro,=frames,=frames-interp,=str,=loc]
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.
-I
--histogram
Display a histogram of bucket list lengths when displaying the contents of the symbol tables.
-v
--version
Display the version number of readelf.
-W
--wide
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.
-H
--help
Display the command line options understood by readelf
.
