Hello,   Oui, c'est tout à fait possible. Il suffit de modifier la liste des dépot, remplacer 19.04 par 20.04 et mettre à jour.   Ça se fait dans le fichier /etc/apt/sources.l

Oui mais :

fabien@Interceptor ~ $ ls
--help

fabien@Interceptor ~ $ ls -lh --help
Usage: ls [OPTION]... [FILE]...
List information about the FILEs (the current directory by default).
Sort entries alphabetically if none of -cftuSUX nor --sort.

Mandatory arguments to long options are mandatory for short options too.
 -a, --all				  do not ignore entries starting with .
 -A, --almost-all		   do not list implied . and ..
  --author			   with -l, print the author of each file
 -b, --escape			   print octal escapes for nongraphic characters
  --block-size=SIZE	  use SIZE-byte blocks
 -B, --ignore-backups	   do not list implied entries ending with ~
 -c						 with -lt: sort by, and show, ctime (time of last
						   modification of file status information)
						   with -l: show ctime and sort by name
						   otherwise: sort by ctime
 -C						 list entries by columns
  --color[=WHEN]		 control whether color is used to distinguish file
						   types.  WHEN may be `never', `always', or `auto'
 -d, --directory			list directory entries instead of contents,
						   and do not dereference symbolic links
 -D, --dired				generate output designed for Emacs' dired mode
 -f						 do not sort, enable -aU, disable -lst
 -F, --classify			 append indicator (one of */=>@|) to entries
  --file-type			likewise, except do not append `*'
  --format=WORD		  across -x, commas -m, horizontal -x, long -l,
						   single-column -1, verbose -l, vertical -C
  --full-time			like -l --time-style=full-iso
 -g						 like -l, but do not list owner
 -G, --no-group			 like -l, but do not list group
 -h, --human-readable	   with -l, print sizes in human readable format
						   (e.g., 1K 234M 2G)
  --si				   likewise, but use powers of 1000 not 1024
 -H, --dereference-command-line
						 follow symbolic links listed on the command line
  --dereference-command-line-symlink-to-dir
						 follow each command line symbolic link
						 that points to a directory
  --hide=PATTERN		 do not list implied entries matching shell PATTERN
						   (overridden by -a or -A)
  --indicator-style=WORD append indicator with style WORD to entry names:
						   none (default), slash (-p),
						   file-type (--file-type), classify (-F)
 -i, --inode				with -l, print the index number of each file
 -I, --ignore=PATTERN	   do not list implied entries matching shell PATTERN
 -k						 like --block-size=1K
 -l						 use a long listing format
 -L, --dereference		  when showing file information for a symbolic
						   link, show information for the file the link
						   references rather than for the link itself
 -m						 fill width with a comma separated list of entries
 -n, --numeric-uid-gid	  like -l, but list numeric user and group IDs
 -N, --literal			  print raw entry names (don't treat e.g. control
						   characters specially)
 -o						 like -l, but do not list group information
 -p, --indicator-style=slash
						 append / indicator to directories
 -q, --hide-control-chars   print ? instead of non graphic characters
  --show-control-chars   show non graphic characters as-is (default
						 unless program is `ls' and output is a terminal)
 -Q, --quote-name		   enclose entry names in double quotes
  --quoting-style=WORD   use quoting style WORD for entry names:
						   literal, locale, shell, shell-always, c, escape
 -r, --reverse			  reverse order while sorting
 -R, --recursive			list subdirectories recursively
 -s, --size				 with -l, print size of each file, in blocks
 -S						 sort by file size
  --sort=WORD			extension -X, none -U, size -S, time -t,
						 version -v, status -c, time -t, atime -u,
						 access -u, use -u
  --time=WORD			with -l, show time as WORD instead of modification
						 time: atime, access, use, ctime or status; use
						 specified time as sort key if --sort=time
  --time-style=STYLE	 with -l, show times using style STYLE:
						 full-iso, long-iso, iso, locale, +FORMAT.
						 FORMAT is interpreted like `date'; if FORMAT is
						 FORMAT1<newline>FORMAT2, FORMAT1 applies to
						 non-recent files and FORMAT2 to recent files;
						 if STYLE is prefixed with `posix-', STYLE
						 takes effect only outside the POSIX locale
 -t						 sort by modification time
 -T, --tabsize=COLS		 assume tab stops at each COLS instead of 8
 -u						 with -lt: sort by, and show, access time
						   with -l: show access time and sort by name
						   otherwise: sort by access time
 -U						 do not sort; list entries in directory order
 -v						 sort by version
 -w, --width=COLS		   assume screen width instead of current value
 -x						 list entries by lines instead of by columns
 -X						 sort alphabetically by entry extension
 -1						 list one file per line
  --help	 display this help and exit
  --version  output version information and exit

