Variable completely messes up echoed string
So I really have no idea how to better describe this than the title.
So I discovered this website called pwnedpasswords, where you can apparently check to see if your password's sha1 hash has been leaked somewhere. So I made a script to automate the process, here's my script:
#!/bin/bash
read -s -p "Input your password: " your_pw
echo
your_hash=$(printf "$your_pw"|sha1sum|tr '[:lower:]' '[:upper:]'|head -c40)
hash_head=$(printf "$your_hash"|head -c5)
hash_tail=$(printf "$your_hash"|tail -c35)
pwned_count=$(curl https://api.pwnedpasswords.com/range/${hash_head} 2> /dev/null|grep "${hash_tail}"|awk -F ':' '{print $2}')
echo "Your password has been pwned ${your_pw} times"
echo "Your password has been pwned ${pwned_count} times"
And I used as a test password 1, and this is the output:
[me@my_compuuter aaa8]$ ./was_your_password_pwned.sh
Input your password:
Your password has been pwned 1 times
timesassword has been pwned 197972
Notice how when I echo "Your password has been pwned ${your_pw} times" it gives me the correct format ($your_pw is just the password itself), but when I
echo "Your password has been pwned ${pwned_count} times" it gives me this weird format where it takes the times from the end and somehow overlaps it in the beginning... I have no clue what's going on...
Can somebody figure it out?

The list returned by that site has lines terminated by CR/LF. A CR (r) will move the caret/cursor to the beginning of the line:
printf 'good r times'
times

Wow thanks! I just added|tr 'r' 'n'to the end of thepwned_countvariable and now it works properly, thanks!

@user323587,tr -d 'r'would be more common, it actually removes the carriage return. Changing it to a newline of course works in your case, too, since the command substitution removes all trailing newlines.
