I was just searching the archives and saw someone recommend installing GNU fileutils. One word of caution: I had some very strange problems on standard software installers when I upgraded to GNU's versions of common file manipulators. du in particular. Appears that the output of the GNU version changes a column title from "Avail" to "Available", or something like that.
I tried to run the 10.0.4 update shortly after compiling and installing these utils (couldn't stand not having human-readable file sizes with ls), and got errors from the updater saying that I didn't have enough disk space. But I had 25 GB available, didn't make sense. I dug into the install script (mercifully written in perl) and found a regex pattern parsing the output of du. Changing the pattern made the installer run, but I was sufficiently spooked and restored an older copy. Or has this been fixed? Best Wishes, Troy Davis
