Sometimes when I make a typo in the terminal and accidentally tell Bash to interpret /, I get the output bash: /: Is a directory. Now I believe this output has to deal with the root directory or something of that sort.
But what I don’t understand is that when I enter increasing amounts of forward-slashes it continues to output the same thing…
Examples
//// —> bash: ////: Is a directory
//////// —> bash: ////////: Is a directory

/ is the directory delimiter. Any string that ends in it is by definition a directory name:
example #This could be a file or directory
example/ #This is a directory in the current directory
/example/ #This is a directory in the root directory
Thus a series of /‘s would be interpreted an a series of {null} directories.

Этот вопрос уже имеет ответ здесь: что такое каталог с двойной косой чертой (//)? 1 ответ
Иногда, когда я делаю опечатку в терминале и случайно говорю Bash интерпретировать /, я получаю вывод bash: /: Is a directory. Теперь я считаю, что этот вывод должен иметь дело с корневым каталогом или чем-то подобным.
Но я не понимаю, что, когда я ввожу увеличивающиеся количества спреев, он продолжает выводить одно и то же …
Примеры
//// -> bash: ////: Is a directory
//////// -> bash: ////////: Is a directory

/ является разделителем каталогов. Любая строка, которая заканчивается на нем, по определению является именем каталога:
example #This could be a file or directory
example/ #This is a directory in the current directory
/example/ #This is a directory in the root directory
Таким образом, серия из / s будет интерпретирована как серия {null} каталогов. [ ! d2]

In the example
~/fuse/example>
is a prompt, not part of the command. The command issued is:
./hello /tmp/fuse -d
Where hello is this code compiled. (Compile line at top of page).
Actually, due to the redirect, if you have hello compiled in the home directory of your user:
/home/memsql/
the file is overwritten (as empty) due to the > redirect from the command, which produces no output. Else, an empty file named hello is created.
Bash interprets you as trying to issue a directory as a command, as in:
$ /homeEnter bash: /home: Is a directory $ /proc/Enter bash: /proc/: Is a directory $ /home/ asdf asdf asdf blah blahEnter bash: /home/: Is a directory
So in your example:
$ ls -F1 ~
bar
Documents/
fuse-2.9.3/example/
gaz
$ ~/fuse-2.9.3/example> ./hello /tmp/fuse -d
bash: /home/memsql/fuse-2.9.3/example: Is a directory
$ ls -F1 ~
bar
Documents/
fuse-2.9.3/example/
gaz
hello <--- new empty file
When I follow the steps for starting a new Cordova PhoneGap project for Eclipse (following these directions: http://docs.phonegap.com/en/2.2.0/guide_getting-started_android_index.md.html#Getting%20Started%20with%20Android ), I drag Android’s /bin directory to the Terminal window first (which contains the create script), then type in:
./create /Users/Steve/Documents/PhoneGap_apps/PhoneGap_apps/appName2 com.companyname.appName2 appName2
to create the project.
But what I get in return is:
-bash: /Users/Steve/Downloads/phonegap-phonegap-8a3aa47/lib/android/bin: is a directory
The appName2 directory is not created.
Why do I get that «is a directory» notice, and how do I resolve it to create the directory?

Edit: Fixed path.
I think you’re missing a tilde (~) in your path.
Try this:
./create ~/Documents/PhoneGap_apps/PhoneGap_apps/appName2 com.companyname.appName2 appName2

I successfully created the folder based on Marcus’ response by adding the «cd» first, then adding the entire script. Earlier, attempting his answer, I had first hit Return after dragging the /bin folder over, then adding the script. Doing all three components on a single line did the job.

So I encounter this «bash: Is a directory» error while trying to run the following command on my Arch Linux VirtualBox. GNU bash version 4.3.30(1).
/home/minix git clone git://git.minix3.org/minix src
I have checked if I have git installed. And it is in /usr/bin/git.
I am completely lost, so any help would be much appreciated.
asked Oct 25, 2015 at 14:11
The error is shown because you’re trying to run /home/minix as a command (with git clone ... as its parameters).
Why is that directory name there? Did you add it for a specific reason? Did it get copypasted off the web along with the rest of the command? If not, the following should be enough:
git clone git://git.minix3.org/minix
