no such file or directory using "-" character

[Angelo Moreschini]

Hi

I need to go inside a directory named <notebook-source>;
but I am not able to do it.

Using the command cd /.../notebook-source
I get the output :
"no such file or directory"
-----------
I tried to go around to the problem using the command ls :

if I use the command :
<ls notebook* > (using the wildchar *)
then I get the correct output:
"notebook-source".

but if I use the command :
<ls notebook-source >
then I get (again) the message
" no such file or directory"

Why this happen ?
=====

Seem that the problem is connected with the use of the character "-"
 inside the name of the directory.... ; but I didn't know the character "-"
is forbidden to form nane of the files or directories..

What is my problem?
It is some thing that I dont know about the rules to form name of files and
directories ?

Regards
thank you

Angelo

Hi Angelo,

probably: cd ~/notebook-source,
or directly: cd notebook-source???

What do you mean by "/.../"?

I guess, the leading /.../ is the culprit.

Probably, "notebook-source" contains ome or more space chars at the end,
and you do not see then.

Try this: ls notebook* >x and then check the file "x" for space chars,
or use the tr command: ls notebook*|tr " " "<some no space char>"

Sorry, I meant:

Try this: ls -d notebook* >x and then check the file "x" for space chars,
or use the tr command: ls -d notebook*|tr " " "<some no space char>"

An addendum to Joachim's suggestion:  possibly try

ls -d notebook* | od -tx1

.. to look for funny alternate characters.  Maybe the hyphen is some 
funky Unicode like an en-dash, depending upon how it was created.

As others have suggested, you have hidden chars in the directory name.
Any of the suggestions given will help you see what those hidden chars are.

One simple method to change the name without knowing what the hidden chars are:

mv notebook* xxxxx
mv xxxxx notebook-source

Of course, assuming you "need" to keep the name as notebook-source

Now, you can
cd notebook-source

Good luck

"cd /.../" is not legal.

in using "/" you specify the root path.
in using "..." that is an illegal directory designation.

the 1st is a given rule of indication origin of a path.

entering just "..." as a directory designation gives you;

]$ cd ...
   bash: cd: ...: No such file or directory
   ]$

understand?

I don't think that the OP actually used that; he was just using as a 
shorthand for an unspecified directory.

Not always.  ... is a valid name for a file or directory and I'm told 
that there was a time that games used it as a hidden directory under the 
directory they were installed in to stash score files.  I've never used 
it as a file name, but there was a time when I had ~/... as a directory, 
"just because."  In fact, you could easily store your help files under 
~/...---... if you really wanted to be silly.

It's perfectly legal. Whether it means anything or not depends on the
existence or otherwise of a directory called "/..." (the closing '/' is
ignored). The only system-reserved names are '/', '.' and '..'. Anything
else is legal, including <space> and <carriage-return> (though you may
have difficulty using them.

you and Joe Z are most correct 'el chemo brain' was not working working
when i ran;

]$ echo>...
   ]$ ls

where as;

]$ ls -a
   .  ..  ...

works.

thank you both for enlightening 'el chemo'. it should stick this time.
