But still the same question: how many users would like to see them per default, and how many do not? I would not like to argue for something like a ~/.dfrc, but it seems there are a lot of different flavors of wishes out there. Yet leaving the default seems to be a wise choice to me. FWIW: df has the -x option, but if someone would use it in an alias like "df -x sqashfs", then there's currently no chance to override it again: $ alias df='/usr/bin/df -x tmpfs' $ df -t tmpfs df: file system type 'tmpfs' both selected and excluded Have a nice day, Berny

As an interesting use-case (though not common), I recently configured a raspberry PI device, and wanted to mount as many locations on tmpfs as possible, e.g. "/tmp" "/var/tmp", "/var/log" etc. In was very useful in those cases to be able to see separate tmpfs file system listed, with information about how big they are and how much space was used. Also in other systems where "/tmp" is a "tmpfs", users might want to see how much space is available. If we hide it by default, they can of course use "df /tmp" or "df --all" - it's not about removing this option, it is just about making users' life harder or easier, and making unexpected changes. I recently also encountered a change in a default behavior of a program which I've been using a very long time - and it is *very* frustrating to have something that worked "just fine" for so long being changed. > Here on my openSUSE:Tumbleweed system, I see the following: > > $ df -T > Filesystem Type 1K-blocks Used Available Use% Mounted on [...] > /dev/loop0 ext2 31729 31729 0 100% /FULL_PARTITION_TMPDIR [...] > > (The /FULL_PARTITION_TMPDIR is used by a special coreutils test.)

I agree, but think this needs to be communicated very well, and in advance - perhaps announce this change ahead of time to the respective package maintainers of each distribution - just so they'll know it's coming (and also have a way to revert it if they don't like it). > This seems to be a small change, and not satisfying the snap case. Possibly hiding "squashfs" of readonly-mounts could get rid of those snaps? regards, -assaf

It is certainly inconvenient if that's not what you are looking for
(and certainly most desktop users aren't).
But I'm not sure if it's easy to find a set of criteria
that would work well while having minimal unexpected side effects of
hiding entries people in other systems do expect to see.
Out of curiosity,
can you share the output of the following commands on the same system?
lsblk
df -x tmpfs -x devtmpfs -x squashfs
Thanks,

What is so special about tmpfs so that you would like to see it? Here on my openSUSE:Tumbleweed system, I see the following: $ df -T Filesystem Type 1K-blocks Used Available Use% Mounted on devtmpfs devtmpfs 10187924 8 10187916 1% /dev tmpfs tmpfs 10199048 45788 10153260 1% /dev/shm tmpfs tmpfs 10199048 18036 10181012 1% /run tmpfs tmpfs 10199048 0 10199048 0% /sys/fs/cgroup /dev/sda2 ext4 20511312 12141864 7304488 63% / /dev/loop0 ext2 31729 31729 0 100% /FULL_PARTITION_TMPDIR /dev/sda5 ext4 619142920 390088908 229037628 64% /media/big_data /dev/sda3 ext3 103085876 90714416 7128248 93% /home tmpfs tmpfs 2039808 20 2039788 1% /run/user/1000 (The /FULL_PARTITION_TMPDIR is used by a special coreutils test.) I think I could well live with adding 'devtmpfs' and 'tmpfs' to the pseudo file systems in gnulib's "mountlist.c". This seems to be a small change, and not satisfying the snap case. Yet, I agree with Assaf that changing the defaults has to be done with caution. Eliding r/o filesystems or where usage<1% doesn't look like such. Have a nice day, Berny

But let's face it, df's utility for ordinary interactive use has degraded significantly with time due to all the random filesystems people have been adding, and we shouldn't keep our heads in the sands about this. df's default needs to change, one way or another. I mean c'mon, here's the output of 'df' on the Ubuntu 18.04.3 LTS workstation I'm typing this particular message on. In any sane system there would be only four lines of non-header output (for tmpfs etc, /, /home, and /media/eggert/B827-D456), but df is outputting 28 lines. This is ridiculous.

I would humbly suggest caution with such unexpected user-facing changes
to the default output of 'df' - learning the lessons from changing the
quotes in 'ls'.
Countless users have been using 'df' in their own ways, and have gotten
used to certain outputs.
This thread originated by a request to "clean up" the output on newer
ubuntu machines which use "snap" packages as /dev/loopN .
Let's not turn that into a drastic change that will affect many other
existing systems - the users on other systems did not ask for any changes.
---
Specifically for "default drop filesystems where usage is 1% or less" -
I can think of few cases off the top of my head where this would be
extremely confusing:
- I recently installed a 33TB raid file system. The usage on that system
is at %1 and will stay like so for at least several days.
- Amazon cloud services (AWS) offers an NFS4 service (they call it
"EFS") that has reported size of 8 exabytes. There too usage could be at
%1 for a long long time.
---
For cases where I want to list only the "real" storage, I typically use
an alias such as:
alias dff='df -h -x tmpfs -x devtmpfs'
And it would be very easy and least disruptive to recommend
to ubuntu users to add "-x squashfs" or another file system to ignore.
Perhaps we can come up with a recommended list of "lesser" file systems
to ignore (or conditions such as read-only file
systems) and add it as a new option, but please let's not make it the
default.
My two cents,
- assaf

What df tries to show now is a deduplicated list of file systems that have consumable storage. Maybe read-only could be valid to drop by default, but I've worked on systems where certain file-systems were read-only most of the time, but they were consumable. I wonder could we key (also) on used==0||available==0. cheers, Pádraig

Well if you want to exclude nested file systems like that, you could try: alias df='df -x squashfs' cheers, Pádraig

Hope it's still active and the right place for feedback. With recent changes to Ubuntu and the increasing use of 'snap' packaging for all sorts of things, the 'df' utility output is now quite jumbled and messy. My fairly normal system now has 17 /dev/loopNN mounts for various different software packages. I would rather not see these things by default. Or at least, I would like to have a convenient single-character flag that allows me to suppress those mounts from my 'df' output. One useful approach would be a flag that suppresses read-only filesystems. Another approach would be to suppress read-only filesystems that have no free space. Perhaps there are other good approaches too. I don't know if this issue is also relevant for 'docker' or not.
