Bash script: sync a USB drive

If you want to sync certain directories from your computer to a removable drive (USB flash drive or external hard drive), use this Bash script as a starting point and modify it:

#!/bin/bash

# set variable for USB drive
USBDRIVE="/media/USBFLASH/"
# set variable for podcast list file
PODCASTLIST="${HOME}/iPodderData/favorites.txt"
# set variable for temp directory
TEMPDIR="${HOME}/temp/"
# set variable for scripts directory
SCRIPTSDIR="${HOME}/auto/"
# set variable for encrypted file
CRYPTFILE="${USBDRIVE}tools/truecrypt/alpha"
# set variable for local directory to backup USB drive to
USBBACKUPDIR="${HOME}/.USBFLASH/"
# set variable for files directory on USBDRIVE
FILESDIR="${USBDRIVE}files/nx6125/"

# sync PODCASTLIST to USB drive
# rsync --verbose --recursive --update --delete --progress $PODCASTLIST $FILESDIR
# sync TEMPDIR to USB drive
rsync --verbose --recursive --update --delete --progress $TEMPDIR ${FILESDIR}temp
# sync SCRIPTSDIR to USB drive
rsync --verbose --recursive --update --delete --progress $SCRIPTSDIR ${FILESDIR}auto

# sync USBDRIVE to USBBACKUPDIR
rsync --verbose --recursive --update --delete --progress $USBDRIVE $USBBACKUPDIR

# unmount USB drive if desired
echo "Unmount? y/n"
read ANSWER
if [ "$ANSWER" = "y" ]; then
sudo umount $USBDRIVE
echo "$USBDRIVE unmounted!"
else
echo "$USBDRIVE still mounted!"
fi

The difference between burritos, chimichangas, and enchiladas

I love Mexican food, but I'm embarrassed to admit that I always get confused between burritos, wet burritos, chimichangas, and enchiladas. Here are the descriptions, with the differences in bold and pictures following each description.

burrito
A flour tortilla wrapped around a filling (meat, beans, vegetables, etc)


wet burrito
A burrito that's covered in red chili sauce and cheese. Because of the sauce covering, it looks like an enchilada, but it's made with a flour tortilla, whereas the enchilada is made with a corn tortilla.


chimichanga
A burrito that's deep-fried. Sometimes covered with cheese or another topping.


enchilada
A corn tortilla wrapped around a filling, covered with chili pepper sauce

Considering retiring this blog

I'm seriously considering retiring this blog. When I started it in 2008, it was a place for me to share thoughts and links on a variety of topics. For at least the last year, however, it's just been a place where I re-post book reviews from Goodreads.

You can see all my book reviews on my Goodreads profile, and subscribe to my Goodreads RSS feed to be notified of new reviews. I also intend to keep blogging about WordPress, web design, and web-related topics on my OptimWise blog, which also has an RSS feed.

Would you miss this blog if I discontinued it? Please leave a comment.
