There is no simple generic solution as it is shell dependent:
For tcsh or bash:
echo .[^.]*
For ksh:
echo .*
However, it will fail in Nykakin's case (files beginning with ..)
For a more generic answer, use "grep" or "find", like in:
ls -a|grep '^\.\(..\|[^\.]\)'
This works with all shells I know and doesn't have the Nykakin's case.
Also works with ...

a way (but may choke or have side effects on strange filenames, ie files whose name contain a newline! but also files containing * or a " or ... you get the picture ^^. Be very careful if using those way to list and use files)
$ for i in * .* ; do echo $i ; done | egrep -v '^\.$|^\.\.$' > /tmp/list_files_one_by_lines
$ while read a_file ; do echo ...

With tcsh 6.17.01 and above:
set globdot
du -s -- *
With older ones:
du -s -- * .[^.]* ..?*
(interestingly, that works better than its POSIX counterpart (* .[!.]* ..?*) because in tcsh (and in zsh in csh emulation (cshnullglob option)), contrary to POSIX shells, those pattern that don't match any file get expanded to nothing instead of themselves)

I usually use:
du -ks * .[^.]*
This way . and .. are not matched and it should be fairly portable.

Not sure if there is a tcsh builtin, but depending on the version of find you have, there is a workaround like this:
find -maxdepth 1 -not -name '.' -exec du -s '{}' '+'
If your find doesn't do the -exec COMMAND {} + syntax, you can try for -print0/xargs:
find -maxdepth 1 -not -name '.' -print0 | xargs -0 du -s

You can use ls -A command to not enlist . and .. inside command substitution:
echo "`ls -A`"

you must be knowing that Directory is nothing but a file that points to some list of files, basically it is a pointer, may be hidden or not.
in similar way . and .. are the pointer which point to Uppermost directory and upper directory respectively.
that is why i think when we execute
ls -a
command, these are displayed!

. and .. are hard links to the current and the parent directory
(/ is the parent of itself).
With the -a option ls shows all inodes in the current directory, i.e. also the hidden files which filenames begin with ad dot, therefore . and .. are shown.
