Der var en som spurgte mig om det ikke er muligt at udf\u00f8re samme kommando p\u00e5 mod flere servere uden jeg skal login p\u00e5 hver maskine on udf\u00f8re nogle kommandoer.<\/p>\n

hvis nu jeg har en liste med ip adresser eller hostnavne hvordan kan jeg s\u00e5 g\u00f8re.<\/p>\n

S\u00e5 den nemme l\u00f8sning er at inds\u00e6tte listen i en fil f\u00f8rst med en editor som vi. Derefter kan du skrive.<\/p>\n
$ for in $f(cat serverlist.txt); do ssh bruger@f$ 'ls'; done<\/pre>\n
hvis du har brug for at angive porten kan du skrive.<\/p>\n
$ for in $f(cat serverlist.txt); do ssh -p 2222 bruger@f$ 'ls'; done\n\n<\/pre>\n
I dette eksempel skal du huske at \u00e6ndre “bruger” til det rigtige bruger navn. Med denne metode virker det bedst uden brug af password, men med ssh keys, som jeg vil forklare om i en anden guide.<\/p>\n
