155 .IX Header "DESCRIPTION"
156 \&\fBelfedit\fR updates the \s-1ELF\s0 header of \s-1ELF\s0 files which have
157 the matching \s-1ELF\s0 machine and file types. The options control how and
158 which fields in the \s-1ELF\s0 header should be updated.
160 \&\fIelffile\fR... are the \s-1ELF\s0 files to be updated. 32\-bit and
161 64\-bit \s-1ELF\s0 files are supported, as are archives containing \s-1ELF\s0 files.
164 The long and short forms of options, shown here as alternatives, are
165 equivalent. At least one of the \fB\-\-output\-mach\fR,
166 \&\fB\-\-output\-type\fR and \fB\-\-output\-osabi\fR options must be given.
167 .IP "\fB\-\-input\-mach=\fR\fImachine\fR" 4
168 .IX Item "--input-mach=machine"
169 Set the matching input \s-1ELF\s0 machine type to \fImachine\fR. If
170 \&\fB\-\-input\-mach\fR isn't specified, it will match any \s-1ELF\s0
173 The supported \s-1ELF\s0 machine types are, \fIL1OM\fR, \fIK1OM\fR and
175 .IP "\fB\-\-output\-mach=\fR\fImachine\fR" 4
176 .IX Item "--output-mach=machine"
177 Change the \s-1ELF\s0 machine type in the \s-1ELF\s0 header to \fImachine\fR. The
178 supported \s-1ELF\s0 machine types are the same as \fB\-\-input\-mach\fR.
179 .IP "\fB\-\-input\-type=\fR\fItype\fR" 4
180 .IX Item "--input-type=type"
181 Set the matching input \s-1ELF\s0 file type to \fItype\fR. If
182 \&\fB\-\-input\-type\fR isn't specified, it will match any \s-1ELF\s0 file types.
184 The supported \s-1ELF\s0 file types are, \fIrel\fR, \fIexec\fR and \fIdyn\fR.
185 .IP "\fB\-\-output\-type=\fR\fItype\fR" 4
186 .IX Item "--output-type=type"
187 Change the \s-1ELF\s0 file type in the \s-1ELF\s0 header to \fItype\fR. The
188 supported \s-1ELF\s0 types are the same as \fB\-\-input\-type\fR.
189 .IP "\fB\-\-input\-osabi=\fR\fIosabi\fR" 4
190 .IX Item "--input-osabi=osabi"
191 Set the matching input \s-1ELF\s0 file \s-1OSABI\s0 to \fIosabi\fR. If
192 \&\fB\-\-input\-osabi\fR isn't specified, it will match any \s-1ELF\s0 OSABIs.
194 The supported \s-1ELF\s0 OSABIs are, \fInone\fR, \fI\s-1HPUX\s0\fR, \fINetBSD\fR,
195 \&\fI\s-1GNU\s0\fR, \fILinux\fR (alias for \fI\s-1GNU\s0\fR),

199 .IP "\fB\-\-output\-osabi=\fR\fIosabi\fR" 4
200 .IX Item "--output-osabi=osabi"
201 Change the \s-1ELF OSABI\s0 in the \s-1ELF\s0 header to \fIosabi\fR. The
202 supported \s-1ELF OSABI\s0 are the same as \fB\-\-input\-osabi\fR.
206 .IP "\fB\-\-version\fR" 4
209 Display the version number of \fBelfedit\fR.
213 .IP "\fB\-\-help\fR" 4
216 Display the command line options understood by \fBelfedit\fR.
217 .IP "\fB@\fR\fIfile\fR" 4
219 Read command-line options from \fIfile\fR. The options read are
220 inserted in place of the original @\fIfile\fR option. If \fIfile\fR
221 does not exist, or cannot be read, then the option will be treated
222 literally, and not removed.
224 Options in \fIfile\fR are separated by whitespace. A whitespace
225 character may be included in an option by surrounding the entire
226 option in either single or double quotes. Any character (including a
227 backslash) may be included by prefixing the character to be included
228 with a backslash. The \fIfile\fR may itself contain additional
229 @\fIfile\fR options; any such options will be processed recursively.
