My script can't read .env variables

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 [⠊] Compiling...4d6a4949fa623629e0ED6bd4Ecb78A8C847693 [⠢] Compiling 36 files with Solc 0.8.26 [⠆] Solc 0.8.26 finished in 1.06s Compiler run successful! 

And finally the files.

Made edits after comments below.

#!/bin/sh set +x set +e . .env echo "Running flash loan simulation" echo "PRIVATE_KEY: $PRIVATE_KEY" echo "SEPOLIA_RPC_URL $SEPOLIA_RPC_URL" echo "line 9" cat .env 

I have now set the .env permissions to 777 and both files are in the same folder.

$ ls -la total 68 drwxrwxr-x 9 myuser myuser 4096 Oct 7 12:09 . drwxrwxr-x 7 myuser myuser 4096 Oct 4 13:39 .. -rwxrwxrwx 1 myuser myuser 195 Oct 6 16:37 .env -rwxrwxr-x 1 myuser myuser 163 Oct 7 12:26 run.sh 

Running the script gives an error.

$ ./run.sh ./run.sh: 4: .: .env: not found 

Update round 2.

#!/bin/sh set +x set +e #. .env -->.: .env: not found #..env -->..env: not found #. ./env -->cannot open ./env: No such file echo "Running flash loan simulation" echo "PRIVATE_KEY: $PRIVATE_KEY" echo "SEPOLIA_RPC_URL $SEPOLIA_RPC_URL" echo "line 9" cat .env
