I have a .env file that contains information, to include environment variables. For example:
# comment
<mini script>
export NAME="John Doe"
export LOCATION="US"
export TZ_LOCAL="NY"
When ran, I am able to have these environment variables; however, when done, a script runs to unset
the environment variables.
This is the snippet that does such:
unset $(grep 'export' env | awk 'BEGIN { FS = "=" }; { print $1 }' | awk 'BEGIN { FS = " " }; { print $2 }')
This seems a bit much. Is there a simpler way to get the variable name after export and stop at the equal sign?
This snippet works, but seems like there should be a much simpler way than my snippet with multiple pipes.
Use space and =
as input field separator:
unset $(awk -F '[ =]' '/^export .*=/{print $2}' env)
