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

• -mail=[e-mail] your email (meaningful if -errs option is used)

• -libfuncs decompile library functions too

• -usecache use cached microcode and pseudocode

• -tmpfile use a temp file for decompiled text to save memory

• -Dname=value apply a config directive

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:

idat -Ohexrays:-errs:-mail=[e-mail]:outfile:ALL -A input

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.
