What Others Think

Nice! You can avoid eval: Replace $(eval echo {0..${#n}}) with $(seq 0 ${#n})

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

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.
