LinuxQuestions.org - Bash stock quotes with curl

Hi,

I am trying to write a script that I will allow to run continually monitoring stock quotes sourced from yahoo finance.

My problem is how to compare prices each time they are retrieved so I can format them appropriately, e.g. red text for decrease in price green text for increase/no-change.

My code so far:

Code:

#/bin/bash



while x=0; do  

val=`curl -s http://download.finance.yahoo.com/d/quotes.csv?\s\=BARC.L\&\f\=l1`

echo -e "\033[32m$val\033[0m";

val2=`curl -s http://download.finance.yahoo.com/d/quotes.csv?\s\=BARC.L\&\f\=l1`

if [ $val2 -lt $val ]; then

  #prints in red indicating price fall

  echo -e "\033[33m$val2\033[0m";

fi

sleep 5;

done

I would appreciate some input.

Thanks
