la mia domanda farà sorridere molti di voi, ma come si fa a scompattare questi file compressi?
Ti consiglio la lettura di http://www.fedoraonline.it/modules/smartsection/item.php?itemid=26 in merito alle estensioni tar.gz, bz2 e tgz. 
Ciao
Se non vi dispiace ci aggiorniamo
In che senso?
Per il bz2 ti sposti nella cartella dove hai salvato il file e dai:
$ tar -xvjf programma-x.y.z.bz2E’ anche possibile sfruttare nei sistemi multi-cpu/multicores la potenza del parallelismo con per esempio pbzip2 soprattutto dovesse trattarsi di compressione/decompressione di files di grosse dimensioni.
In questo caso, riferendoci ai files .bz2 si può sfruttare previo
# yum install pbzip2Quindi, nel caso di dover estrarre un archivio di tipo tar.b22 (tbz2), potremo fare:
$ pbunzip2 archivio_compresso.tar.bz2
Otterremo il file archivio_compresso.tar
Infine
$ tar -xvf archivio_compresso.tar
Et voilà 
Il problema è che non riesco a spostarmi nella cartella dove ho salvato il file.
Per meglio farmi capire il file da scompattare è nella directory home, all’interno di scaricati
Ha fatto mote prove ma non sono mai riuscito.
Pensavo che la soluzione fosse
[piero@piero ~]$ cd /home/piero/scaricati
bash: cd: /home/piero/scaricati: No such file or directory
potreste aiutare questo imbranato?
se sei loggato come utente semplice (e mi pare proprio il tuo caso) basta scrivere
cd Scaricati
se, invece, sei utente root devi fare:
- cd …
- cd home/piero/scaricati
Ovviamente fai attenzione a lettere maiuscole/minuscole e cose de genere. Scusami per l’ovvietà ma è meglio essere chiari quando è possibile.
Sei stato di grandissimo aiuto.
Ho capito che in realtà il mio era un errore di battitura (minuscola invece di maiuscola…punto invece di trattino).
Grazie ancora.
A questo punto procedo con l’installazione ma mi blocco con il pacchetto sox
[piero@piero ~]$ cd Scaricati
[piero@piero Scaricati]$ tar -xvjf imagination-2.1.1.tar.bz2

NOTE FOR PACKAGERS:
Before packaging Imagination (unless this hasn’t already been done) please
comment line 22 in file src/support.c from this:
#define PLUGINS_INSTALLED 0
to this:
#define PLUGINS_INSTALLED 1
If you fail to do so Imagination won’t be able to load the transitions and the
transition’s images when the package is installed.
Girando per il web ho trovato http://dnmouse.org/forum/viewtopic.php?f=3&t=2197&sid=394b367bd2a5716e0cb328bba49114d6. Troverai anche il pacchetto rpm di questo programma, se riesci ad istallare con rpm è meglio (consiglio dato da virus in passato 
Inoltre, se compili tu, esegui quella modifica al file support.c perché serve ad abilitare le transizioni o qualcosa di simile.
grande!!!
Finalmente ho installato il rpogramma che volevo.
