I can't find any > description in the changelog.) This was just something that I caught when I ran the test on my system. Where 'ls -ln' was not exactly the same as the output of 'ar -v'. I figured I would hard format the ls output to help. Obviously, if 'ar' decides to change its' format, then another failure will arise....which I suppose would need code to handle slight changes in formatting. :/ > > So, it was working before when it was originally written that "ar -s" > can restore the file size to that before the strip run?
