How many directories will be created by the command 1mkdir dir-{0..9} && mkdir dir-100 || mkdir dir-1

To determine the number of directories that will be created by the given command, let's break it down step by step:

1. The command starts with "mkdir dir-{0..9}". This is a brace expansion syntax that expands to "mkdir dir-0", "mkdir dir-1", "mkdir dir-2", and so on, up to "mkdir dir-9". So, this part of the command will create 10 directories.

2. Next, the command includes "&&" which is a logical AND operator. This means that the following command will only be executed if the previous command (mkdir dir-{0..9}) is successful.

3. The next command is "mkdir dir-100". This will create a single directory named "dir-100".

4. Finally, the command includes "||" which is a logical OR operator. This means that the following command will only be executed if the previous command (mkdir dir-100) fails.

5. The last command is "mkdir dir-1". This will create a single directory named "dir-1".

In summary, the command will create a total of 12 directories: dir-0, dir-1, dir-2, dir-3, dir-4, dir-5, dir-6, dir-7, dir-8, dir-9, dir-100, and dir-1.
