The envrun
command allows running any command with default environment
variables taken from a file, copying its standard error and standard output to
its own standard error and standard output.
Variables already present in the environment override the one in the file.
The command may have arguments, and it will be looked up in the $PATH
if its
name does not contain a /
.
Install from source, using a Go SDK: go install github.com/fgm/envrun@latest

file, and many IDEs
support that feature in run configurations.
This command is provided for situations outside an IDE (e.g. CI/CD) and where the program to be run does not include this feature.
