I am attempting to create a spreadsheet to document the content of

Gparted displays the desired information.
*HOWEVER* I see no way to capture the information.

At the command line using "lsblk -o NAME,FSTYPE,LABEL /dev/sdb" gives
most of the desired information.

It omits partition size, used space, and unused space.

Suggestions?

Sometimes I append output from lsblk or parted -l.

hdparm and smartctl might also provide some of what you're looking for.

I'll attempt to redefine my problem.

I have:
   multiple machines
each having
   multiple disks
each having
   multiple partitions.

I wish to inventory the above "conglomeration".

I wish to to answer the question(s):
   How big is each
   How much is available

It appears that you're really interested in the filesystems'
information rather than the partitions', with the exception of the
filesystem LABELs, which you have said elsewhere you use as
indications of the filesystems' contents.

That's likely. There are some terminology issues I'll have to follow up on so that I'll use terms in ways compatible to others.


So it looks as if   df --output -x tmpfs -x devtmpfs   gives you all
you want (and more) with the exception of LABELs.

No. The man pages states it only looks at mounted partitions due to "...nonportable intimate knowledge of file system structures]. As I only have FAT and ext partitions, what I want should be doable if not already done.

It seems sensible
to use   lsblk -o NAME,LABEL -l   to get these because AFAICT it
automatically handles the business of selecting e2label/dosfslabel/etc
as appropriate and gets them all in a heap.

With judicious use of head, tail and sort, it would be fairly simple
to get the two listings to correspond well enough for entry into a
spreadsheet (I don't know what you meant by 'generic'), making
final adjustments (df omits the device and partitions like swap) to
line things up.

I'm going to have to reread this thread. There is something in the back of mind hinting at a solution. It will require some scripting to pull pieces together, but that was assumed to be likely anyway.

Later.
