It’s fairly easy to send a message to a Telegram Channel using curl. Copy and paste the following command in, replacing the API_TOKEN, chat_id, and test_message, with the appropriate items.
curl -s -o /dev/null -X POST -H "Content-Type: application/json" -d "{\"chat_id\": \"-100XXXXXXXXXX\", \"text\": \"test_message\", \"disable_notification\": true}" https://api.telegram.org/bot{API_TOKEN}/sendMessage

You can print a random number between 1-10 with the following command.
echo $((( RANDOM % 10 )+1))
If you change it so the output is between 0-9 you get decently even results.
cat /dev/null > random.txt && cat /dev/null > random2.txt && for ((i=0; i<=9999;i++)); do echo $((( RANDOM % 10 ))) >> random.txt ; done && for ((i=0; i<=9;i++)); do echo $(grep -c $i random.txt) $i; done | sort -n
Note that you can change the command to be between 1-10, but all the 1’s in 10 will get grepped and counted as 1’s.
The above command should return something similar to the following. Sorted by lowest occurrences first.
943 5 945 8 985 7 996 2 997 6 1005 3 1012 9 1016 4 1033 0 1068 1 admin@localhost:~$
We can plot them in LibreOffice Calc.
Gnuplot is another utility that you can use to plot numbers. Example is below.
cat /dev/null > random.txt && cat /dev/null > random2.txt && for ((i=0; i<=9999;i++)); do echo $((( RANDOM % 10 ))) >> random.txt ; done && for ((i=0; i<=9;i++)); do echo $i $(grep -c $i random.txt) ; done | sort -n | gnuplot -p -e 'plot "/dev/stdin"'
Create a file “list.txt” that contains all the URLs you want to download and launch the following command
for i in cat list.txt ; do wget ${i} && sleep $(( ( RANDOM % 120 ) +1 )) ; done
It’ll now run and after each link will wait a random amount of time up to 120 seconds before downloading the next link. Change the number as needed.
Change the 10 to however many seconds you need or want.
echo $(( ( RANDOM % 10 ) +1 ))
Example output
bob@localhost:~$ echo $(( ( RANDOM % 10 ) +1 )) 10 bob@localhost:~$ echo $(( ( RANDOM % 10 ) +1 )) 2 bob@localhost:~$ echo $(( ( RANDOM % 10 ) +1 )) 9 bob@localhost:~$
Sleep timer
sleep $(( ( RANDOM % 10 ) +1 ))
