Site originally by David Winterbottom (user root).

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

Most used commands from history (without perl)

I copied this (let's be honest) somewhere on internet and I just made it as a function ready to be used as alias. It shows the 10 most used commands from history. This seems to be just another "most used commands from history", but hey.. this is a function!!! :D

Show complete URL in netstat output

The -W switch of netstat makes it print complete URL of the connections, which otherwise by default

is truncated to fit its default column size.

Now to compensate for irregular column sizes, pipe the output to column (-t switch of column prints in tabular form). The only downside to this part is that the very first row, the header, goes pear shape.

Check if you partition are aligned

To get most of you HDD/SSD driver you need to make sure you partition are aligned, if not the speed penalty can be up to 50% slower!

this simple one liner will check to see if each partition start sector is divided by 512

you need to change sda with your driver

if you find the one of your partitions is not aligned use gparted to move the start sector of the partition to be divided of 512

Just an alternative with more advanced formating for readability purpose. It now uses colors (too much for me but it's a kind of proof-of-concept), and adjust columns.

-n switch keeps empty columns

If your distribution does not ship with a recent column version that supports -n you can use this alternative:

perl -pe 's/(^|;);/$1 ;/g' file.csv | column -ts\; | less -S

Change the delimiter to your liking.
