Tool for installing PQ

As a computer nerd, I like to find solutions that automize repetitive tasks. Therefore, I've written a little bash script that unzips pocket query files directly to the gps (or sd card), deletes the associated waypoints file (optional), and corrects the mystery/unknown cache icons (latest addition).

 

I thought I'd share my program in the hopes that it will help some of you out, and in hopes that some of you can help me optimize the script and make it more universal.

 

Challenge #1: identifying pocket query files. My most commonly used pocket queries begin with the number 1, but it seems that newer queries now begin with the number 2. Therefore, to distinguish PQ gpx files from non PQ files, I'd like to be able to identify all files that begin with a number. You'll see where this applies in the code below.

 

The program:

#!/bin/bash

#This script will unzip pocket queries and place the gpx files on the SD card of the gps.

cd ~/Desktop/export/GPX/
echo "Do you wish to clear all Pocket Query files?"
echo "Type yes or no."
read rem

if [ "$rem" = "yes" ];
then
rm /Volumes/GPS\ SD\ CARD/Garmin/gpx/1*.gpx 
fi

for i in *.zip
do unzip -o $i -d /Volumes/GPS\ SD\ CARD/Garmin/gpx
done

rm *.zip

echo Do you want to keep the waypoint files? 
echo Type \"yes\" or \"no\".
read wpt

if [ "$wpt" = "no" ];
then
echo "Removing waypoints files."
rm /Volumes/GPS\ SD\ CARD/Garmin/gpx/*wpts.gpx
fi

echo Do you need to correct Mystery caches?
echo Type \"yes\" or \"no\".
read myst

if [ "$myst" = "yes"];
then
cd /Volumes/GPS\ SD\ CARD/Garmin/gpx/

for file in 1*.gpx
do echo fixing $file
sed -i.bak s/Mystery\ Cache/Unknown\ Cache/g $file
done

rm *.bak
fi

echo "Done!"

exit

Did you know that at the end of the PQ creation screen there's a tick box which says:

 

Include Pocket Query name in download file name

 

so I named all my scheduled Pocket Queries as "PQ 01", "PQ 02",... etc, then the .zip files are named randomnumber_PQ01.zip etc, and the gpx files within the zip are named randomnumber_PQ01.gpx and randomnumber_PQ01-wpts.gpx.

(note if you have spaces in the Pocket Query name then the spaces will be removed from the filenames)

 

So if you name all your Pocket Queries with something identifiable and tick that box, identifying the pocket query files becomes easy.

 

Edit to add (in case there are any pedants watching), yes I know it's not actually a random number, but for the purposes of this exercise it may as well be.

I've thought about doing that. I've got a fair number of pocket queries, but it wouldn't be hard to rename them.

 

Also... one thing I forgot to mention, but in order for the sed program to work properly to fix the mystery-unknown cache issue, the file names can't have any spaces or special characters in them.

[+MartyBartfast]

The can if you quote the filename, so

 

sed -i.bak s/Mystery\ Cache/Unknown\ Cache/g $file

 

becomes

sed -i.bak s/Mystery\ Cache/Unknown\ Cache/g "$file"

 

I would also quote the sed string, to avoid escaping the spaces as I think it make it more readable, but that's just a matter of preference:

sed -i.bak "s/Mystery Cache/Unknown Cache/g" "$file"

Thank you.

 

I also found the answer to my original problem: display only gpx files that begin with a number:

ls [0-9]*.gpx

 

I've updated my script with this and MartyBartfast's sugestion so that it should be universal to anybody's PQ naming scheme. Of course, you'll have to modify the directories to match your GPS.

 

#!/bin/bash

#This script will unzip pocket queries and place the gpx files on the SD card of the gps.


#cd ~/Desktop/export/GPX/ 

echo "Do you wish to clear all Pocket Query files?"
echo "Type yes or no."
read rem

if [ "$rem" = "yes" ];
then
rm /Volumes/GPS\ SD\ CARD/Garmin/gpx/[0-9]*.gpx
fi

for i in *.zip
do unzip -o $i -d /Volumes/GPS\ SD\ CARD/Garmin/gpx
done

rm *.zip

echo Do you want to keep the waypoint files? 
echo Type \"yes\" or \"no\".
read wpt

if [ "$wpt" = "no" ];
then
echo "Removing waypoints files."
rm /Volumes/GPS\ SD\ CARD/Garmin/gpx/*wpts.gpx
fi

echo Do you need to correct Mystery caches?
echo Type \"yes\" or \"no\".
read myst

if [ "$myst" = "yes" ];
then
cd /Volumes/GPS\ SD\ CARD/Garmin/GPX

for file in [0-9]*.gpx
do echo fixing $file
sed -i.bak "s/Mystery Cache/Unknown Cache/g" "$file"
done

rm *.bak
fi

echo "Done!"

exit

This is the latest iteration that I've been using. Includes some parallel processing to load multiple files on your device at once, because Garmin hasn't kept up with modern USB port speeds and a full PQ takes "a while" to transfer.

 

#!/bin/bash

#This script will unzip pocket queries and place the gpx files on the SD card of the gps.


#cd ~/Desktop/export/GPX/ 

echo "Do you wish to delete all Pocket Query files currently on the device?"
echo \"yes\" or \"no\"
read rem

echo Do you want to keep the waypoint files? 
echo \"yes\" or \"no\"
read wpt

echo Do you wish to delete the original .zip files?
echo \"yes\" or \"no\"
read delzip


if [ "$rem" = "yes" ];
then
echo Removing previously installed PQ files.
rm /Volumes/GPS\ SD\ CARD/Garmin/gpx/[0-9]*.gpx
fi

for i in *.zip
do unzip -o $i -d /Volumes/GPS\ SD\ CARD/Garmin/gpx &
done
wait

if [ "$delzip" = "yes" ]
then
echo Deleting downloaded .zip files.
rm *.zip
fi


if [ "$wpt" = "no" ];
then
echo "Removing waypoints files."
rm /Volumes/GPS\ SD\ CARD/Garmin/gpx/*wpts.gpx
fi

echo "Done!"

exit
