That, however, is irrelevant - it changes the behaviour of the utility, and
that's it. :)
But OK, the locale thing convinced me; it'd be possible to make it work with
any locale, but only with a disproportional amount of work.
So, any objections to supplying it as DF()?

It is different as it only changes the default parameters for a program.
In your case you putting the output from df trough column and sed.
And in addtion the sed command is only useful with the english locale and not
any other like for example german http://nopaste.narf.at/show/24/

Yes as the alias only adds additional parameters.

Well, fwiw, grml already has such wrappers (this is one of the things that
make it appealing). For example, ls is by default aliased to:
ls='ls -b -CF --color=auto'
I don't see how this is any different.
But I'd be happy with DF() instead of df() if you really think modifying
ls(1) is OK but modifying df(1) isn't. :)

Hey there,
I've been asked to comment on this, so here goes:
I am firmly against adding a wrapper around something that works,
which requires a certain implementation of the given command and
only works in certain scenarios (e.g. in a certain locale). And
especially when its only purpose is to correct some cosmetic
issues (if you'd even call it an issue).
Feel free to add this to your .zshrc.local file. IMO, this issue
should be marked wont-fix for the reasons I gave earlier. (Unless,
of course, I'm out-voted by a large number of fellow grml-developers.)
Regards, Frank

So what about the aliases for grep, ls and dir? :)
Like I said, it only alters the behaviour of df in interactive shells.
Normally I'd agree with you, but given this constraint, I don't see the
problem.

DF() comes to mind as a cheap replacement. But I'd still prefer df()... Is
there an effortless way to poll users about it?

I like the idea but don't think changing behaviour of traditional
UNIX commands is a good idea. Though I'd ACK this function under a
different name, suggestions welcome. :)

Hi,
please consider including this in your zshrc:
function df() {
/bin/df -a --portability "$@" | column -t | sed
's/Mounted[[:space:]]*on/Mounted on/'
}
This makes df output a lot more readable by making sure that all information for
each filesystem is on a single line and still nicely tabulated.
Observe the difference between the old and new behaviour:

Including the -a (which causes "dummy" filesystems to be included) is useful
especially for chroots and vservers with bind mounted filesystems; if /etc/mtab
includes an entry where the device doesn't exist, df will by default skip that
entry in the output, which is the wrong thing to do for bind mounts. I don't
think there are so many actual dummy filesystems that their inclusion would
seriously clutter the output of df.
Placing this function in zshrc would ensure that it's only loaded for
interactive shells; thus it wouldn't interfere with scripts that attempt to
parse the output of df(1).
