Thanks Patrick, taking this a step further, it seems to me that the
only parameter for du that, to me, provides the correct file size is
-b as shown below. I am listing my Desktop directory via ll, du -hs
and du -bhs. Just further to this is it a bug with du that the -a
parameter which is supposed to list all files not just directories,
does not list files prefixed with a '.'?:
The du command is doing exactly what it is told to do. It is your
_shell_ that is expanding the "*" into a list of names that does not
(by default) include "dot" names. The du command is never asked to
look at the current directory, and thus will never see the dotfiles,
regardless of what flag arguments you use. What you are complaining
about is like running "du -a [abc]*" and complaining that names
beginning with "d" were not included.
Whenever you have questions like this, you should run "set -x" in the
shell to see exactly how commands are being invoked. (Run "set +x" to
turn that off again.)
I'm not sure what the point of this command is relative to du, it seems
to be more relevant when using commands that are aliases.
Having issued the command "set -x", if I issue the command du -abh
/home/steve/workspace it just echos that command back, and if I issue
the command du -abh /home/steve/workspace/* it echos the command with a
list of sub-directories of workspace that du is going to do its work
over. If I issue my alias command "la /home/steve/workspace" it echos
back the command "ls --color -a /home/steve/workspace", which is much
more meaningful.
regards,
Steve
