illumos being the only one I could find where when compiled for /usr/xpg4/bin/du rather than /usr/bin/du, a space is used: https://github.com/illumos/illumos-gate/blob/1979231e1e29c981e5d1e6cee60f2db46d052b00/usr/src/cmd/du/du.c#L72-L81 A hunch I have is the literal tab degrading into a space on POSIX side of things. Desired Action: Given how widespread tab separation is: Either changing the specified format of du(1), line 93067 on Draft 4.1, from "%d %s\n" to "%d\t%s\n" or clarifying that either space or tab can be used as separator. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2024-04-07 01:48 lanodan New Issue 2024-04-07 01:48 lanodan Name => Haelwenn Monnier 2024-04-07 01:48 lanodan Section => du 2024-04-07 01:48 lanodan Page Number => 2808 2024-04-07 01:48 lanodan Line Number => 93064-93067 ======================================================================
