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


  • envrun foo: run foo with the environment defaults loaded from .env if it exists, or fail if it cannot be read.
  • envrun -f .env.demo env: run the env command with the environment defaults loaded from .env.demo or fail if it cannot be read
Exit status
  • If the command exits, envrun will return its exit status
  • If the command is killed, envrun will return exit status 1

Why ?

Many programs support reading their environment from a .env 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.
