Yes that is inconsistent. Interestingly the POSIX defined expand and unexpand are inconsistent in relation to this to start with. unexpand only processes leading blanks by default, but expand processes all blanks by default. So unexpand needs the -a option to process all blanks, and expand needs the -i, --initial option to process only leading blanks. Given the above you might think that the --first-only option to unexpand is redundant. However -a is implied by -t (as per POSIX), therefore to really limit to initial blanks, you need this option. So as for naming. I agree that --first-only is inconsistent. It's also a bit ambiguous. Does it mean only the first tab is written, or all leading blanks are processed. Now deprecating --first-only for the more consistent --initial has some cost. For example it would break part of my FSlint program: http://code.google.com/p/fslint/source/browse/trunk/fslint/supprt/rmlint/= fix_ws.sh Also, I see busybox copied --first-only into its unexpand implementation. But I guess to be forward looking --first-only should be deprecated in favor of --initial? thanks, P=C3=A1draig.

Hi, bug-coreutils@HIDDEN -
Not quite a bug, but why does the same option, essentially, have two very
different names in the 'expand' and 'unexpand' utilities?
This is confusing and hampers convenient usage.
I am referring to* --initial* in the one case and* --first-only* in the
other.
See below.
Or what am I missing?
Thanks.
