Request for Comments: I know ls already has very many options, but I find it indispensable having the file-size field formatted with a thousands separator (e.g. a file size of 1234567890 prints as "1,234,567,890"). I'm working with larger and larger files all the time, and now that most OS's are supporting 64-bit file addressing, files well over 2GB are becoming more common. The --human-readable option addresses this issue in a very nice and well-implemented fashion, but I find that my brain visually prefers comma-separated large numbers to the --human-readable formatting style, especially in long columns. I downloaded the fileutils-4.0l distribution and have made all the code changes to implement this feature. I made the option '-K' or '--kilo-separator'. Output below shows what "ls -lK" looks like, with "ls -l" and "ls -lh" for comparison. Note that the -K option automatically widens the file size field from 8 to 13, which allows files up to 9,999,999,999 bytes to align properly in columns. Any comments or feedback? Do you like this feature, or find it useful? John W.
