Functions

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

pretend to be busy in office to enjoy a cup of coffee

Terminal - pretend to be busy in office to enjoy a cup of coffee
j=0;while true; do let j=$j+1; for i in $(seq 0 20 100); do echo $i;sleep 1; done | dialog --gauge "Install part $j : `sed $(perl -e "print int rand(99999)")"q;d" /usr/share/dict/words`" 6 40;done

pretend to be busy in office to enjoy a cup of coffee

This will turn it in an infinite loop and also shows random words from a file, so it won't be the same each time and also not just a number.

Alternatives

There are 3 alternatives - vote for the best!

Terminal - Alternatives
cat /dev/urandom | hexdump -C | grep "ca fe"

just make some data scrolling off the terminal. wow.

for i in `seq 0 100`;do timeout 6 dialog --gauge "Install..." 6 40 "$i";done

The first parameter after timeout is the key parameter; number of seconds to wait. With a 6 you have 600 seconds for your coffee break (10min).

for i in {0..600}; do echo $i; sleep 1; done | dialog --gauge "Install..." 6 40

Dialog's gauge widget accepts progress updates on stdin. This version runs dialog once and updates it every second.

There's no need to use timeout which causes screen flicker since it restarts dialog for each update.

while [ true ]; do head -n 100 /dev/urandom; sleep .1; done | hexdump -C | grep "ca fe"
export GREP_COLOR='1;32'; cat /dev/urandom | hexdump -C | grep --color=auto "ca fe"

Know a better way?

If you can do better, submit your command here.

What others think

Not really sure why you need sed and Perl here. You could make use of $RANDOM instead:

sed -n $(( $RANDOM * 3 ))p /usr/share/dict/words

I multiplied by 3 since the limit of that variable is 32k.

It would also be easy to do the whole radom-word-choice operation in a Perl one-liner.
