curl get all links of a web-page

I used to utilize following command to get all links of a web-page and then grep what I want: curl $URL 2>&1 | grep -o -E 'href="([^"#]+)"' | cut -d'"' -f2 | egrep $CMP-[0-9].[0-9].[0-9]$ | cut -d'-' -f3 It was doing great till yesterday. I tried to run curl itself and I saw it returns: % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 Was there any possible updates which causes the command not working or what? **EDIT 1:** I changed my approach to wget regarding [this answer](https://stackoverflow.com/a/2804721/1626977) : wget -q $URL -O - | grep -o -E 'href="([^"#]+)"' | cut -d'"' -f2 | egrep $CMP-[0-9].[0-9].[0-9]$ | cut -d'-' -f3 But still doesn't know why curl approach suddenly stopped working.
