mac_wifi.sh

echo "start `date`"

# Get the directory of the currently running script
script_dir=$(dirname "$0")

# Change the working directory to the directory of the script
cd "$script_dir"

echo `pwd`

results="results.csv"
if [[ -f $results ]]; then
    echo "File exists."
else
    echo "File does not exist."
    touch $results
fi

# Now you're in the directory of the running script
# Get network name
wifiName=$(/usr/sbin/networksetup -getairportnetwork en0)
date=$(date +"%Y-%m-%d")
wifiName="${wifiName#"${wifiName%%[![:space:]]*}"}"
wifiName="${wifiName%"${wifiName##*[![:space:]]}"}"
out="$date;$wifiName"
#out="2024-04-24, Current Wi-Fi Network: Deputy_VN"
echo $out

if grep "$out" $results; then
    echo "Text found in the file."
else
    echo "Text not found in the file."
    echo $out >> $results
fi
