I'm using 1.3.15-cygwin-1-3-15-1. "ls -l" and "ls -ln" takes almost the same amount of time. On a directory with 3 short text files, the difference, when I timed "ls -l" and "ls -b", is still considerable. fcarlo@ZEUS~ $ time ls -b a b test real 0m0.024s user 0m0.030s sys 0m0.015s fcarlo@ZEUS ~ $ time ls -l total 11 -rw-r--r-- 1 fcarlo None 5 Nov 19 13:58 a -rw-r--r-- 1 fcarlo None 5 Nov 19 13:58 b -rw-r--r-- 1 fcarlo None 8283 Nov 19 13:59 test real 0m1.819s user 0m0.030s sys 0m0.000s Best Regards, Carlo Florendo > > Carlo, > It would have been more helpful if you had provided your cygwin version, > but even without it I could venture a guess...
