Ghidra bulk file import with dynamic library search for portable executable files

ghidra_bulk_import.sh

#!/usr/bin/env bash
### Ghidra project bulk file import with DLL library resolution
### Warning, this file takes bloody ages to run! (40 minutes for 140 files)
### ... but it's still faster than using the GUI!

### EXAMPLE USAGE
# Import one file...
#   ./import.sh ./MyProject.gpr ./coredll.dll
# Import a list of files...
#   xargs -a ./list_of_files_to_import.txt -I{} ./import.sh ./MyProject.gpr {}

GPR_FILE="${1?}"
INPUT_FILE="${2?}"

# CHANGE THESE!!!
PROCESSOR='SuperH4:LE:32:default'
COMPILERSPEC='windows'
# This is needed if your DLLS live in a different folder, than the one your imported file lives in 
EXTRADLLSEARCHDIR='/path/to/your/DLL/files/folder/with/a/trailing/forward/slash/'
echo "$PROCESSOR"
echo "$COMPILERSPEC"
echo "$EXTRADLLSEARCHDIR"

## IMPORT ONLY VERSION, doesnt resolve libraries (faster?)
#$GHD "${PROJDIR}" "${PROJNAME}" \
#-processor $PROCESSOR -cspec $COMPILERSPEC \
#-import "${INPUT_FILE}"

### LOADER VERSION, resolves libraries, using flags from 'analyzeHeadlessREADME.html'
### If you aren't loading a PE file (Portable Executable), YOU WILL NEED TO CHANGE THESE SETTINGS!!!
### May need to be run multiple times, because files will depend on each other, and so will fail to link.
### Pay careful attention to the logs to figure that out!
