It would help to know what Operating System and Shell you have.

Many versions of "ping" default to "continuous ping" and never finish.
In my version the parameter "-n 3" will try three times, yours may be different.
Shell code is for most Bourne-like shells such as: sh, ksh, bash and Posix. Some would replace "cat" with an inward redirect if that shell will allow it.

cat link.csv|awk -F, '{print $1,$2}'|while read url title
do
        echo "Pinging ${title}"
        ping "${url}" -n 3
done
3 
#!/bin/bash

linecount=$(sed -n '$=' link.csv)
i=1
while [ $(( linecount -= 1 )) -gt -1 ] ; do
 echo "pinging `sed -n "$i s/.*[^,],//p" link.csv`"
  ping `sed -n "$i s/,.*//p" link.csv`
((i++))
  done
