From OS X 10.5 (Leopard) Apple introduced Time Machine: a great combination of rsync/rsnapshot and a beautiful user interface. Time Machine works in two modes: 1. local volume on local area or 2. Time Capsule over network. Now I don’t wanna buy another box with apple logo over it for much $$$ when I have a lot of file servers on my network. Now I explain a few hoops to get this system to work: ...
There is no direct RPM option available via rpm command to extract an RPM file. But there is a small utility available called rpm2cpio. It Extract cpio archive from RPM Package Manager (RPM) package. Example extract RPM file using rpm2cpio and cpio command: # rpm2cpio somepackage.x86_64.rpm | cpio -idmv Output of rpm2cpio piped to cpio command with following options: i: Restore archive d: Create leading directories where needed m: Retain previous file modification times when creating files v: Verbose
