# This script send a text sms at the command line by creating
# a sms file in the outgoing queue.

# $1 is the destination phone number.
# $2 is the message text.
# If you leave $2 or both empty, the script will ask you.
# If you give more than 2 arguments, last is taken as a text and
# all other are taken as destination numbers.
# If a destination is asked, you can type multiple numbers
# delimited with spaces.

# Keys for example: "password" and "keke":
# KEYS="5f4dcc3b5aa765d61d8327deb882cf99 4a5ea11b030ec1cfbc8b9947fdf2c872 "

KEYS=""

# When creating keys, remember to use -n for echo:
# echo -n "key" | md5sum