SIZE may be (or may be an integer optionally followed by) one of following:
kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.

By default, color is not used to distinguish types of files.  That is
equivalent to using --color=none.  Using the --color option without the
optional WHEN argument is equivalent to using --color=always.  With
--color=auto, color codes are output only if standard output is connected
to a terminal (tty).  The environment variable LS_COLORS can influence the
colors, and can be set easily by the dircolors command.

Exit status is 0 if OK, 1 if minor problems, 2 if serious trouble.

Report bugs to <bug-coreutils@gnu.org>.

Donc il ne faut pas appeler un fichier "--help" lol

bon, petit à petit mon script devient moins petit....

mais nouveau problème....

c'est possible de récupérer facilement un nom de fichier sans extesionà partir du nom de fichier complet

il y a bien basename, mais ca suppose qu'on connait l'extension... or , vu comment j'ai commencé le script, je ne connais pas à priori l'extension.

je sais pas si je suis très clair....

heu, non pas trop....

sinon, ça y est la loi est passée. Je pense que vu comment s'est passé toute cette histoire, le conseil constitutionnel ne changera pas grand chose.

Bref, notre illégalité se rapproche à grand pas :francais:

ben, je désobéirai civiquement alors....

basename ca marche comme ca :

basename nomfichier.ext '.ext'

et ca renvoie nomfichier (ce que je cherche à récupérer)

le probleme c'est que je connais nomfichier.ext mais pas .ext

la facon bourine serait d'envisager toutes les extensions possibles, mais je me demande s'il n'y a pas un peut plus intelligent :yes:

Avec une expression rationnelle ça se fait bien :

#!/bin/sh

delext()
{
echo "$1" | sed -r -e 's/\.[^.]+$//g'
}

for fichier in *
do
delext $fichier
done

demonstration :

 $ ls
a.b.c.d  a.txt  b.log  c.avi  delext.sh  K.mkv  plop  test.
$ ./delext.sh
a.b.c
a
b
c
delext
K
plop
test.

Duke, tu serais pas mieux de faire une truc avec awk ?

Genre définir le point comme séparateur et prendre que le premier bout ?

Jvais essayer.

edit :

┌─(17:58:39)-(nonas@gentop)-(~/test)──
└─> $ ls
toto.foo
┌─(17:59:12)-(nonas@gentop)-(~/test)──
└─> $ ls | awk -F . {'print $1'}
toto

Duke98 m'a parlé sur le chan d'un problème quand le fichier commence par un point (genre .test ou ./.test)

J'avais même pas envisagé cette possibilité (franchement c'est n'importe quoi ce que je fais...)

Bon voilà l'expression rationnelle modifiée :

s/([^/]+)\.[^.]+$/\1/g

Et le test :

 $ ./delext.sh .test ./.test .test.avi ./.test.avi a.b.c.d c.avi test.
.test
./.test
.test
./.test
a.b.c
c
test.

Je viens de remarquer sur le site un truc qui me dérenger. Depuis que j'ai réinstaller Debian ce matin, la police du forum n'est plus la même qu'avant. Elle est devenue très désagréable...

De quoi cela vient-il ? :francais:
