# Config variable for time logging (adds datetime infront of each entry)
timeLogged=false

# Slack webhook URL (only used on publish)

# Name
userName="Micha"

# Disallow a third parameter
if [ $# -gt 2 ]; then
    echo "Only two parameters are allowed. The second parameter should be in quotes."
    exit 1

case $1 in
    log)
        # Save the second input in a file
