Hi!
I have a disk that is filling up, but I don't know what directory is currently being written to. Is there a command that will tell me which directory is being written to?

Thanks,

Look at the find command.

find -size +100000c

for instance, will find all files that are at least 100000 bytes large, starting at the current directory and recursively searching the subdirectories.

This will also surface directories which have become very large, perhaps due to lots and lots of files being written into them.

You can set options to look at directories only if you wish, thusly:

find -size +100000c -type d

will turn up all directory inodes that are at least 100000 bytes long (meaning a LOT of files in them).

I once found that a misconfigured postfix was sending emails to me which were not going out, and it was sending them once a minute. My hard drive space was vanishing. By the time I found the problem, there were about 2 million files in /var/spool/something or other, all to be sent to me.

I found it because of an extraordinarily large directory turned up by find.

You can also launch Konqueror file manager, right click on a directory, click properties, and it will tell you the size of the contents in each directory you do this with. This is a good starting point to find where to start looking. You can use the man page for find, and have find find the files written in the last minute. This should also give some clue.

If you're using Gnome, go to Applications -> System Tools -> Disk Usage Analyzer. This utility can scan you entire filesystem and show you the folders that take the most space.

Alternatively, you can use this command :
This will show you all subfoders, ending with the ones taking the most space. So basically, to scan your entire filesystem, you should run it from "/". To scan your home folder, you should run it from "/home/you", etc.

It wasn't clear; maybe you wanted more of a high level view of what was happening to your partitions, in which case you should try

or, for more detail about directories (folders):

(which gives an output similar to some of the 'find' options). (And, if you are using SuSE, yast gives you nice little bars in the software installation utility, although it doesn't really have any more information than df. But it is more 'visual'.)

Hmmm...

Do you think we've given the OP enough different way to do similar things?
