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

This command, when run from the directory containing "filename", will remove the file and any hard or symbolic links to the file.

This is a slight variation of an existing submission, but uses regular expression to look for files instead. This makes it vastly more versatile, and one can easily verify the files to be kept by running ls | egrep "[REGULAR EXPRESSION]"

TABLE_NAME=YYZ ; for DATABASE in $(echo "SELECT TABLE_SCHEMA FROM information_schema.tables WHERE TABLE_NAME='$TABLE_NAME'" | mysql -N) ; do echo -n "$DATABASE: " ; echo "SELECT COUNT(*) FROM $TABLE_NAME" | mysql $DATABASE -N ; done | fgrep -v ': 0'

Pulls all instances of table out of information schema, executes a SELECT COUNT(*) on each table/database instance, and then strips out any empty tables.

This will give you a friendly warning if a command doesn't exists.

while true; do nc -z localhost 3333 >|/dev/null || (ssh -NfL 3333:REMOTE_HOST:5432 [email protected]_HOST); sleep 15; done

Check if SSH tunnel is open and open it, if it isn't.

NB: In this example, 3333 would be your local port, 5432 the remote port (which is, afaik, usually used by PostgreSQL) and of course you should replace REMOTE_HOST with any valid IP or hostname. The example above let's you work on remote PostgreSQL databases from your local shell, like this:

psql -E -h localhost -p 3333
wget -r --no-parent http://codeigniter.com/user_guide/ ; mv codeigniter.com/user_guide/* . ; rm -rf codeigniter.com

I constantly need to work on my local computer, thus I need a way to download the codeigniter user guide, this is the wget way I figured.

This will delete the branch 'featureless' on the origin remote.

Do not forget to delete the branch locally using:

git branch -d featureless

If there is update available for the package you can see upgrade is from which version to which version. Also you will get detail about which release the package belongs to (stable/testing/sid).

Using sed to print newlines as doing it in one line with diff is non-trivial.
