Show key fingerprints of public keys in .ssh/authorized_keys file

gistfile1.sh

#!/bin/bash

( while read L
  do echo $L > /tmp/pubkey
  printf "%-16s => " $(cut -f 3 -d ' ' /tmp/pubkey)
  ssh-keygen -l -f /tmp/pubkey
  done
  rm /tmp/pubkey
) < .ssh/authorized_keys

I have some comments & blank lines in my authorized_keys file, so I added a check to ignore those.

#!/bin/bash
IGNORE_LINES="^#|^$"

( while read line
do echo $line> /tmp/pubkey
    if [[ "$line" =~ $IGNORE_LINES ]]
    then
        continue
    fi
    printf "%-16s => " $(cut -f 3 -d ' ' /tmp/pubkey)
    ssh-keygen -l -f /tmp/pubkey
done
rm /tmp/pubkey
) < $HOME/.ssh/authorized_keys

Thanks!
