N\u00e5r du henter programmer p\u00e5 dettet s\u00e5 s\u00e5 som github og andre sites, kan filerne du henter v\u00e6re pakket med rar eller zip eller ande programmer. Jeg vil her gemmen g\u00e5 rar\/unrar som er et program til at pakke data\/programmer s\u00e5 de ikke fylder s\u00e5 meget.<\/p>\n
RAR er et af de mest popul\u00e6rt v\u00e6rkt\u00f8j til at oprette og udpakke komprimerede arkivfiler (.rar). N\u00e5r vi downloader en arkivfil fra nettet, kr\u00e6vede vi et rar v\u00e6rkt\u00f8j til at udpakke dem.<\/p>\n
RAR er frit tilg\u00e6ngelig under Windows-operativsystemer til h\u00e5ndtering af komprimerede filer, men desv\u00e6rre er ikke rar-v\u00e6rkt\u00f8jet forudinstalleret under Linux-systemer.<\/p>\n
Her vil jeg vise hvordan man installerer unrar og rar kommandolinjev\u00e6rkt\u00f8jer ved hj\u00e6lp af officielle bin\u00e6re tar-filer under Linux-systemer til at \u00e5bne, udpakke, fjerne eller komprimere en arkivfil.<\/p>\n
For at installere den i ubuntu skrives.<\/p>\n
$ apt install rar unrar<\/p>\n
<\/p>\n
For at udpakke en RAR-fil i det aktuelle arbejdsmappe, skal du bare bruge f\u00f8lgende kommando med unrar e mulighed.<\/p>\n
<\/p>\n
$ unrar e tecmint.rar<\/strong>\n\nUNRAR 4.20 beta 3 freeware Copyright (c) 1993-2012 Alexander Roshal\n\nExtracting from tecmint.rar\n\nExtracting index.php OK\nExtracting index.html OK\nExtracting xyz.txt OK\nExtracting abc.txt OK\nAll OK<\/pre>\n<\/p>\n
For at \u00e5bne\/udpakke en RAR-fil i en bestemt sti eller destinationsmappe, skal du bare bruge funktionen unrar e. Den vil udtr\u00e6kke alle filerne i det specificerede destinationsmappe. som vist her.<\/p>\n
