this is the final version that im using, seems to work for all situations

Thanks @MansourM !

Looks great, but it doesn't work if the .env file contains only 1 row (just one without br)

how do you use it?
you get any errors?
btw u need to comment or remove this line as you don't have the log function
log "Reading $filePath"
I needed this and after reading the above realized none of the solutions quite worked for my .env file on a Mac... so I modified what @shadiabuhilal into this (which I put into a file called "readenv")
# quick bash function to read .env file
# use it via:
# source readenv
# readenv
#
# or
#
# readenv <filename>
#
# modified from https://gist.github.com/mihow/9c7f559807069a03e302605691f85572
# fixed for whitespace issues, posix compliance (e.g. \t on mac means t)
#
# NOT a standalone script as when used as a standalone script, it'll read in the ENV variables into a sub-process, not the
# calling process
readenv() {
local filePath="${1:-.env}"
if [ ! -f "$filePath" ]; then
# silently be done
# put some error / echo if you prefer non-silent errors
return 0
fi
# echo "Reading $filePath"
while read -r line; do
if [[ "$line" =~ ^\s*#.*$ || -z "$line" ]]; then
continue
fi
# Split the line into key and value. Trim whitespace on either side.
key=$(echo "$line" | cut -d '=' -f 1 | sed -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//')
value=$(echo "$line" | cut -d '=' -f 2- | sed -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//')
# Leaving the below here... normally this works, but if you have something like
# FOO=" string with leading and trailing "
# then the leading / trailing spaces are deleted. FOO="a word", FOO='a word', and FOO=a word all generally work
# so leave the quotes
# Remove single quotes, double quotes, and leading/trailing spaces from the value
# value=$(echo "$value" | sed -e "s/^'//" -e "s/'$//" -e 's/^"//' -e 's/"$//' -e 's/^[[:space:]]*//;s/[[:space:]]*$//')
# Export the key and value as environment variables
# echo "$key=$value"
export "$key=$value"
done < "$filePath"
}
Also - recommend to use [[:space:]] rather than \s or [ \t] --- on Macs, \s isn't space, and \t isn't TAB but t. Yay standardization!
This is what I use:
# shellcheck disable=SC2046
[ -f .env ] && export $(grep -v '^#' .env | xargs)
No need to do a double negation with [ ! -f .env ] ||
when you can do [ -f .env ] &&
@bfontaine thanks, worked like a charm.
@abhidp it seems, that it works well - even with comments in
.env
! :D (cc: @muthugit)
