Speedtest Runner and Parser

speedit.sh

#! /bin/bash

# This is a script to run the speedtest-cli command, you'll need to make sure it's
# installed and that you know the location of it.
# The speedtest-cli can be found at https://github.com/sivel/speedtest-cli
# Or, you can just use the following:
# $ curl -Lo speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest_cli.py
# $ chmod +x speedtest-cli
# This file will need to be executable as well

# For ease of use, consider putting this in a Cron job, e.x. :
# */5 * * * * /Location/Of/Speedit/speedit.sh
# The above will run the speedtest every five minutes

# FILE is the location you'd like the CSV to be created in
FILE="/tmp/download_speeds.csv"

# SPEEDTEST is the location of the speedtest-cli executable
SPEEDTEST="/usr/local/bin/speedtest-cli"

# Right now, let's only worry about the Download speed.
DOWNLOAD_SPEED=$($SPEEDTEST --simple | grep "Download" | tr -s ':' | cut -d' ' -f2)

# If FILE cannot be found, let's make it and add the column titles to the top
if ! [ -f "$FILE" ]; then
    echo "timestamp,download_speed" >> "$FILE";
fi

# Append the date and DOWNLOAD_SPEED to the end of the CSV
echo $(date +%s)"," $DOWNLOAD_SPEED >> $FILE

# Uncomment the below to display notifications in notification center
# osascript -e "display notification \"$DOWNLOAD_SPEED\" with title \"Download Speed:\""
