153 .IX Header "DESCRIPTION"
154 The \s-1GNU\s0 \fBsize\fR utility lists the section sizes and the total
155 size for each of the binary files \fIobjfile\fR on its argument list.
156 By default, one line of output is generated for each file or each
157 module if the file is an archive.
158 .PP
159 \&\fIobjfile\fR... are the files to be examined. If none are
160 specified, the file \f(CW\*(C`a.out\*(C'\fR will be used instead.
161 .SH "OPTIONS"
162 .IX Header "OPTIONS"
163 The command-line options have the following meanings:
164 .IP "\fB\-A\fR" 4
165 .IX Item "-A"
166 .PD 0
167 .IP "\fB\-B\fR" 4
168 .IX Item "-B"
169 .IP "\fB\-G\fR" 4
170 .IX Item "-G"
171 .IP "\fB\-\-format=\fR\fIcompatibility\fR" 4
172 .IX Item "--format=compatibility"
173 .PD
174 Using one of these options, you can choose whether the output from \s-1GNU\s0
175 \&\fBsize\fR resembles output from System V \fBsize\fR (using \fB\-A\fR,
176 or \fB\-\-format=sysv\fR), or Berkeley \fBsize\fR (using \fB\-B\fR, or
177 \&\fB\-\-format=berkeley\fR). The default is the one-line format similar to
178 Berkeley's. Alternatively, you can choose the \s-1GNU\s0 format output
179 (using \fB\-G\fR, or \fB\-\-format=gnu\fR), this is similar to
180 Berkeley's output format, but sizes are counted differently.
181 .Sp
182 Here is an example of the Berkeley (default) format of output from
183 \&\fBsize\fR:
184 .Sp
185 .Vb 4
186 \& $ size \-\-format=Berkeley ranlib size
187 \& text data bss dec hex filename
188 \& 294880 81920 11592 388392 5ed28 ranlib
189 \& 294880 81920 11888 388688 5ee50 size
190 .Ve
191 .Sp
192 The Berkeley style output counts read only data in the \f(CW\*(C`text\*(C'\fR
193 column, not in the \f(CW\*(C`data\*(C'\fR column, the \f(CW\*(C`dec\*(C'\fR and \f(CW\*(C`hex\*(C'\fR
194 columns both display the sum of the \f(CW\*(C`text\*(C'\fR, \f(CW\*(C`data\*(C'\fR, and
195 \&\f(CW\*(C`bss\*(C'\fR columns in decimal and hexadecimal respectively.
196 .Sp
197 The \s-1GNU\s0 format counts read only data in the \f(CW\*(C`data\*(C'\fR column, not
198 the \f(CW\*(C`text\*(C'\fR column, and only displays the sum of the \f(CW\*(C`text\*(C'\fR,
199 \&\f(CW\*(C`data\*(C'\fR, and \f(CW\*(C`bss\*(C'\fR columns once, in the \f(CW\*(C`total\*(C'\fR column.
200 The \fB\-\-radix\fR option can be used to change the number base for
201 all columns. Here is the same data displayed with \s-1GNU\s0 conventions:
202 .Sp
203 .Vb 4
204 \& $ size \-\-format=GNU ranlib size
205 \& text data bss total filename
206 \& 279880 96920 11592 388392 ranlib
207 \& 279880 96920 11888 388688 size
208 .Ve
209 .Sp
210 This is the same data, but displayed closer to System V conventions:
211 .Sp
212 .Vb 7
213 \& $ size \-\-format=SysV ranlib size
214 \& ranlib :

239 .IP "\fB\-\-radix=\fR\fInumber\fR" 4
240 .IX Item "--radix=number"
241 .PD
242 Using one of these options, you can control whether the size of each
243 section is given in decimal (\fB\-d\fR, or \fB\-\-radix=10\fR); octal
244 (\fB\-o\fR, or \fB\-\-radix=8\fR); or hexadecimal (\fB\-x\fR, or
245 \&\fB\-\-radix=16\fR). In \fB\-\-radix=\fR\fInumber\fR, only the three
246 values (8, 10, 16) are supported. The total size is always given in two
247 radices; decimal and hexadecimal for \fB\-d\fR or \fB\-x\fR output, or
248 octal and hexadecimal if you're using \fB\-o\fR.
249 .IP "\fB\-\-common\fR" 4
250 .IX Item "--common"
251 Print total size of common symbols in each file. When using Berkeley
252 or \s-1GNU\s0 format these are included in the bss size.
253 .IP "\fB\-t\fR" 4
254 .IX Item "-t"
255 .PD 0
256 .IP "\fB\-\-totals\fR" 4
257 .IX Item "--totals"
258 .PD
259 Show totals of all objects listed (Berkeley or \s-1GNU\s0 format mode only).
260 .IP "\fB\-\-target=\fR\fIbfdname\fR" 4
261 .IX Item "--target=bfdname"
262 Specify that the object-code format for \fIobjfile\fR is
263 \&\fIbfdname\fR. This option may not be necessary; \fBsize\fR can
264 automatically recognize many formats.
265 .IP "\fB\-V\fR" 4
266 .IX Item "-V"
267 .PD 0
268 .IP "\fB\-\-version\fR" 4
269 .IX Item "--version"
270 .PD
271 Display the version number of \fBsize\fR.
272 .IP "\fB@\fR\fIfile\fR" 4
273 .IX Item "@file"
274 Read command-line options from \fIfile\fR. The options read are
275 inserted in place of the original @\fIfile\fR option. If \fIfile\fR
276 does not exist, or cannot be read, then the option will be treated
277 literally, and not removed.
278 .Sp
279 Options in \fIfile\fR are separated by whitespace. A whitespace
280 character may be included in an option by surrounding the entire
281 option in either single or double quotes. Any character (including a
282 backslash) may be included by prefixing the character to be included
283 with a backslash. The \fIfile\fR may itself contain additional
284 @\fIfile\fR options; any such options will be processed recursively.
