Stai utilizzando Windows XP, quindi dovresti avere Windows Scripting Host installato per impostazione predefinita. Detto questo, ecco uno script WSH JScript per fare ciò di cui hai bisogno. Basta copiare il codice su un nome file xtract.bat o qualcosa del genere (può essere qualsiasi cosa purché abbia l'estensione .bat
) ed eseguire:
xtract.bat example.tar.gz
Per impostazione predefinita, lo script controlla la cartella dello script, nonché la PATH
variabile di ambiente del sistema per 7z.exe. Se vuoi cambiare il modo in cui cerca qualcosa, puoi cambiare la variabile SevenZipExe nella parte superiore dello script in qualunque cosa tu voglia che sia il nome dell'eseguibile. (Ad esempio, 7za.exe o 7z-real.exe) È inoltre possibile impostare una directory predefinita per l'eseguibile modificando SevenZipDir. Quindi se 7z.exe
è a C:\Windows\system32\7z.exe
, dovresti mettere:
var SevenZipDir = "C:\\Windows\\system32";
Comunque, ecco lo script:
@set @junk=1 /* vim:set ft=javascript:
@echo off
cscript //nologo //e:jscript "%~dpn0.bat" %*
goto :eof
*/
/* Settings */
var SevenZipDir = undefined;
var SevenZipExe = "7z.exe";
var ArchiveExts = ["zip", "tar", "gz", "bzip", "bz", "tgz", "z", "7z", "bz2", "rar"]
