Options in file are separated by whitespace. If file does not exist, orĬannot be read, then the option will be treated literally, and not removed. The options read are inserted in place of the original file option. H -help Display the command line options understood by file Read command-line options from file. Readable on terminals wider than 80 columns. each segment one a single line, which is far more This option causes readelf to print each section header resp. By default readelf breaks section header and segment listing lines for 64-bit ELFįiles, so that they fit into 80 columns. W -wide Don't break output lines to fit into 80 columns. v -version Display the version number of readelf. I -histogram Display a histogram of bucket list lengths when displaying the contents of the symbol tables. debug_line section whereas the =rawline option dumps the contents in Note: the =decodedline option will display the interpreted contents of a. In those specific sections will be dumped. If one of the optional letters or words follows the switch then only data found w -debug-dump Displays the contents of the debug sections in the file, if any are present. Performs the same function as the t command to ar, c -archive-index Displays the file symbol index infomation contained in the header part of binary archives. A number identifies a particular section by index in the section table any other p -string-dump= Displays the contents of the indicated section as printable strings. The contents of the section will be relocated before they are displayed. String identifies all sections with that name in the object file. R -relocated-dump= Displays the contents of the indicated section as a hexadecimal bytes.
x -hex-dump= Displays the contents of the indicated section as a hexadecimal bytes. 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 A -arch-specific Displays architecture-specific information in the file, if there is any. V -version-info Displays the contents of the version sections in the file, it they exist. d -dynamic Displays the contents of the file's dynamic section, if it has one. Only the unwind sections for IA64 ELF files are currently u -unwind Displays the contents of the file's unwind section, if it has one. r -relocs Displays the contents of the file's relocation section, if it has one. n -notes Displays the contents of the NOTE segments and/or sections, if any. e -headers Display all the headers in the file. s -symbols -syms Displays the entries in symbol table section of the file, if it has one. t -section-details Displays the detailed section information. g -section-groups Displays the information contained in the file's section groups, if it has any. S -sections -section-headers Displays the information contained in the file's section headers, if it has any. l -program-headers -segments Displays the information contained in the file's segment headers, if it has any. h -file-header Displays the information contained in the ELF header at the start of the file. a -all Equivalent to specifying -file-header, -program-headers, -sections, -symbols, -relocs, -dynamic, At least one option besides -v or -H must be given. The long and short forms of options, shown here as alternatives, are equivalent. There is a bug in BFD then readelf will not be affected.
This program performs a similar function to objdump but it goes into more detail and it exists independently of the BFD library, so if 32-bit and 64-bit ELF files are supported, as are archives containing The options control what particular information to display.Įlffile.
Readelf displays information about one or more ELF format object files.
