you have a strangely named file in opt.

ls -lb should gibe you an idea.

sorry - I meant give, not gibe.

If you have a file named "-p" then this will be put in place of the asterisk, and the command becomes:

# du -sk -p | more

I believe there is Typo error while giving the command

As confirmed above you might have entered

$ du -ks -p
du: illegal option -- p
usage: du [-a|-s] [-kbrx] [-t type] [name ...]
$

>> Please execute again and let us know the error which you are getting

# /usr/bin/du /opt

> du -sk *| morethis message appered to me illegal option --p

Here is what happened: the "*" was expanded by the shell (as it always does) to place all the names of the files and directories in your current working directory. It is very important to understand how the shell rewrites your command line. Your current directory contains a file with the name "-p" which produced the error. Try this same command (without the | more) like this:

echo du -sk *

You will see what the du command will see -- a list of all the filenames in your current directory. Since du always descends into the subdirectories, you dop not need "*". Just use either of these commands:

du -sk /opt
or
cd /opt
du -sk

However, since you are looking for unexpected space usage, you should use this command:

du -kx /opt | sort -rn | head -20

This will show you the largest directories, which is better than showing a summary of all the directories in alphabetical order.

Unexpected growth in /opt usually means there may be some logfiles stored there -- not a good place. When you find logfiles, either configure the applications that created them to put them in /var/opt, or replace the logfile with a symbolic link to /var/opt/.

If you do have a junk file in /opt/ you should remove it.
rm -i ./--p
You could also use: du -kxs -- *
