+@unnumberedsubsubsec Standard shell commands
+
+If your shell (i.e. command window) supports normal redirects,
+then you might find it useful to use the following commands to
+redirect console output to a file:
+
+@itemize
+
+@item
+@code{lilypond file.ly 1>stdout.log} to redirect normal output
+
+@item
+@code{lilypond file.ly 2>stderr.log} to redirect error messages
+
+@item
+@code{lilypond file.ly &>all.log} to redirect all output
+
+@end itemize
+
+Consult the documentation for your shell to see if it supports these
+options, or if the syntax is different. Note that these are shell
+commands and have nothing to do with lilypond.

@node Command line options for lilypond
@unnumberedsubsec Command line options for @command{lilypond}
The @code{-dsafe} option works by evaluating in-line Scheme
expressions in a special safe module. This safe module is derived from
GUILE @file{safe-r5rs} module, but adds a number of functions of the
-LilyPond API. These functions are listed in @file{scm/@/safe@/-lily@/.scm}.
+LilyPond API. These functions are listed in @file{scm/safe-lily.scm}.
In addition, safe mode disallows @code{\include} directives and
disables the use of backslashes in @TeX{} strings.
@item -H,--header=@var{FIELD}
Dump a header field to file @file{BASENAME.@var{FIELD}}.
-@item --include, -I=@var{directory}
-Add @var{directory} to the search path for input files.
@cindex file searching
@cindex search path
+@item --include, -I=@var{directory}
+Add @var{directory} to the search path for input files.
+
+Multiple -I options may be given. The search will start in the
+first defined directory, and if the file to be included is not
+found the search will continue in subsequent directories.
@item -i,--init=@var{file}
Set init file to @var{file} (default: @file{init.ly}).
-@item -o,--output=@var{FILE}
-Set the default output file to @var{FILE}. The appropriate
-suffix will be added (e.g. @code{.pdf} for pdf)

+Set the default output file to @var{FILE} or, if a folder with
+that name exists, direct the output to @var{FOLDER}, taking the
+file name from the input file. The appropriate suffix will be
+added (e.g. @code{.pdf} for pdf) in both cases.
