Rewrote my “Free Ice Cream” script in bash because I needed to be able to flexibly send emails without going through 20 UAC prompts due to restrictions and how many people are scared of PowerShell.
Below is my new implementation, instead of relying on Outlook (like before), this version is platform independent and will work on any OS with any Mail Client like Thunderbird or Gmail.
rawurlencode() {
local string="${1}"
local strlen=${#string}
local encoded=""
local pos c o
for (( pos=0 ; pos<strlen ; pos++ )); do
c=${string:$pos:1}
case "$c" in
[-_.~a-zA-Z0-9] ) o="${c}" ;;
* ) printf -v o '%%%02x' "'$c"
esac
encoded+="${o}"
done
echo "${encoded}"
}
function generateParticipants() {
PARTICIPANT_LIST=("$@")
PARTICIPANT_STRING_TO_RETURN=""
SEPARATOR=";"
for PARTICIPANT in "${PARTICIPANT_LIST[@]}";
do
PARTICIPANT_STRING_TO_RETURN+="$PARTICIPANT"
PARTICIPANT_STRING_TO_RETURN+="$SEPARATOR"
done
echo "$PARTICIPANT_STRING_TO_RETURN"
}
function createEmail() {
SUBJECT="$1" # Save first argument in a variable
shift
BODY="$1" # Save second argument in a variable
shift # Shift all arguments to the left (original $1 gets lost)
TO_ARRAY=("$@")
TO=$(generateParticipants "${TO_ARRAY[@]}")
SUBJECT_ENCODED=$(rawurlencode "$SUBJECT")
BODY_ENCODED=$(rawurlencode "$BODY")
MESSAGE_OBJECT="mailto:$TO&subject=$SUBJECT_ENCODED&body=$BODY_ENCODED"
echo "########################"
echo "#### EMAIL PREVIEW: ####"
echo "########################"
echo ""
echo "To: $TO"
echo "Subject: $SUBJECT"
echo "Body: $BODY"
echo ""
echo "Sending to Email Client..."
echo ""
echo start "" "$MESSAGE_OBJECT"
start "" "$MESSAGE_OBJECT"
}
EMAIL_SUBJECT="Free Ice Cream!"
EMAIL_BODY="I'm Buying."
PARTICIPANT_LIST+=("person1@company.com")
PARTICIPANT_LIST+=("person2@company.com")
PARTICIPANT_LIST+=("person3@company.com")
createEmail "$EMAIL_SUBJECT" "$EMAIL_BODY" "${PARTICIPANT_LIST[@]}"
