Running in Batch Mode

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.

Step 1: Understanding the Switch Format

All batch mode configuration is passed through a single command-line switch. The format of this switch is:

-Ohexrays:-option1:-option2...:outfile:func1:func2\...

Step 2: Choose Your Options

Select the options relevant to your use case; all are optional.

  • -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

  • [email protected] 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.

Step 3: Specify Functions to Decompile

The functions to decompile can be specified by their addresses or names.

The ALL keyword means all non-library non-trivial functions.

Example:

The example above will decompile all non-library, non-trivial (having more than one instruction) 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.
