Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Nice! You can avoid eval:


$(eval echo {0..${#n}})


$(seq 0 ${#n})

i like it but eval is POSIX and seq is not, that is why i chose it

Comment by SQUIIDUX 226 weeks and 4 days ago

may I suggest the following

1. replace curl with wget

2. use awk for parsing

3. use a stop condition

while [ ! -e /tmp/nt_stop ];do n=$(wget -q -O - http://news.yahoo.com/rss/|awk 'BEGIN{FS="<item><title>"}{for(i=2;i<=NF;i++){sub(/<.*/," ",$i);printf("%s",$i)}}');for i in $(eval echo {0..${#n}});do echo -ne "\e[s\e[0;0H${n:$i:$((COLUMNS - 1))}\e[u";sleep .10;[ -e /tmp/nt_stop ] && break;done;done &

to stop it

touch /tmp/nt_stop;sleep .5;rm /tmp/nt_stop

If the command is running in the background, you can just use the fg command to bring it forward and then CTRL+C to stop it or you can view the process when it gets forked and kill -9 $PID. this way there is no temp files.
