 What do you think?

 I agree, the option has been added to df in 1996, and declared
 obsolescent in 2001, so the period since the latter is twice as
 long as the active use.

 And it's very easy to s/--megabytes/-BM/ ...
 
 More important than 2001 is the year in which we removed
 the reference from the man page and from --help: 2007

You're right. Then what about a deprecation warning and removing
the long option in 2013?

P.S. Make syntax-check doesn't find the offender against
sc_error_message_uppercase for the Warning: message when
(mount_list == NULL) in df.c

Have a nice day,
Berny

Thanks.  Applied with log tweaks (e.g., s/W/w/ in summary, removed
each * src/df.c after the first -- * introduces a new file).

 I think the general idea is that -k was a mistake, but
 it's standardized, and that we don't want to have
 options -m, -g, -t, -p, -e, -z, -y for the other sizes
 (among other things -t is already taken).  -m is there
 only for BSD compatibility but we don't want to publicize
 it and we may want to take it back at some point.

Wouldn't it then be consequent to remove the long option --megabyte?
(It's sister --kilobyte has been removed by v6.9-151-g1e07a21
in 2007.)

Have a nice day,
Berny

Yes, that does make sense.

Hi Berny,

I like the idea, but wonder if an abrupt removal would break old scripts.
For du, we made its --megabytes option issue a warning first, and removed
it altogether a year or two later.

However, I'm tempted to remove it directly this time, since it's been
undocumented for a while:

  5 years in df.1 and df --help: COREUTILS-6_9-151-g1e07a21
  11 years in coreutils.texi: FILEUTILS-4_1_4-28-gf5bf6fe

What do you think?

2012-07-04 Thread Andreas Jaeger
df -k and df -m both work but only df -k is mentioned as part of df --
help. So, the omission to document -m is IMO a bug.

A second issue:
Since df supports -k and -m, shouldn't if support -g (as synoym for --
block-size=1M as well?

Btw. df --version outputs:
df (GNU coreutils) 8.16
