Network monitoring script in Bash Scripting - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to ping a host once and check if it is reachable.

Bash Scripting

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

B5

C0

D10

💡 Hint

Common Mistakes

Using 0 or no count sends unlimited pings.

Using too many pings delays the check.

The -c option specifies the number of ping requests to send. Using 1 sends a single ping.

2fill in blank

medium

Complete the code to store the ping command's exit status in a variable.

Bash Scripting

ping -c 1 8.8.8.8
status=[1]

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

A$!

B$?

C$#

D$$

💡 Hint

Common Mistakes

Using $! which holds the last background process ID.

Using $$ which holds the current script's PID.

The special variable $? holds the exit status of the last command run.

3fill in blank

hard

Fix the error in the if statement to check if the ping was successful.

Bash Scripting

if [ [1] -eq 0 ]; then
  echo "Host is reachable"
else
  echo "Host is unreachable"
fi

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

Astatus

B$?status

C$status

Dstatus$

💡 Hint

Common Mistakes

Using variable name without $ causes string comparison, not numeric.

Adding $ in wrong place causes syntax error.

Variables in bash must be prefixed with $ to get their value inside conditions.

4fill in blank

hard

Fill both blanks to create a loop that pings a host 3 times and prints the result each time.

Bash Scripting

for i in [1]; do
  ping -c 1 8.8.8.8
  result=$?
  if [ $result [2] 0 ]; then
    echo "Ping $i: Success"
  else
    echo "Ping $i: Fail"
  fi
done

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

A"1 2 3"

B==

C-eq

D1 2 3

Attempts:

3 left

💡 Hint

Common Mistakes

Using quotes around numbers makes the loop treat it as one string.

Using == instead of -eq causes numeric comparison errors.

The loop iterates over the numbers 1 2 3 (without quotes). The numeric comparison operator for equality in bash is -eq.

5fill in blank

hard

Fill all three blanks to create a script that logs ping results with timestamps to a file.

Bash Scripting

for i in [1]; do
  ping -c 1 8.8.8.8 > /dev/null
  status=$?
  echo "$(date [2]) Ping $i: $[3]" >> ping_log.txt
done

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

A1 2 3 4 5

B"+%Y-%m-%d %H:%M:%S"

Cstatus

Dresult

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong variable name for status.

Not quoting the date format string.

Using too few or too many loop iterations.

The loop runs 5 times. The date command uses the format string "+%Y-%m-%d %H:%M:%S" for timestamps. The variable holding ping success is status.
