Hi All,


my intention is read urls from a file (what ever url's it may be) but the url's which are not opening i.e which displays 404 , page not found error and so on should be commented in the file with # symbol.


for the correct url's : nothing to be done(except script should validate whether the url is working or not)

for the wrong urls's : script should place a # symbol infront of the url in a file
example: # http://yahoommail.com/


Kindly help me out with a script...... pls
