My shell script does not read .env vars on Ubuntu 24.02.
```
$ gnome-shell --version
GNOME Shell 46.0
```
This my script.
```
//The script
#!/bin/sh
set +x
set +e
source .env 
clear
echo "Running flash loan simulation"
echo "PRIVATE_KEY: $PRIVATE_KEY"
echo "SEPOLIA_RPC_URL $SEPOLIA_RPC_URL"
echo "line 9"
cat .env
forge clean
forge build --force
```
When I cat the .env file in the same directory as the script.
```
$ cat .env
SEPOLIA_EQUALIZER_LENDER=xxxxxxxxxxxxxxxxxxxxxxxxxx
SEPOLIA_RPC_URL=https://sepolia.infura.io/v3/xxxxxxxxxxxxxx
PRIVATE_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
```
The terminal output. Interestingly the cat command does not list PRIVATE_KEY here.
```
Running flash loan simulation
PRIVATE_KEY: 
SEPOLIA_RPC_URL 
line 9
SEPOLIA_EQUALIZER_LENDER=0x0837b2aCcF87De52a099409863CDb5f3588342AD
SEPOLIA_RPC_URL=https://sepolia.infura.io/v3/xxxxxxx
# PRIVATE_KEY= is not listed here despite being listed in the cat command above
