On 1998-06-29. But the only use of BLOCKSIZE before then was BLOCKSIZE='HUMAN' and BLOCKSIZE='SI'; no other values were supported, and that old usage (which itself was introduced in two changes: 1996-01-20 and 1997-11-30) wasn't described in the texinfo documention and wasn't consistent with the --block-size long option. As the 1998 change caused the environment variable to have the same interpretation as the "--block-size" long option, I thought it more consistent at the time to spell the environment variable "BLOCK_SIZE" rather than "BLOCKSIZE". > It seems to me like it would be reasonable to use $BLOCKSIZE if > $BLOCK_SIZE isn't set, simply because it's widely used elsewhere. Something like that sounds reasonable, except what is BLOCKSIZE supposed to mean when it's widely used elsewhere? Do you have a specification somewhere? I couldn't find one. I did notice behavior quirks, though. For example: openbsd-3.2$ BLOCKSIZE=1048576 df . Filesystem 1048576-blocks Used Avail Capacity Mounted on sic:/export/ford 17239 9695 7371 57% /whatever coreutils-5.2.0$ BLOCK_SIZE=1048576 df . Filesystem 1M-blocks Used Available Use% Mounted on sic:/export/ford 17240 9696 7372 57% /whatever Note that the BSD "df" says "1048576-blocks" whereas the coreutils "df" says "1M-blocks". (There are some rounding inconsistencies, too.) While we're on the subject, it appears to me that there is a bug in how du/df/ls etc. treat invalid environment-value settings. For example: $ ls -ld drwxr-xr-x 40 eggert eggert 4096 2004-02-22 20:17 . $ BLOCK_SIZE=ridiculous ls -ld drwxr-xr-x 40 eggert eggert 4 2004-02-22 20:17 . It seems to me that "ls" etc. should ignore ridiculous settings like that, instead of having them be equivalent to BLOCK_SIZE=1024. Does that sound right to you? If so, I can prepare a patch. (But this might be related to the issue of what BLOCKSIZE actually means on those other platforms.) _______________________________________________ Bug-coreutils mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/bug-coreutils
