# allows you to have empty lines for better readability
eval $(cat .env | sed 's/^/export /')
# Here is another sed solution, which does not run eval or require ruby:
source <(sed -E -n 's/[^#]+/export &/ p' ~/.env)
# .env contents
A=1
#B=2
# sample run
$ sed -E -n 's/[^#]+/export &/ p' ~/.env
export A=1
#export B=2
export $(xargs < .env)
# Explanation
# When we have a .env file like this:
key=val
foo=bar# export.sh .env
set -a # export all variables created next
source $1
set +a # stop exporting
# To ignore lines that start with #, use this (thanks to Pete's comment):
export $(grep -v '^#' .env | xargs)
# And if you want to unset all of the variables defined in the file, use this:
unset $(grep -v '^#' .env | sed -E 's/(.*)=.*/\1/' | xargs)
# convenience command to prepend export to the beginning of
awk '{print "export " $0}' envfile
