Yeah....

<summary>The test script: Click to expand!</summary>
```
#!/bin/bash
connection_url="$1"
[[ ${connection_url} =~
([^:]*)://([^:@]*):?([^@]*)@?([^/:]*):?([0-9]*)/([^\?]*)\??(.*) ]] && \
detected_backend=${BASH_REMATCH[1]} &&
detected_user=${BASH_REMATCH[2]} &&
detected_password=${BASH_REMATCH[3]} &&
detected_host=${BASH_REMATCH[4]} &&
detected_port=${BASH_REMATCH[5]} &&
detected_schem=${BASH_REMATCH[6]} &&
detected_params=${BASH_REMATCH[7]} &&
echo "Backend='${detected_backend}'" &&
echo "User='${detected_user}'" &&
echo "Password='${detected_password}'" &&
echo "Host='${detected_host}'" &&
echo "Pprt='${detected_port}'" &&
echo "Schema='${detected_schema}'" &&
echo "Params='${detected_params}'"
```
</details>
And the result:
```
./test.bash "redis://redis-analytics-airflow.signal:6379/1"
Backend='redis'
User='redis-analytics-airflow.signal'
Password='6379'
Host=''
Pprt=''
Schema=''
Params=''
```
This is the embodiment of the famous ancient Chinese proverb (wisdom of the
ancients):
> If you have a problem, introduce regexp - you will have two problems.
I will fix it without using regexps.
