Brèves Linux

Après avoir vu l'effet sympathique, légérement différent du mien, des miniatures des screenshots de WindowsSucks sur ubuntuforums.org, j'ai décidé de l'ajouter à mon script.

Je vous propose donc une seconde version de mon script où j'en ai profité pour améliorer le traitement des options (le second effet pouvant être choisi ainsi).

#!/bin/bash
# Screenshot Script
# Author : Hells_Dark
# Homepage : http://breves.hellsdark.homelinux.net
# Required :
# scrot
# imagemagick
#
# Usage : shot [ Options ... ] [legend]
#
# Options :
#         -d      Set the destination directory to 
#         -l                 Thumbnail with legend
#         -w          Set the thumbnail width to 
#         -t           Define the thumbnail effect to  (1, 2 or 3)
#         -s time            Set the delay before shot to  (seconds)

#
# Usage Example :  shot -l -w300 -t2 -s3 "Awesome !"
