# Batch operation The decompiler supports the batch mode operation with the text and GUI versions of IDA. All you need is to specify the -Ohexrays switch in the command line. The format of this switch is: ``` -Ohexrays:-option1:-option2:outfile:func1:func2\... ``` The valid options are: * **-new** decompile only if output file does not exist * **-nosave** do not save the database (idb) file after decompilation * **-errs** send problematic databases to hex-rays.com * **-lumina** use Lumina server * **-mail=** your email (meaningful if **-errs** option is used) The output file name can be prepended with **+** to append to it. If the specified file extension is invalid, **.c** will be used. The functions to decompile can be specified by their addresses or names. The **ALL** keyword means all non-library functions. For example: ``` idat -Ohexrays:-errs:-mail=john@mail.com:outfile:ALL -A input ``` will decompile all nonlibrary functions to **outfile.c**. In the case of an error, the **.idb** file will be sent to **hex-rays.com**. The -A switch is necessary to avoid the initial dialog boxes. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
