YouTubeMonitorAndUpload

YouTubeMonitor.sh

#!/bin/sh
# Uses 'inoticoming' to efficiently monitor a directory and call an upload script.
#
# Usage:
# Remember to set the variables at the top of the script files.
# Can be run directly or at startup by adding lines to /etc/rc.local (Debian) example:
# sudo -b -u www-data /path/to/YouTubeMonitor.sh MONITOR_DIR COMPLETE_DIR [PLAYLIST_ID]
# Add one monitor line per directory/playlist.
# Now simply drop files into the monitored directory and they will be uploaded, named, tagged and playlisted.
#
# MONITOR_DIR might be an ftp, webdav or any directory.
#
# Depends on:
# - http://code.google.com/p/youtube-upload/ (download)
# - python-gdata (apt-get install)
# - inoticoming (apt-get install)
# - YouTubeUpload.sh (supplied)

## Set these variables.

Hi tokland,

Thanks for the review.
A benefit from the added overhead of using gist is that the end user can git clone the public url to their install dir and then commit local changes such as the variable settings. Any public improvements in the script can simply be verified and pulled into the installed clone, works like a charm.

The hard coded UID is required in the intended setup, the script interacts with webdav directories. I need to ensure that the www-data user is used for any and all script runs. The end user can disable the code block as suggested in the comments.

I use log this way for scripts that are meant to run unattended.
How would you use the log()? I guess this could provide a central place to change the log type?

I'm not a fan of set -e and agree with this http://mywiki.wooledge.org/BashPitfalls.
Instead I find myself using extra logging and error checking.

Fair enough, except for the prevention with "set -e":

http://mywiki.wooledge.org/BashPitfalls
"Some people also like to enable set -e to make their scripts abort on any command that returns non-zero, but this can be rather tricky to use correctly (since many common commands may return a non-zero for a warning condition, which you may not want to treat as fatal)."

This seems a pretty weak argument to me. It's like saying "this mechanism will fail on 1% of the cases, so let's not use it at all" :-) yeah, I know, false sense of security is also dangeous, but still...

You can have the best of two worlds: set -e + check the return of commands.

I saw that there is no real Google Drive Sync for linux (except proprietary) , I really need to sync a folder. I installed and configured rclone, and I was wondering if I can use inoticoming to trigger sync events.
I already use inoticoming to print (lpr) Pdf files, that my wife needs for her business. She saves them as pdf in a watched folder, and that triggers the print command.
^Nice Code !
