The following command created directory called 'rubbish100'.
I didn't create it as a super user.
Where does it reside?

cd ~/ && mkdir .rubbish100

ni@linux-j5q7:~> cd ~/ && mkdir .rubbish100
ni@linux-j5q7:~>


ni@linux-j5q7:~> rmdir rubbish100
rmdir: failed to remove `rubbish100': No such file or directory
ni@linux-j5q7:~>

Where does it reside? How do I remove it?

Your thoughts are welcome.

You created it with a . in front that makes it a normally not visible directory. use ls -a to see it. To remove it just do rmdir .rubbish100

Hi Gins, You missed a "." try this.Good luck. ;-)

Gins, please use useful thread titles next time.

I do not know what this sign ' && ' is doing here. What does it mean?

Sometimes back you touced on the topic of sensible thread title.

This my stupidity.

I have to eat humble pie.

first execute the "cd ~" command (change directory to /home/_username_ ) and if (and only if) it succseeds, execute "mkdir .rubbish100" after that.
so:
the command changed the working directory to ~ (the base of the home directory of the user who runs the command) - and then created a directory ".rubbish100" inside the /home/_username_ directory of the user from which the command was run/of the user you where logged in as.

Thanks jomen for the reply.

cd ~/ --> It is obvious that this changes to /home/ni.

What is ' && ' doing?

I just tried without ' && ' and it worked fine.

Please read the following:


ni@linux-j5q7:~> cd ~/ mkdir .rubbish100
ni@linux-j5q7:~>

---------------------------------------
I tried in vain to remove it.

ni@linux-j5q7:~> rmdir rubbish100
rmdir: failed to remove `rubbish100': No such file or directory
ni@linux-j5q7:~>

ni@linux-j5q7:~> rmdir .rubbish100
rmdir: failed to remove `.rubbish100': No such file or directory
ni@linux-j5q7:~>

ni@linux-j5q7:~> rmdir /.rubbish100
rmdir: failed to remove `/.rubbish100': No such file or directory
ni@linux-j5q7:~>

How do I remove it?

"a && b" means execute a and following a successful exit, run b.

anyway, a file called "rubbish100" is very obviously not the same file as one called ".rubbish100" just as it is not a file called "bob" or "flipper_the_table_tennis_playing_baboon" they clearly have different names. no more confusion about that please.

"cd ~/ mkdir .rubbish100" is two commands crammed into one, so never going to do what it should. does this dir actually exist? you know how to use ls right?? you know to use the -a flag?

Gins, this has been explained to you and it is very basic:
What is ' && ' doing? - as jomen said: first execute the "cd ~" command (change directory to /home/_username_ ) and if (and only if) it succseeds, execute "mkdir .rubbish100" after that.

You need to issue ls -la in your home directory - that will list all files and folders stored there. See if the folder .rubbish100 is there at all, if not it would give you a hint as to why you can't delete it.

and trying to delete /.rubbish100 will fail because you are asking the system to delete a file or folder from your root directory when the folder was created in your home directory.

See if the file or folder is in your home directory before you try to remove it.

Thanks acid kewpie and XavierP for taking time to reply me.

I know there is a difference between '.rubbish100 ' and 'rubbish100' in this situation.

I didn't know the following:
"a && b" means execute a and following a successful exit, run b.

I ran the command 'ls -la' even as a superuser.

I didn't find the file in question.

It may be the file creation didn't take place.

What do you think?

it clearly isn't there if ls doesn't show it.

Hey Gins,

You can change to your home directory anytime by typing cd by itself. Typing cd ~ or cd ~/ will do the same thing, but why waste time typing extra characters.

If you want to execute multiple commands on one line, use the semicolon to separate the commands. For your example

cd ; mkdir .rubbish100

cd && mkdir .rubbish100

The semicolon separator will run the next command weather the first command was successful or not. The && uses the exit status of 0 or true. If the first command was susccesful, the second command is executed. If not, the second command is not executed.

To remove a directory, type rmdir .rubbish100

Note: rmdir works only on empty directories, use rm -rf to delete a directory with files. Use with caution.
