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

What others think

use of command "stat" works too, eg:

stat -c%a\ %n *


stat --printf="%a\t%s\t\t%n\t\n" *

etc... (man stat for more info) depending on what you exactly want to do...

you need to change instead of "i+2" "i+1"

cuz it does not give good results.

Comment by RanyAlbeg 363 weeks and 2 days ago

Thanks for this! It's pretty much what I wanted! I can always say "I wish I can use this to see my colors in the terminal!" and other stupid bits, but I was able to do this in ~/.bash_profile:

alias lo="ls -l | awk '{k=0;for(i=0;i

Sorry for the previous, but the escapes added killed my previous comment!

In the alias I just enclosed in double quotes and then added escapes as needed, basically before the $ and other double quotes
