Posted by: seba in FreePascal, Linux, Programming, Windows, tags: , , ,

FreePascal is a open-source compiler which implement the pascal language,  specifically the Borland Turbo Pascal dialect and Delphi. FreePascal is available for most common operating systems, the following operating systems are supported: Linux, FreeBSD, Mac OS X/Darwin, Mac OS classic, DOS, Win32, Win64, WinCE, OS/2, Netware (libc and classic) and MorphOS. Here the advantages of programming in FreePascal; i decided to use pascal for my programs because the code is portable from linux to windows and because pascal is a very clean language.

To install freepascal in debian run, from console:

# apt-get install fp-compiler fp-units-rtl

For an introducion to language see this good tutorial: FreePasca tutorial. 

Bye Bye.

Sudo has the convenience to limiti the use of root account and to logging, both successful and unsuccessful, attempts to log file.

The syntax of sudo is:

now sudo, by default, requires that user autheticate themselves with his system password (not root password); an user is authorized to use a command if he is listed in /etc/sudoers file, but if he is unauthorized a mail is sent to root or  to user specified in config file.   To install sudo in Debian run:

# apt-get install sudo

 The configuration file of sudo is /etc/sudoers, it is editable vith the utility visudo: it open the sudoers file with your system editor and do the check of file syntax. The syntax of file sudoers

P.S.: be carefull when you configure sudo, it is a very powerful tool, that used in wrong way can damage the system.
