 +Dont forget to give execution permission to the file! E.g: sudo chmod a+x /​usr/​bin/​folder-thumbnailer
 +
 +Note: imagemagick is a required dependency for this script.
 +
 +==== Customized Thumbnailer for text-based documents ====
 +A thumbnailer for text-based documents can be created using the convert function from the imagemagick package with the following thumbnailer file:
 +
 +<file txt /​usr/​share/​thumbnailers/​text.thumbnailer>​
 +[Thumbnailer Entry]
 +Version=1.0
 +Encoding=UTF-8
 +Type=X-Thumbnailer
 +Name=Text Thumbnailer
 +MimeType=text/​plain;​text/​html;​text/​css;​
 +Exec=/​usr/​local/​bin/​textthumb %s %i %o
 +</​file>​
 +
 +And supporting script:
 +
 +<file sh /​usr/​local/​bin/​textthumb>​
 +#!/bin/bash
 +iFile=$(<"​$2"​)
 +iChopped="​${iFile:​0:​1600}"​
 +unset iFile
 +echo "​${iChopped}"​ > tmp.txt
 +unset iChopped
 +convert -size 210x290 -background white -pointsize 5 -border 10x10 -bordercolor "#​CCC"​ caption:​@"​tmp.txt"​ "​$3"​
 +rm tmp.txt
 +</​file>​
 +
 +You can add additional mime types to the MimeType line of the thumbnailer file to support additional text-based document types.
