Check the Re-create Folders box to restore thefolder (Apache web server)
Check the Re-create Folders box to restore thefolder structure. We ve never encountered a case where we didn twant to re-create folders. If you don tselect the Re-create Folders check box, all the subdirectories and their contents end up in your current directory. Cleaning up theunpacked pile of structureless files wastes time. 5.Check the Overwrite Existing Files box toreplace any file with a duplicate name in yourfolder. 6.Check the Do Not Extract Older Files box topreserve the most recent copy of the file. If the copy on your computer is more currentthan the archived copy, the older file is notextracted. This option works only if theOverwrite Existing Files option is checked. 7.Check the View Destination Folder AfterExtraction box to open a file manager windowwith your newly unpacked archive. 8.When you re ready, click OK to unpack thefile(s). If the destination folder doesn t already exist, File Roller asks if you want to create it. Inspect suspicious-looking files that areincluded in a tarball before unpacking it. To doso, right-click the filename and choose ViewFile from the drop-down menu to display thefile s contents. If the file looks questionable, don t open it! Adding Functionality to tar with Complex CommandsThe File Roller enables you to quickly and easilybuild or unpack archives, but sometimes using thecommand line with the tarcommand is the way togo. The following sections explain how combiningthe tarcommand with other functions can give youextra power when you need it. Building archives from the command lineYou can build simple archives (containing one file ormany) with the tarcommand. Here is a basic tarcommand to create a gzip-compressed archive: $ tar -zcvf archivename filestoarchiveIf you want to archive multiple files, just list them atthe end of the command line (separate the nameswith a space character). Compressing an archive increases the time ittakes to create the archive. If you don t needto transfer the file over the Web or if the datais already compressed (such as RPMs), skip the-zor -joptions when you create the archive. tarhas a lot of powerful options, the most useful ofwhich are listed in Table 13-1. TABLE13-1: USEFULTAROPTIONSOptionWhat It Does-zCompress to (or uncompress from) gzip form. -jCompress to (or uncompress from) bzip2 form. -cCreate an archive. -xExtract from an archive. -tDisplay a list of the files in the archive. -vVerbose tell me what you re doing. -f fileWrite to (or read from) the archive file. Enter man tarat the command line for a completelisting of taroptions and flags. The GNU man pages are handy, but they canbe a bit overwhelming at times. Take a deepbreath and remember that you can close thepage at any time by entering q.
