Task $1.$ Check file and directory details

In this task, you must explore the permissions of the projects directory and the files it contains. The lab starts with $/$home$/$researcher$2$ as the current working directory. This is because you're changing permissions for files and directories belonging to the researcher$2$ user.

Navigate to the projects directory.

List the contents and permissions of the projects directory.

The permissions of the files in the projects directory are as follows:

total $20$

drwx$--$x$---2$ researcher$2$ research$\_$team $4096$ Oct $1418$:$40$ drafts

$-$rw$-$rw$-$rw$-1$ researcher$2$ research$\_$team $46$ Oct $1418$:$40$ project$\_$k$.$txt

$-$rw$-$r$-----1$ researcher$2$ research$\_$team $46$ Oct $1418$:$40$ project$\_$m$.$txt

$-$rw$-$rw$-$r$--1$ researcher$2$ research$\_$team $46$ Oct $1418$:$40$ project$\_$r$.$txt

$-$rw$-$rw$-$r$--1$ researcher$2$ research$\_$team $46$ Oct $1418$:$40$ project$\_$t$.$txt

Note: The date and time information returned is the same as the date and time when you ran the command. Therefore, it is different from the date and time in the example.

As you may recall from the video lesson, a $10-$character string begins each entry and indicates how the permissions on the file are set. For instance, a directory with full permissions for all owner types would be drwxrwxrwx:

The $1$st character indicates the file type. The d indicates it$$s a directory. When this character is a hyphen $(-),$ it's a regular file.

The $2$nd$-4$th characters indicate the read $($r$),$ write $($w$),$ and execute $($x$)$ permissions for the user. When one of these characters is a hyphen $(-)$ instead, it indicates that this permission is not granted to the user.

The $5$th$-7$th characters indicate the read $($r$),$ write $($w$),$ and execute $($x$)$ permissions for the group. When one of these characters is a hyphen $(-)$ instead, it indicates that this permission is not granted for the group.

The $8$th$-10$th characters indicate the read $($r$),$ write $($w$),$ and execute $($x$)$ permissions for the owner type of other. This owner type consists of all other users on the system apart from the user and the group. When one of these characters is a hyphen $(-)$ instead, that indicates that this permission is not granted for other.

The second block of text in the expanded directory listing is the user who owns the file. The third block of text is the group owner of the file.

What is the name of the group that owns the files in the projects directory?

researcher$2$

research$\_$team

security$\_$team

other$\_$users

Check whether any hidden files exist in the projects directory.

Which of these files is hidden in the projects directory?

$.$project$\_$x$.$txt

$.$project$\_$m$.$txt

There are no hidden files

$.$project$\_$r$.$txt

You have not completed this task. You can use the ls $-$l and ls $-$la commands to check the permissions of the projects directory and to check if it contains hidden files.
