#!/usr/bin/env pythonimport tarfile,systry:    tar=tarfile.open(sys.argv[1],'r:tar')#sys.argv[1]为执行命令时输入的第1个参数，sysargv[0]为当前执行脚本路径与脚本名称；以读的模式读取tar包，tar变量包含压缩包所有文件及其属性    selection=raw_input("Enter\n\1 to extract a file\n\2 to dispaly information on a file in the archive\n\3 to list all the files in the archive\n\n")        if selection=="1":        filename=raw_input("Enter the filename to extract: ")        tar.extract(filename)#解压某一个文件，extractall是解压所有文件，默认是解压到当前文件也可使用tar.extract(filename,path="/tmp")来指定路径    elif selection=="2":        filename=raw_input("Enter the filename to inspect: ")        for tarinfo in tar:            if tarinfo.name==filename:#对比到是想查的文件就将其打印出来，tar.getnames()获取压缩包里所有文件名称                print "\n\Filename:",tarinfo.name,"\n\    Size:",tarinfo.size,"bytes"    elif selection=="3":        print tar.list(verbose=True)#verbose=True时，相当于ls -l，为False时只例出文件名。tar.close()except:    print "There was a problem running the program"

执行结果
