.SH "DESCRIPTION"
.sp
The \fIarduino\fR integrated development environment allows editing, compiling and uploading sketches (programs) for Arduino (and compatible) microcontroller boards\&.
.sp
Normally, running the arduino command starts the IDE, optionally loading any \&.ino files specified on the commandline\&.
.sp
Alternatively, if any of the following command line options is given, no graphical interface will be shown and instead a one\-off verify (compile) or upload will be done\&. A single \&.ino file should be given\&. If the sketch contains multiple \&.ino files, any one can be specified on the commandline, but the entire sketch will be compiled\&.
.sp
When running in a one\-off mode, it might be useful to set the \fBbuild\&.path\fR preference to allow keeping intermediate build results between multiple runs and only recompile the files that changed\&.
.sp
Note that on MacOS X, the main executable is \fIArduino\&.app/Contents/MacOS/Arduino\fR instead of \fIarduino\fR\&.
.sp
Note that on Windows, due to the diffence between GUI and console apps, that the \fIarduino_debug\&.exe\fR is the appropriate executable to use if you want to use the majority of these command line options\&. The \fIarduino\&.exe\fR GUI version of the launcher \fBmay\fR perform some of the functions described below, but will not output any messages to the console, meaning it is pretty useless if you want any feedback or to be able to keep log files for automated testing, etc\&.
.sp

.RE
.PP
\fB\-\-port\fR \fIportname\fR
.RS 4

\fBCOM3\fR)\&.
.RE

\fBdisabled\fR
regardless of the current preferences\&.

\fB\-\-verbose\-upload\fR\&.
.RE
.PP
.RS 4
This option is only valid together with
\fB\-\-verify\fR

.RS 4
The path where sketches are (usually) stored\&. This path can also contain some special subdirectories (see FILES below)\&.

When set to true, use an external editor (the IDE does not allow editing and reloads each file before verifying)\&.
.RE
