12 7:44 gifmerge -h gifmerge -h shows you the options of and the help screen for the gifmerge program. It merges 2 or more .gif files to create a single animated gif file. 13 7:46 gifmerge -10 -l0 zeb*.gif > twirl.gif I merged all of my zebra files (the input to gifmerge) and gifmerge produced as output the file twirl.gif, which consists of all the input files in an animation, alphabetical animation of the original files, with 0.1 second between each frame of the animation. Q1. Login to your chaos account, type gifmerge -h, read about the gifmerge command. What does the -l0 do in the command: gifmerge -10 -l0 zeb*.gif > twirl.gif <42 chaos:~/web/gifs >ls zeb* zeb1.gif* zeb3.gif* zeb5.gif* zeb7.gif* zeb9.gif* zeb2.gif* zeb4.gif* zeb6.gif* zeb8.gif* Q2. How many frames does the twirl.gif animation have? 14 7:46 ls -l *.gif 15 7:47 chmod 644 twirl.gif 23 8:27 gifmerge -15 glow*.gif > twirlButton.gif 24 8:27 chmod 644 twirlButton.gif Q3. What is the input to this execution of the gifmerge program? Shown below is the list of files that begin with "glow" and match the pattern glow* as the file name. <49 chaos:~/web/gifs >ls glow* glow1.gif glow4.gif glow7.gif glow9a.gif glow9d.gif glow2.gif glow5.gif glow8.gif glow9b.gif glow3.gif glow6.gif glow9.gif glow9c.gif Q4. How long will it take the twirlButton.gif animation to run through all of the frames once? Q5. What command would you use to merge all files that begin with the upper-case letters J and E ("JE") and end with the suffix .gif to create the animated gif file named alaska.gif, with each frame shown for .3 second, and the entire animation running through 10 times (instead of once and instead of infinite)? gifmerge -h output on your screen or your partners screen will help you answer this question. Q6. The file named mystery.gif is an animated gif file. http://www.cns.uni.edu/~jacobson/gifMystery/mystery.gif is the URL. mystery.gif was created by using the gifmerge command on the chaos computer. Make an educated guess as to what the gifmerge command was that created mystery.gif and explain your reasoning for each portion of the command. Make an educated guess as to how many files were input to the command and what those files probably were, if you assume that the input came from the gifMystery folder.
