Save tracks on a USB stick so that they play in order on some inferior Pioneer Car Stereo equipment

First copy all contact to a temporary location ... let's say /var/tracks. Make sure all tracks are numbered in such a way that that they list in correct order numerically i.e. prefix with 01..02..//..10..11 etc

The destination location for this example is /media/stick/

find /var/tracks/  | sort -n  | while read fn; do cp --parents -f "$fn" /media/usb-stick/; sleep 1; done

Convert .mov file to h264 (mp4 container)

Useful for Canon EOS cameras to save space on storage.

avconv -nostdin -i inputfile.mov -c:v libx264 outputfile.mp4

Convert MTS to mkv and reduce scale

ffmpeg -nostdin -i  $fn -vf scale=1024:-1 ~/Videos/conv/$fn.mkv

or with deinterlacing

 ffmpeg -i 00168.MTS -s 1024x768 -vcodec libx264 -crf 20 -acodec ac3 -vf "yadif" /mnt/mp4vids/00168.mp4

Copy files found between two dates from a heirachical structure to a flat structure

find . -type f -newermt 2016-08-07 ! -newermt 2016-08-30 -printf %p\|%f\\n | while read names
do IFS='|' read var1 var2 <<< `echo $names`; rsync -Pva "$var1" root@remote.machine.com:"/var/path/$var2"; done
