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?

@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.

Note use of CRLF line endings is common in Internet protocols, and in particular is required for content-type: text/plain in MIME (email, or news), see rfc2046 section 4.1.1. It not clear all MIME requirements should (or sometimes can) carry over to HTTP, but it is best to assume they do when there is no statement or clear evidence otherwise.
