Recientemente instale el free pascal bajando el archivo fpc-2.4.2.i386-linux.tar y descomprimiendolo tar -xvf fpc-2.4.2.i386-linux.tar para luego instalarlo en sh install.sh pero lamentablemente no consigo la forma de arranca el programa.

Free Pascal es un compilador de línea de comandos. Utiliza el comando fpc .También hay un IDE que funciona en modo texto (aunque se debe instalar por separado) con un aspecto visual muy similar al viejo -y querido- Turbo Pascal 6 y superiores (basado en la librería Turbo Vision).

Y luego está LAzarus, que más que un IDE, es un RAD completo que internamente utiliza el compilador Free Pascal.

Muy bien es el comando fpc pero aparece los siguiente:

Hola,
el comando fpc es el "Free Pascal Compiler", el cual debe ir acompañado del archivo de código fuente para compilarlo, prueba a generar un hola_mundo.pas y luego utiliza:
fpc hola_mundo.pas
con esto tendría que generarte el ejecutable el cual lo puede ejecutar así:
./hola_mundo
Ahora, si quieres abrir el IDE, creo que se llama "fp-ide", prueba y nos cuentas

Saludos

en la consola ponés: fp
