Practice - 5 Tasks

1fill in blank

easy

Complete the command to copy a file named file.txt from your local machine to a remote server using scp.

Linux CLI

scp file.txt user@remote_host:[1]

Drag options to blanks, or click blank then click option'

Auser@remote_host

B-r

Cfile.txt

D/home/user/

💡 Hint

Common Mistakes

Putting the filename again after the colon instead of the destination directory.

Using -r when copying a single file.

Repeating the user and host after the colon.

The destination path on the remote server must be specified after the colon. Here, /home/user/ is the target directory.

Complete the rsync command to copy the directory myfolder from the remote server to your local machine.

Linux CLI

rsync -avz user@remote_host:[1] ./

Drag options to blanks, or click blank then click option'

A/home/user/myfolder

B-r

Cmyfolder/

Dmyfolder

💡 Hint

Common Mistakes

Using relative paths without full remote path.

Adding -r inside the source path.

Omitting the user and host before the colon.

You need to specify the full path of the directory on the remote server. /home/user/myfolder is the correct full path.

Fix the error in the scp command to copy a directory project recursively to the remote server.

Linux CLI

scp [1] project user@remote_host:/home/user/

Drag options to blanks, or click blank then click option'

A-r

B-v

C-a

D-z

Attempts:

💡 Hint

Common Mistakes

Using -a which is not valid for scp.

Omitting the recursive option causes an error.

Using compression option -z which scp does not support.

The -r option tells scp to copy directories recursively.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps filenames to their sizes using rsync output stored in files.

Linux CLI

sizes = { [1]: [2] for [1] in files }

Drag options to blanks, or click blank then click option'

Afile

Bfiles[file]

Csize

Dfiles[size]

Attempts:

💡 Hint

Common Mistakes

Using size as the loop variable instead of file.

Accessing dictionary with wrong key variable.

Swapping keys and values in the comprehension.

The variable file iterates over files. The size is accessed by files[file].

5fill in blank

hard

Fill all three blanks to filter files larger than 1000 bytes from files dictionary using comprehension.

Linux CLI

large_files = { [1]: [2] for [1] in files if [2] [3] 1000 }

Drag options to blanks, or click blank then click option'

Afilename

Bfiles[filename]

C>

D<

Attempts:

3 left

💡 Hint

Common Mistakes

Using different variable names for key in comprehension.

Using < instead of > for filtering.

Comparing the key instead of the value.

We iterate over filename in files. The size is files[filename]. We filter sizes greater than 1000 with >.
