Unrecognized GHIDRA_INSTALL_DIR

[D3vil0p3r]

Just for sport I'm diff the same .exe file, and set GHIDRA_INSTALL_DIR as:

set GHIDRA_INSTALL_DIR "/opt/ghidra/"
echo $GHIDRA_INSTALL_DIR
/opt/ghidra/

and then I run:

ghidriff NETReactorSlayer.CLI.exe NETReactorSlayer.CLI.exe

but I get:

INFO | ghidriff | Init Ghidra Diff Engine...
INFO | ghidriff | Engine Console Log: INFO

Why does it not recognize the env variable?

[clearbluejar]

Normally I use export GHIDRA_INSTALL_DIR=/path/to/ghidra

This is what I use for my docker containers https://github.com/clearbluejar/features/blob/7b5586189b350764ad8b3e95afe792348cc73cef/src/ghidra/install.sh#L144

I don't know the subtle difference between set and export, but maybe this https://unix.stackexchange.com/questions/71144/what-do-the-bash-builtins-set-and-export-do ?
