27 !!DESCRIPTION
28
29
30 __readelf__ displays information about one or more
31 ELF format object files. The options control
32 what particular information to display.
33
34
35 ''elffile''... are the object files to be examined. At
36 the moment, __readelf__ does not support examining
37 archives, nor does it support examing 64 bit
38 ELF files.
39 !!OPTIONS
40
41
42 The long and short forms of options, shown here as
43 alternatives, are equivalent. At least one option besides
44 __-v__ or __-H__ must be given.
45
46
47 __-a__
48
49
50 __--all__
51
52
53 Equivalent to specifiying __--file-header__,
54 __--program-headers__, __--sections__,
55 __--symbols__, __--relocs__, __--dynamic__,
56 __--notes__ and __--version-info__.
57

59 __-h__
60
61
62 __--file-header__
63
64
65 Displays the information contained in the ELF
66 header at the start of the file.

68
69 __-l__
70
71
72 __--program-headers__
73
74
75 __--segments__
76

79 headers, if it has any.

82 __-S__
83
84
85 __--sections__
86
87
88 __--section-headers__
89
90
91 Displays the information contained in the file's section
92 headers, if it has any.
93
94
95 __-s__
96
97
98 __--symbols__
99
100
101 __--syms__
102
103
104 Displays the entries in symbol table section of the file, if
105 it has one.
106
107
108 __-e__
109
110
111 __--headers__
112
113
114 Display all the headers in the file. Equivalent to __-h -l
115 -S__.
116
117
118 __-n__
119
120
121 __--notes__
122
123
124 Displays the contents of the NOTE segment, if
125 it exists.
126
127
128 __-r__
129
130
131 __--relocs__
132
133
134 Displays the contents of the file's relocation section, if
135 it has one.
136
137
138 __-u__
139
140
141 __--unwind__
142
143
144 Displays the contents of the file's unwind section, if it
145 has one. Only the unwind sections for IA64
146 ELF files are currently supported.
147
148
149 __-d__
150
151
152 __--dynamic__
153
154
155 Displays the contents of the file's dynamic section, if it
156 has one.
157
158
159 __-V__
160
161
162 __--version-info__
163
164
165 Displays the contents of the version sections in the file,
166 it they exist.
167
168
169 __-D__
170
171
172 __--use-dynamic__
173
174
175 When displaying symbols, this option makes __readelf__
176 use the symbol table in the file's dynamic section, rather
177 than the one in the symbols section.
178
179
180 __-x __
181
182
183 __--hex-dump=__
184
185
186 Displays the contents of the indicated section as a
187 hexadecimal dump.
188
189
190 __-w[[liaprmfs]__
191
192
193 __--debug-dump[[=line,=info,=abbrev,=pubnames,=ranges,=macro,=frames,=str]__
194
195
196 Displays the contents of the debug sections in the file, if
197 any are present. If one of the optional letters or words
198 follows the switch then only data found in those specific
199 sections will be dumped.
200
201
202 __--histogram__
203
204
205 Display a histogram of bucket list lengths when displaying
206 the contents of the symbol tables.
207
208
209 __-v__
210
211
212 __--version__
213
214
215 Display the version number of readelf.
216
217
218 __-W__
219
220
221 __--wide__
222
223
224 Don't break output lines to fit into 80 columns. By default
225 __readelf__ breaks section header and segment listing
226 lines for 64-bit ELF files, so that they fit
227 into 80 columns. This option causes __readelf__ to print
228 each section header resp. each segment one a single line,
229 which is far more readable on terminals wider than 80
230 columns.
231
232
233 __-H__
234
235
236 __--help__
237
238
239 Display the command line options understood by
240 __readelf__.
