entrypoint.sh - line 9: syntax error: unexpected "("

Question

I am trying to run the following script from docker (based on alpine image)

#!/bin/sh

echo "test"

export USERNAME="AQICAHj456mvH8iSJofL46Xtr7KP6Ng3Vn5k6BpZbkAAAAZTBjBgkqhkiG9w0BBwagVjBUAgEAME8GCSqGSIb3DQEHATAeBglghkgBZQMEAS4wEQQMwCm8C+wSLRm/+sSuAgEQgCJHCFbrIwCQuH0x2iGp13j9SuxMtfrcE6c4SmrHRVkkX24f"
export AWS_REGION="us-east-1"
echo "$AWS_REGION"

decrypt=$(aws kms decrypt --ciphertext-blob fileb://<(echo "$USERNAME" | base64 -d))
export $key="$(echo $decrypt | jq .Plaintext -r | base64 -d)"

exec "$@"

I am getting the below output

test
us-east-1
/bin/entrypoint.sh: line 9: syntax error: unexpected "("

I am not sure how to resolve this syntax error. Any help is appreciated.

When I use `#!/bin/bash` I am getting this error `[FATAL tini (6)] exec /bin/entrypoint.sh failed: No such file or directory`. It is not able to recognize this as shell script — fledgling, Feb 27 '20 at 01:02
You probably have CRLF line endings, fix that with `dos2unix`. — Barmar, Feb 27 '20 at 01:03

tried doing `sed -e ':a' -e 'N' -e '$!ba' -e 's/\n/ /g' entrypoint.sh` on mac and pasted the text in the `entrypoint.sh` file. It did not work — fledgling, Feb 27 '20 at 01:13
I am still getting the same error. `#!/bin/sh` worked until halfway. Also wanted to remind this is alpine image — fledgling, Feb 27 '20 at 01:19
Please make up your mind: Do you want to use `sh`, or do you want to use `bash`? It doesn't make sense to discuss a program, if you don't have settled which language to use. — user1934428, Feb 27 '20 at 10:09

<(...) is a bash extension, it's not available in /bin/sh. You don't need it for your script, you should be using $(...) there.

decrypt=$(aws kms decrypt --ciphertext-blob fileb://$(echo "$USERNAME" | base64 -d))

Now it tried to do something. I am getting an error `'utf8' codec can't decode byte 0xf8 in position 12: invalid start byte` – fledgling Feb 27 '20 at 01:35

That's a Python error coming from `kms decrypt`, nothing to do with bash. Google it. – Barmar Feb 27 '20 at 01:40
