good one.

Comment by Habitual 201 weeks and 6 days ago

Could you explain the command ? I pasted it on my bash terminal, nothing happened.

Comment by ankush108 201 weeks and 1 day ago

after pasting the above command, enter:

hourglass $int

where $int can be any positive integer.

Comment by capncanuck 201 weeks and 1 day ago

I wouldn't call that an "hourglass". I'd call it a "spinner". In Bash and some others which support [[ ]], use this: while (( $SECONDS < s )). You only need one echo if you use a carriage return: echo -en "$f\r"; sleep .2s and you don't really need the double ampersands. Add RETURN to your trap and you won't need the extra tput at the end.

Awesome advice unixmonkey.. Everything you suggested worked other than the only one echo... the \b in the second echo is what backspaces the first char
