10. Create a new text file and verify that the above command worked properly.

11. Write a single command take away all permissions from user, group, and others from the three files you created in this lab.

10. To create a new text file, you can use the touch command followed by the name of the file you want to create. For example, to create a file named "newfile.txt", you can use the following command:

```
touch newfile.txt
```

To verify that the command worked properly, you can use the ls command to list the files in the current directory and check if the new file is listed. For example:

```
ls -l
```

This will list all the files in the current directory along with their permissions, ownership, and other details. You should see the new file listed with "-rw-r--r--" permissions, indicating that it is a regular file with read and write permissions for the owner and read-only permissions for others.

11. To take away all permissions from user, group, and others from the three files you created in this lab, you can use the chmod command with the "000" permission code. For example, if you have three files named "file1.txt", "file2.txt", and "file3.txt", you can use the following command to remove all permissions from them:

```
chmod 000 file1.txt file2.txt file3.txt
```

This will set the permissions of all three files to "---------", which means that no one (not even the owner) has any permissions to read, write, or execute the files.
