Welcome (#2)!

Hi! Finally, after turning on my Drupal installation, an other important step: the international version.

The translating process will be hard to do and for sure with plenty of mistakes (please correct me! I will accept your suggestion).

You'll find from time to time external links and credits for friends that gave help in solving a problem or in finding a tool, but everybody can help using comments.

Notice that comments aren't published in real time, but usually you haven't to wait so much time to see your post published!

In order to help you in finding the last modification and new posts, there is a "Recent" block that show the date of the last modification and a flag corresponding to the language of the post. Hope you'll find it useful!

Have a nice web-surfing!

crontab -e: I can't use the default editor!

|

Usually we use crontab -e command, while logged in as a user, to modify the user's cron jobs or crontab -e -u[user] as root.

The editor used fot this depends on the system variable VISUAL or EDITOR (if present) else the default editor will be used /usr/bin/editor.

So if the default editor is a not well known program (take "VI" as an example, even if you use the more user friendly "VIM"...), you can modify the suggested system variables if present, to verify:

set | grep -iE '(visual)|(editor)'

grep, cut, awk, sort, uniq... linux shell power!

How powerful can be linux shell? This is just an other nice example of the power of linux shell!

Well, this is the game: suppose to need on a remote machine to count how many times an ip address (or user or whatever you want) is used in a log file or a part of it.

Let's take a sample log: Apache access log.

The format is something like (see attached example log file):
1.1.1.1 - - [16/Jan/2008:22:18:42 +0100] "GET /dir/pag.htm" 200 11 "http://diegobelotti.com/a.php" "Mozilla 5 (Windows..) Firefox"
