J’explique tr\u00e8s succintement quelques commandes majeures de cet outil qui permet de \u00ab\u00a0d\u00e9tacher des sessions shell du terminal o\u00f9 vous les avez lanc\u00e9es\u00a0\u00bb.
\nEn clair : lorsque vous avez des outils en mode texte sur lesquels vous devez pouvoir revenir \u00e0 distance et plus tard, vous lancez vos commandes dans un \u00ab\u00a0screen\u00a0\u00bb et lorsque vous fermez votre terminal (session putty distante, locale dans un xterm etc), la session reste stock\u00e9e quelque part et vous pourrez la reprendre de mani\u00e8re interactive (clavier) plus tard.
\n<\/p>\n

C’est pratique pour g\u00e9rer de lourds transferts FTP en mode texte (genre lftp) et surtout – dans mon cas – pour g\u00e9rer mes serveurs de jeux online \ud83d\ude09
\nJe vais bient\u00f4t poster 2\/3 articles sur la mise en place de quelques serveurs de jeux online et \u00ab\u00a0screen\u00a0\u00bb est un outil indispensable.<\/p>\n

Le principe de base :
\nVous lancez une session en lui donnant un nom :<\/p>\n

screen -S ma_session<\/pre>\n
On ne le remarque pas trop quand on n’est pas habitu\u00e9, mais \u00e7a ouvre un autre shell.
\nVous faites ce que vous avez \u00e0 faire dedans, ici on va se limiter \u00e0 une commande ls<\/code> histoire de faire afficher quelque chose.
\nPuis vous \u00ab\u00a0d\u00e9tacher\u00a0\u00bb la session gr\u00e2ce \u00e0 la combinaison de touches CTRL-A puis D (sans l\u00e2cher CTRL).
\nCa vous sort de la session et vous voyez le mot :<\/p>\n
[detached]<\/pre>\n
Vous pouvez alors lister vos sessions :<\/p>\n
screen -ls\r\nThere are screens on:\r\n        20850.ma_session        (Detached)\r\n1 Socket in \/var\/run\/screen\/S-toto.<\/pre>\n
Les num\u00e9ros sont les PID des shells correspondant \u00e0 votre session.<\/p>\n
Pour reprendre une session (on va nettoyer l’\u00e9cran pour bien se rendre compte : commande clear<\/code>)<\/p>\n
screen -r ma_session<\/pre>\n
Et l\u00e0 vous retrouvez votre session de toute \u00e0 l’heure, avec le contenu du ls<\/code>.<\/p>\n
Ok ? principe pig\u00e9 ?<\/p>\n
Documentez-vous sur le param\u00e8tre \u00ab\u00a0-x\u00a0\u00bb, il est terrible celui-l\u00e0 ainsi que sur la combo de touches \u00e0 faire pour pouvoir remonter dans l’historique de la session, \u00e0 base de CTRL-A + Esc + CTRL-U ou D. Enfin bref, je ne m’en souviens jamais \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
