Merci beaucoup.
Merci beaucoup.
J'ai déjà eu ce sentiment : "Le choc est d’autant plus grand quand nous devons utiliser l’ordinateur de quelqu’un d’autre."

Site qui permet de contruire sa propre ligne de commande pour 7z (7zip).
Exemple :

--> STORE ONLY + protection par password + cryptage des noms de fichier

Comment inverser des lignes sous vim ?
:g/^/m0
: start command-line mode.
g means you'll take an action on any lines where a regular expression matches
/ begins the regular expression (could have used any valid delimiter)
^ matches the start of a line (which matches all lines in the buffer)
the second / ends the regular expression; the rest is an Ex command to execute on all matched lines (i.e. all lines in buffer)
m means move (:help :move)
0 is the destination line (beginning of buffer)
:g/^/m0
: start command-line mode.

PB "lftp Erreur fatale: Certificate verification: Not trusted"
---------- ---------- ---------- ---------- ---------- ----------
SOLUTION 1) no certificate check
---------- ---------- ---------- ---------- ---------- ----------
echo "set ssl:verify-certificate no" >> ~/.lftp/rc
will solve the problem if you dont want the certificate to be checked
SOLUTION 2) The secure solution with certificate is
---------- ---------- ---------- ---------- ---------- ----------
What worked for me step by step with lftp:
get certificate of host with openssl s_client -connect <ftp_hostname>:21 -starttls ftp, at the begining of result I got something like -----BEGIN CERTIFICATE-----
MIIEQzCCAyu.....XjMO
-----END CERTIFICATE-----
copy that -----BEGIN CERTIFICATE-----
MIIEQzCCAyu.....XjMO
-----END CERTIFICATE----- into /etc/ssl/certs/ca-certificates.crt
Into lftp configuration reference this certificate file adding to /etc/lftp.conf for systemwide set ssl:ca-file "/etc/ssl/certs/ca-certificates.crt"
and then do your sync or whatever with lftp, on my case it is lftp -u "${FTP_USER},${FTP_PWD}" ${FTP_HOST} -e "set net:timeout 10;mirror ${EXCLUDES} -R ${LOCAL_SOURCE_PATH} ${REMOTE_DEST_PATH} ; quit"

Après réinstallation de VIM (version 8) sur un PC Windows (PRO), à chaque ouverture de fichier, VIM me faisait un :
set textwidth=78
malgré un
set textwidth=0
dans mon "_gvimrc"
*Solution*
Faire un
verbose set tw?
Qui permet de savoir dans quel fichier et à quelle ligne l'écriture de cette valeur s'est effectuée.
Pour moi c'était un
autocmd FileType text setlocal textwidth=78
dans un fichier _vimrc dans le répertoire d'install de VIM. Grrr !
J'ai donc rajouter un :
autocmd FileType text setlocal textwidth=0
dans mon _gvimrc.
*Conclusion*
- VIM est toujours parfait (ou presque)
- Merci Internet (encore) pour cette solution
Si cela peut aider...

1. MUST This word, or the terms "REQUIRED" or "SHALL", mean that the
definition is an absolute requirement of the specification.
2. MUST NOT This phrase, or the phrase "SHALL NOT", mean that the
definition is an absolute prohibition of the specification.
3. SHOULD This word, or the adjective "RECOMMENDED", mean that there
may exist valid reasons in particular circumstances to ignore a
particular item, but the full implications must be understood and
carefully weighed before choosing a different course.
4. SHOULD NOT This phrase, or the phrase "NOT RECOMMENDED" mean that
there may exist valid reasons in particular circumstances when the
particular behavior is acceptable or even useful, but the full
implications should be understood and the case carefully weighed
before implementing any behavior described with this label.
5. MAY This word, or the adjective "OPTIONAL", mean that an item is
truly optional. One vendor may choose to include the item because a
particular marketplace requires it or because the vendor feels that
it enhances the product while another vendor may omit the same item.

prepared to interoperate with another implementation which does
include the option, though perhaps with reduced functionality. In the
