bash script someone may find useful

[Primefalcon]

I download my podcasts that I listen to using gpodder, but really you could modify the script for whatever... it is all just basic bash after all...

what it does is simply converts the episodes to a format rockbox can read and syns them onto or off the the ipod nano... feel free to take and modify and post back if you add a cool stuff

Code: [Select]

#!/bin/bash

iPodMount="ipod mount point"; #change this to your ipod mount point
gPodderFolder="$HOME/gpodder-downloads"; #change this to your podcast directory

convertEp() {
	if [ ! -d "$gPodderFolder/$1/$Rockbox" ]; then mkdir "$gPodderFolder/$1/$Rockbox"; fi
	cd "$HOME/Music/gpodder-downloads/$1"

#	lets convert all the video files into a format rockbox can play
	for f1 in *.mp4; do
		f2="${f1%.mp4}.mpeg"
		
		if [ ! -f "Rockbox/$f2" ]; then 
			avconv -i "$f1" -r 20 -s 176x100 -vcodec mpeg1video -b 250k -ab 92k -ac 2 -ar 44100 -acodec libmp3lame "Rockbox/${f1%.mp4}.mpeg" 2> /dev/null
		fi
	done

#	here we are just going to delete rockbox files that have been removed from gpodder
#	I dont need to bother about ogg files since rockbox can read those as downloaded
	cd "$HOME/Music/gpodder-downloads/$1/Rockbox"
	for rockfile in *.mpeg; do
		originalFileName="${rockfile%.mpeg}.mp4"
		if [ ! -f "$HOME/Music/gpodder-downloads/$1/$originalFileName" ]; then 
			rm -v "$rockfile" 2> /dev/null;
		fi
	done
}

syncEp() {
	if [ ! -d "$iPodMount/$1" ]; then mkdir "$iPodMount/$1"; fi


#	Lets check both video and audio to see if there are any new files to transfer to ipod

#	first the video
	if [ $2 == 'video' ]; then 
		cd "$gPodderFolder/$1/Rockbox";
		for rockfile in *.mpeg; do
			if [ ! -f "$iPodMount/$1/$rockfile" ]; then
					cp -v "$rockfile" "$iPodMount/$1/$rockfile" 2> /dev/null; 
			fi
		done
	fi

#	now for the audio	
	if [ $2 == 'audio' ]; then 
		cd "$gPodderFolder/$1";
		for rockfile in *.ogg; do
			if [ ! -f "$iPodMount/$1/$rockfile" ]; then
				if [ $rockfile != '*.ogg' ]; then cp -v "$rockfile" "$iPodMount/$1/$rockfile" 2> /dev/null; fi
			fi
		done
	fi

#	now that we've transferred over new files.... lets see if we can dump any from the ipod
#	also we'll get rid of any unused folers, will make it easier to see where eps are on the ipod

#	first the video
	if [ $2 == 'video' ]; then 
		cd "$iPodMount/$1";
		for rockfile in *.mpeg; do
			if [ ! -f "$gPodderFolder/$1/Rockbox/$rockfile" ]; then rm -vvv $rockfile 2> /dev/null; fi
		done
		rmdir "$iPodMount/$1" 2> /dev/null
	fi

#	now the audio	
	if [ $2 == 'audio' ]; then 
		cd "$iPodMount/$1";
		for rockfile in *.ogg; do
			if [ ! -f "$gPodderFolder/$1/$rockfile" ]; then rm -vvv $rockfile 2> /dev/null; fi
		done
		rmdir "$iPodMount/$1" 2> /dev/null
	fi
	
}

# if I just want to convert without touching the ipod (it might not be plugged in)
# so I'll type in at the terminal  (without quotes) "scriptName both"
if [ $1 == convert ]; then
	convertEp 'folder 1'
	convertEp 'folder 2'
        #and so on......
fi

# if I want to just sync files to the ipod that are currently
# in a format that the ipod can play without doing any converting
# since I might be in a rush and converting takes time
# so I'll type in at the terminal  (without quotes) "scriptName both"
if [ $1 == sync ]; then
	syncEp 'folder 1'
	syncEp 'folder 2'
        #and so on......
fi

# sometimes I might just want it to do both....
# so I'll type in at the terminal  (without quotes) "scriptName both"
if [ $1 == both ]; then
	convertEp 'folder 1'
	convertEp 'folder 2'
        #and so on......
	
	syncEp 'folder 1'
	syncEp 'folder 2'
        #and so on......
fi

Thanks, but this will get lost on the forums.  The wiki might be a better place for it.
