Bash Script to check in terminal if URLS are up or down?

Question

excuse my bad english:

This is the situation; I make my own IPTV lists taking the URLs of free sites and passing them to the smart tv, I would like to know which urls work and which ones don't to replace them, and doing it manually is an impossible task, I found the snap bash script to delete old snaps fantastic from the terminal with a single command, something like this would work for me, but OBVIOUSLY I don't know anything about scripts, bash or programming, if you could help me with a bash script that checks all the URLs of a .txt document in the terminal indicating which ones are up and which ones down I would appreciate very much, that would save me a lot of time, I appreciate your help in advance!

Answer 1

Ive tested it a couple of times, seems to work ok.

#!/bin/bash

if [ $# -eq 0 ]
then
    fin=-
else 
    fin=$1
fi

urlarr=( $(cat $fin | strings | tr ',:\/' '\n\n\n' | grep -i "\.com\|\.net\|\.edu\|\.org\|^[0-9].*\.[0-9].*\.[0-9].*\.[0-9].*" | tr '\n' ' ' )  )

for i in ${urlarr[@]}
do
  if ping -c1 -w1 $i 2>&1 >/dev/null
  then
    echo $i is up.
  else
    echo $i is down.
  fi
done

exit $?

This is the best i can do without your urls to test. If the wget part doesnt work out you can look into replacing w/ curl or ncat (nc) to test wether streams are live.

#!/bin/bash

if [ $# -eq 0 ]
then
    fin=-
else 
    fin=$1
fi

urlarr=( $(cat $fin | strings | grep '://' | grep -i "\.com\|\.net\|\.edu\|\.org\|[0-9].*\.[0-9].*\.[0-9].*\.[0-9].*" | tr '\n' ' ' )  )

for i in ${urlarr[@]}
do
  if wget -q --tries=1 --no-cache --spider -O /dev/null --ignore-length -T 1 "$i"
  then
    echo $i is good.
  else
    echo $i is bad.
  fi
done

exit $?
