        elffile... 

DESCRIPTION

readelf displays information about one or more ELF format objectfiles. The options control what particular information to display.

elffile... are the object files to be examined. At themoment, readelf does not support examining archives, nor does itsupport examing 64 bit ELF files. 

OPTIONS

The long and short forms of options, shown here as alternatives, areequivalent. At least one option besides -v or -H must begiven.
-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 thefile.
-l
--program-headers
--segments
Displays the information contained in the file's segment headers, if ithas any.
-S
--sections
--section-headers
Displays the information contained in the file's section headers, if ithas 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. Onlythe 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 theyexist.
-D
--use-dynamic
When displaying symbols, this option makes readelf use thesymbol table in the file's dynamic section, rather than the one in thesymbols 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,=str,=loc]
Displays the contents of the debug sections in the file, if any arepresent. If one of the optional letters or words follows the switchthen only data found in those specific sections will be dumped.
--histogram
Display a histogram of bucket list lengths when displaying the contentsof the symbol tables.
-v
--version
Display the version number of readelf.
-W
--wide
Don't break output lines to fit into 80 columns. By defaultreadelf breaks section header and segment listing lines for64-bit ELF files, so that they fit into 80 columns. This option causesreadelf to print each section header resp. each segment one asingle line, which is far more readable on terminals wider than 80 columns.
-H
--help
Display the command line options understood by readelf.
