Ragazzi, questa mattina mi era nata l'esigenza di raccogliere tutte le variabili USE che ho utilizzato nel sistema durante la compilazione di tutti i miei pacchetti. Non so se può servire anche a voi, ma per me è molto utile e quindi vi passo il mio piccolo script scritto in perl.

calc-use.pl
Code:
#!/usr/bin/perl

print "Ricerca degli USE utilizzati nei pacchetti...";
@USES = `cat /var/db/pkg/*/*/USE`;
chop(@USES);
print "fatto.\n";
print "Generazione elenco USE...\n";
foreach $USES (@USES) {
  $USEJ = $USEJ." ".$USES;
}
@UX = split(/ /, $USEJ);
$count = scalar @UX;
$i=-1;
for ($j=0; $j<$count; $j++) {
  $equal = 0;
  for ($x=0; $x<=$i; $x++) {
    if (@UU[$x] eq @UX[$j]) {
      $equal = 1;
      $x = $i;
    }
  }
  if ($equal == 0) {
    $i++;
    @UU[$i] = @UX[$j];
  }
  print "\b\b\b\b\b";
  print int(($j/$count)*100);
  print " %";
}
print "\b\b\b\b\b\b";
print "100 %\n";
print "USE Utilizzate: ";
for ($z=0; $z<=$i; $z++) {
  print @UU[$z];
  print " ";
}
print "\n";


Il risultato del funzionamento di questo script è tipo questo:
Code:
localhost ~ # ./calc-use.pl
Ricerca degli USE utilizzati nei pacchetti...fatto.
Generazione elenco USE...
100 %

Spero che vi possa servire in qualsiasi modo, fatemi sapere. Un saluto a tutti ;)

Non e' la stessa cosa fare
Code:
$ emerge --info | grep USE

Tra: emerge --info | grep USE
Code:
USE="x86 X aac alsa apm avi berkdb bitmap-fonts crypt cups dvd dvdread eds emboss encode foomaticdb fortran gdbm gif gpm gstreamer gtk gtk2 imlib ipv6 jpeg libg++ libwww mad mikmod motif mp3 mpeg ncurses nls nptl nvidia ogg oggvorbis opengl oss pam pdflib perl png python quicktime readline sdl spell ssl tcpd truetype truetype-fonts type1-fonts vorbis win32codecs xinerama xml2 xmms xv xvid zlib elibc_glibc kernel_linux linguas_it userland_GNU"

e: ./calc-use.pl
Code:
USE Utilizzate:  x86 X alsa apm avi berkdb bitmap-fonts crypt cups eds emboss encode foomaticdb fortran gdbm gif gpm gstreamer gtk gtk2 imlib ipv6 jpeg libg++ libwww mad mikmod motif mp3 mpeg ncurses nls ogg oggvorbis opengl oss pam pdflib perl png python quicktime readline sdl spell ssl tcpd truetype truetype-fonts type1-fonts vorbis xinerama xml2 xmms xv zlib elibc_glibc input_devices_keyboard input_devices_joystick input_devices_mouse kernel_linux linguas_it userland_GNU video_cards_nvidia video_cards_vesa video_cards_vga aac dvd dvdread nvidia win32codecs xvid audiofile bzip2 cdb exif expat fam glut imagemagick pcre tcltk tiff udev arts gnome kde mmx qt sse cdr curl ffmpeg gtkhtml idn java junit lcms mhash mng mysql recode scanner usb esd gmp guile nptl cdparanoia esd* tga ~x86

io vedo un po' di differenza. Può darsi mi sbaglio fatemi sapere :S

Che risultato ti da questo comando:

Code:

 diff <(cat /var/db/pkg/*/*/USE | sed -e "s/\ /\n/g" | sort | uniq)  <(emerge info | grep USE | sed -e "s/USE=\"//g" -e "s/\"//g" -e "s/\ /\n/g" | sort)


?

Posteresti per favore anche il contenuto di /etc/portage/package.use.

Credo che il metodo di anacleto riporti anche le use abilitate per i singoli pacchetti. Il tuo metodo (molto comodo ;-)) mi dice invece quelle abilitate per tutti i pacchetti.

Ti riferisci a quelle contenute in /etc/portage/package.use ?

Il mio /etc/portage/package.use è vuoto.

diff <(cat /var/db/pkg/*/*/USE | sed -e "s/\ /\n/g" | sort | uniq) <(emerge info | grep USE | sed -e "s/USE=\"//g" -e "s/\"//g" -e "s/\ /\n/g" | sort) da come risultato:
Code:
4,5d3
< arts
< audiofile
9,12d6
< bzip2
< cdb
< cdparanoia
< cdr
15d8
< curl
22,27d14

< esd*
< exif
< expat
< fam
< ffmpeg

96,97d56
< udev
< usb
99,101d57
< video_cards_nvidia
< video_cards_vesa
< video_cards_vga
106d61
< ~x86

Comunque l'intento del mio script era quello di restituire TUTTI gli USE abilitati da tutti i pacchetti del sistema e quindi dentro /var/db/pkg/ (come ha ben detto codadilupo 8) )

Se lanci un:

Code:
emerge -DuNa world


cosa ti vuole rivcompilare?

E' probabile che tu abbia cambiato le USE ed alcuni pacchetti debbano essere ricompilati con le nuove USE.
