DESCRIPTION
`readelf' displays information about one or more ELF for
mat 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 examing 64 bit ELF files.
OPTIONS
The long and short forms of options, shown here as alter
natives, 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'
`--segments'
Displays the information contained in the file's seg
ment headers, if it has any.
`-S'
`--sections'
`--section-headers'
Displays the information contained in the file's sec
tion 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 sec
tion, 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.
`-d'
`--dynamic'
Displays the contents of the file's dynamic section,
if it has one.
`--version-info'
Displays the contents of the version sections in the
file, it they exist.
`-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[liaprf]'
`--debug-dump[=line,=info,=abbrev,=pub
names,=ranges,=frames]'
Displays the contents of the debug sections in the
file, if any are present. If one of the optional let
ters or words follows the switch then only data found
in those specific sections will be dumped.
`--histogram'
Display a histogram of bucket list lengths when dis
playing the contents of the symbol tables.
`-v'
`--version'
Display the version number of readelf.
`-H'
`--help'
Display the command line options understood by `read
elf'.
