.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBelfedit\fR updates the \s-1ELF\s0 header of \s-1ELF\s0 files which have
the matching \s-1ELF\s0 machine and file types.  The options control how and
which fields in the \s-1ELF\s0 header should be updated.
.PP
\&\fIelffile\fR... are the \s-1ELF\s0 files to be updated.  32\-bit and
64\-bit \s-1ELF\s0 files are supported, as are archives containing \s-1ELF\s0 files.
.SH "OPTIONS"
.IX Header "OPTIONS"
The long and short forms of options, shown here as alternatives, are
equivalent. At least one of the \fB\-\-output\-mach\fR,
\&\fB\-\-output\-type\fR and \fB\-\-output\-osabi\fR options must be given.
.IP "\fB\-\-input\-mach=\fR\fImachine\fR" 4
.IX Item "--input-mach=machine"
Set the matching input \s-1ELF\s0 machine type to \fImachine\fR.  If
\&\fB\-\-input\-mach\fR isn't specified, it will match any \s-1ELF\s0
machine types.
.Sp
The supported \s-1ELF\s0 machine types are, \fIi386\fR, \fI\s-1IAMCU\s0\fR, \fIL1OM\fR,
\&\fIK1OM\fR and \fIx86\-64\fR.
.IP "\fB\-\-output\-mach=\fR\fImachine\fR" 4
.IX Item "--output-mach=machine"
Change the \s-1ELF\s0 machine type in the \s-1ELF\s0 header to \fImachine\fR.  The
supported \s-1ELF\s0 machine types are the same as \fB\-\-input\-mach\fR.
.IP "\fB\-\-input\-type=\fR\fItype\fR" 4
.IX Item "--input-type=type"
Set the matching input \s-1ELF\s0 file type to \fItype\fR.  If
\&\fB\-\-input\-type\fR isn't specified, it will match any \s-1ELF\s0 file types.
.Sp
The supported \s-1ELF\s0 file types are, \fIrel\fR, \fIexec\fR and \fIdyn\fR.
.IP "\fB\-\-output\-type=\fR\fItype\fR" 4
.IX Item "--output-type=type"
Change the \s-1ELF\s0 file type in the \s-1ELF\s0 header to \fItype\fR.  The
supported \s-1ELF\s0 types are the same as \fB\-\-input\-type\fR.
.IP "\fB\-\-input\-osabi=\fR\fIosabi\fR" 4
.IX Item "--input-osabi=osabi"
Set the matching input \s-1ELF\s0 file \s-1OSABI\s0 to \fIosabi\fR.  If
\&\fB\-\-input\-osabi\fR isn't specified, it will match any \s-1ELF\s0 OSABIs.
.Sp
The supported \s-1ELF\s0 OSABIs are, \fInone\fR, \fI\s-1HPUX\s0\fR, \fINetBSD\fR,
\&\fI\s-1GNU\s0\fR, \fILinux\fR (alias for \fI\s-1GNU\s0\fR),

.IP "\fB\-\-output\-osabi=\fR\fIosabi\fR" 4
.IX Item "--output-osabi=osabi"
Change the \s-1ELF OSABI\s0 in the \s-1ELF\s0 header to \fIosabi\fR.  The
supported \s-1ELF OSABI\s0 are the same as \fB\-\-input\-osabi\fR.
.IP "\fB\-v\fR" 4
.IX Item "-v"
.PD 0
.IP "\fB\-\-version\fR" 4
.IX Item "--version"
.PD
Display the version number of \fBelfedit\fR.
.IP "\fB\-h\fR" 4
.IX Item "-h"
.PD 0
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
.PD
Display the command line options understood by \fBelfedit\fR.
.IP "\fB@\fR\fIfile\fR" 4
.IX Item "@file"
Read command-line options from \fIfile\fR.  The options read are
inserted in place of the original @\fIfile\fR option.  If \fIfile\fR
does not exist, or cannot be read, then the option will be treated
literally, and not removed.
.Sp
Options in \fIfile\fR are separated by whitespace.  A whitespace
character may be included in an option by surrounding the entire
option in either single or double quotes.  Any character (including a
backslash) may be included by prefixing the character to be included
with a backslash.  The \fIfile\fR may itself contain additional
@\fIfile\fR options; any such options will be processed recursively.
