df without line wrap on long FS name

-P uses the POSIX output format, which makes information on each file system always printed on exactly one line. "column -t" makes a table from the input.

df output, sorted by Use% and correctly maintaining header row

Show disk space info, grepping out the uninteresting ones beginning with ^none while we're at it.

The main point of this submission is the way it maintains the header row with the command grouping, by removing it from the pipeline before it gets fed into the sort command. (I'm surprised sort doesn't have an option to skip a header row, actually..)

It took me a while to work out how to do this, I thought of it as I was drifting off to sleep last night!

No need for grep | awk. -P on df will force the mount point to be on the same line as the device

find the device when you only know the mount point

most usefull when creating batch scripts using several usb drives and some commands like mkntfs needs a device name

the -w option for grep is here to filter lines when you have multiple drives with the same volume label. Without this option, the grep command will return

/media/KINGSTON

/media/KINGSTON_

/media/KINGSTON__

tune2fs also provides the same information . But the information does not give the current usage , it gives the information when the file system was last mounted.

Continually monitor things

You can use this one-liner for a quick and dirty (more customizable) alternative to the watch command. The keys to making this work: everything exists in an infinite loop; the loop starts with a clear; the loop ends with a sleep. Enter whatever you'd like to keep an eye on in the middle.

Report full partitions from a cron

Reports all local partitions having more than 90% usage.

Just add it in a crontab and you'll get a mail when a disk is full.

(sending mail to the root user must work for that)

Fill up disk space (for testing)

For disk space constraint testing. Leaves a little space available for creating temp files, etc. Easily free up the used disk space again by deleting the dummy00 file. Can tailor the testing by building smaller 'blocks' to suit the needs of the testing.

WARNING: do not do this to the '/' (root) filesystem unless you know what you are doing... on some systems it could crash the OS.
