I want to define a variable pointing to my desktop location, in bash I say

desktop="\"/cygdrive/c/Dokumente und Einstellungen/Luntain/Desktop\""

When I echo it looks ok, and yet when I input cd $desktop it complaints
that there is no /cygdrive/c/Dokumente directory. wtf? I also tried
defining desktop using '\ ', that is

desktop="/cygdrive/c/Dokumente\\ und\\ Ein...

I do it obviously in cygwin bash, and I don't know if it would work on
Linux.

If the value of a variable contains whitespace, you must quote the
variable name when you reference it, if you want shell to treat it
as a single argument. Otherwise, shell interprets the spaces as
argument delimiters.

This means,

cd $desktop

is interpreted as a cd command with three arguments:

cd "/cygdrive/c/Dokumente" "und" "Einstellungen/Luntain/Desktop"

The cd command uses a single argument, so it will attempt to change
your working directory to /cygdrive/c/Dokumente, which does not exist.
If you surround the referenced variable name with double quotes,

cd "$desktop"

the shell will preserve the spaces and interpret this as a cd command
with a single argument

cd "/cygdrive/c/Dokumente und Einstellungen/Luntain/Desktop"

which is what you desire.

I am not that lame not to now that spaces seperate arguments.

I would like to point out that I assign a quoted string to desktop variable:

desktop="\"/cygdrive/c/Dokumente und Einstellungen/Luntain/Desktop\""

when I echo $desktop, the path is displayes with the enclosing quotes. I
don't understand why cd doesn't seem to see the quotes. I want to have a
quick way of changing to my desktop directory, this is the hole point of
that desktop variable. There must be a way.

cd "$desktop" is one way. Another way is to use the CDPATH variable.

This is the expected behaviour. You can have a directory with
a name like: abc"xyz
in that case, you can cd in this way:
cd abc\"xyz

try: desktop="bla bla bla with as many / as you want"

But the \ is the scape character (special meaning). If you want a \
without special meaning, use \\

try just:

cd

The quotes are not part of the path; remove them.

desktop="/cygdrive/c/Dokumente und Einstellungen/Luntain/Desktop"

When you use it, quote the variable, e.g.:

cd "$desktop"

Quote processing is not performed on the result of variable expansion.
So it's looking for a filename that actually starts with doublequote.

CDPATH is what I need, thx.

CDPATH=".:/cygdrive/c/Dokumente und Einstellungen/Luntain"
