This env file content is,

export environment=dev

How can i read this env file and get the value "dev" to a variable in the upstart script?

Answer 1

Do you mean to "source" the content?

# cat foo
bar=VALUE
# source foo
# echo $bar
VALUE

It 'source' the file as a shell script in the current script scope. You can use "." in place of "source" (. foo)
