Don't break output lines to fit into 80 columns. By default
|
||
|
|
\&\fBreadelf\fR breaks section header and segment listing lines for
|
||
|
|
64\-bit \s-1ELF\s0 files, so that they fit into 80 columns. This option causes
|
||
|
|
\&\fBreadelf\fR to print each section header resp. each segment one a
|
||
|
|
single line, which is far more readable on terminals wider than 80 columns.

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.

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.
