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
while [ true ]; do head -n 100 /dev/urandom; sleep .1; done | hexdump -C | grep "ca fe"

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

Not as taxing on the CPU.

Alternatives

There are 8 alternatives - vote for the best!

Terminal - Alternatives
cat /dev/urandom | hexdump -C | grep "ca fe"
2010-09-27 08:20:44
User: BOYPT
Functions: cat grep hexdump
38

just make some data scrolling off the terminal. wow.

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
2010-10-08 12:12:00
User: houghi
Functions: echo seq sleep
15

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.

for i in `seq 0 100`;do timeout 6 dialog --gauge "Install..." 6 40 "$i";done
2010-09-28 06:38:20
User: javisol
11

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
2010-10-05 02:29:23
User: dennisw
Functions: echo sleep
10

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.

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

Thanks, nowhere near as taxing went from 90% cpu from hexdump to 10% can actually compile and do other tasks while on that coffee break now
