💡 Hint

Common Mistakes

Using '-O' saves the file with the remote name, not a custom name.

Using '-d' is for sending data, not downloading.

Using '-L' follows redirects but does not specify output file.

The '-o' option in curl specifies the output filename for the downloaded file.

Complete the code to download a file and show progress bar with wget.

Bash Scripting

wget [1] https://example.com/file.zip

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

A--show-progress

B-q

C-b

D-O

💡 Hint

Common Mistakes

Using '-q' hides output, so no progress is shown.

Using '-b' runs wget in background, no progress shown.

Using '-O' specifies output file, not progress.

The '--show-progress' option in wget shows a progress bar during download.

Fix the error in the script to download multiple files listed in urls.txt using wget.

Bash Scripting

while read url; do
  wget [1] "$url"
done < urls.txt

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

B-b

C-q

D-i

💡 Hint

Common Mistakes

Using '-i' expects a file input, but here URLs are read from a file already.

Using '-b' runs in background, not needed here.

Using '-q' suppresses output, not fixing errors.

The '-c' option allows wget to continue downloads if interrupted, useful in loops.

4fill in blank

hard

Fill both blanks to create a script that downloads files from a list and logs output.

Bash Scripting

while read url; do
  curl [1] "$url" -o "$(basename "$url")" >> download.log 2>&1
  sleep [2]
done < urls.txt

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

💡 Hint

Common Mistakes

Using '-L' follows redirects but does not silence output.

Using '2' seconds sleep might be too short for some servers.

Not using silent mode causes cluttered logs.

Use '-s' for silent curl output and '5' seconds sleep between downloads to avoid overload.

5fill in blank

hard

Fill all three blanks to create a robust download script with retries and timeout.

Bash Scripting

curl [1] --retry [2] --max-time [3] -O https://example.com/data.csv

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

A--retry-connrefused

B3

C30

D--silent

Attempts:

3 left

💡 Hint

Common Mistakes

Using '--silent' hides output but does not control retries or timeout.

Setting retries too high can cause long waits.

Timeout too low may abort downloads prematurely.

Use '--retry-connrefused' to retry even if connection refused, retry 3 times, and timeout after 30 seconds.
