File$/$Folder$/$Permission Practice

Create a Directory

In your class folder on Elvis $($probably named UnixFiles$),$ create a

folder named FileTree$2.($If you completed FileTree$1,$ you can us$$

$\text{'}$cp $-$r$\text{'}$ to copy that folder.

In FileTree$2,$ create the following subtree of files and directories

Except for $"-$README.txt$",$ all the files were created with the touch

command, and are empty.

All the folders $($they have a $"$ d $"$ on the left$)$ were created with mkdir

$($See below for infore set using chmod

$($See below for information about $"0-$README.txt$".)$ Be sure you get the

names and permissions exact.

After you create a directory, you can cd into it to create any

subdirectories or files. To go back up$,$ remember that every folder

has an entry named $".."$ which points to the parent.

The output below is from running "tree $-$anp" in the reference folder.

$[$drwxr$-$xr$-$x$]$

$-[-$rw$-$r$-$r$-]]$

$[$dr$-$xr$-$xr$-$x$]$

$[$drwxrwx$-\backslash$cdots$]$ baz a

$\backslash [-$rw$*-$r$-$r$--]$ ditto

$-[$drwx$-$xr$-$x$]$ foo fonden

$\backslash$r$-$rw$-$r$-\%$

$8$ directories, $13$ files

The $"0-$README.txt$"$ file should be exactly $200$ characters long,

which you can check by running this command:

ls $-$l $0-$README.txt

The output should look something like this $($the file size has been

bolded below$)$: $$

rw$-$r$--$r$--1$ batman domain users $200$ Jan $1314$:$530-$README.txt

You can copy$/$paste this text to get your $"0-$README. txt$"$ file started:

This is file $0-$README.txt$.$

It was created by Bruce Wayne, username 'batman'.

It is supposed to be exactly $200$ characters long

Here are extras: $123456789012345678901234567890123456789012345678$

You should change it to have your name and username. You may

have to add$/$remove some of the extra characters at the bottom to

get the file to come out to exactly $200$ characters. Be sure it ends

with a newline!

Test If Your Folders Are Correct

While inside the FileTree$2$ folder, run the command $"/$opt$/$cs$/$

UnixFiles$/$testprogs$/$test$\_$tree$2"$

Loading configuration for FileTree$2...$ done.

Current Folder: $/$home$/$batman$/$UnixFiles$/$FileTree$2$

$0-$README.txt file: $$

$*******************$

This is file $0-$README.txt$.$

It was created by Bruce Wayne, username 'batman'

It is supposed to be exactly $200$ characters long.

File size is correct: $200$

Checking

Checking username: found 'batman' $.-$ correct

Checking names and permissions of all files.

$[$drwxr$-$xr$-$x$][-$rw$-$r$--$r$--]$

$\{$dr$-$xr$-$xr$-$x$]$

$-[$drwxrwx$---]$ baz

$[$drwx$-\backslash$cdots$---]$ A

$[$drwx$-----].$dotdir

$[$drwxr$-$xr$-$x$]$ foo $[-$rw$-$r$---]$ dott

E$[-$rw$--$r$-$r$--]$

$[$drwx$-\backslash$cdots$-**]$

$8$ directories, $13$ filesIf the output with the file looks like this:

Loading configuration for FileTree$2...$ done.

Current Folder: $/$home$/$batman$/$UnixFiles$/$FileTree$2$

$0-$README.txt file

This is file $0-$READE$**$

It was created by Bruce Wayne, username 'batman'

It is supposed to be exactly $200$ characters long

That means your $"0-$README.txt$"$ file didn't end with a newline.

Submit a Screenshot

If the test$\_$tree$2$ script reported something wrong, add$/$delete$/$move$/$

rename$/$edit files as needed, and then try again.

When the test$\_$tree$2$ script reports that all is well, make a screenshot

and upload it to Canvas.
