String-concatenation in bash leads to weird url

Question

when using the following command:
url="http://localhost:8086/writedb=speedtest&u=${INFLUXDB_USERNAME}&p=${INFLUXDB_PASSWORD}" and then echo "${url}"

Before I use source .env to load my variables from the file:

INFLUXDB_USERNAME=admin
INFLUXDB_PASSWORD=admin

Leads to:

&p=adminocalhost:8086/write?db=speedtest&u=admin
curl: (3) Illegal characters found in URL

It looks like your .env file has [DOS/Windows line endings](https://stackoverflow.com/questions/39527571/are-shell-scripts-sensitive-to-encoding-and-line-endings), which cause all sorts of trouble unless they're converted to unix style. — Gordon Davisson, Apr 12 '22 at 16:56

Solution: instead of source .env

source <(sed $'s/\r$//' .env)

If your .env file was created in Windows you can convert it using

dos2unix .env
source .env
