Re: [PLUG] Running out of disk space?

[Lynn Bradshaw via plug <plug@lists.phillylinux.org>]

Sorry, folks, it's been years since I used a mailing list like this
one (high school, actually) and I've only recently encountered
relearning the ropes. I sent out a response to just one individual
when it was meant for the whole list. It had to do with a user's
long-term storage device filling up and various strategies were
recommended. These were:

* Use a live distribution: fantastic idea, Ubuntu maybe or perhaps Linux Mint
* Use "mount" and show us the output
* Use "du" with appropriate flags and current directories and show us the output
* Use "df", probably with "-h" too and show us the output

If we pull together and get all of these data, the fellow Linux user's
troubles can be squared away. The suggestion that /boot was too full
is certainly possible but possibly /home or /var or /tmp are too
clogged and there's no way of knowing without the file system data. So
let's get those data and hunt down the bug.
