3.5 Requirements

KBACKUP requires some other software to be installed on your system. However, most of them should be available on any properly installed UNIX system. If you are using a Slackware-based LINUX , all you need is to install afio(1) on your machine.

The programs required by KBACKUP are:

• dialog : the dialog program is being used for doing all the user interaction. If dialog(1) is not available, KBACKUP will fall back to . Without dialog(1) , it is still fully functional (just a bit ugly)!
• gtar : the GNU tape archiver. A normal tar(1) will not do! Under LINUX , tar(1) is GNU's tar , so do not worry.
• afio : the archive program. It is KBACKUP 's preferred archive handler, somehow more powerful than tar , but less well tested.
• grep , fgrep , sed : some text processing programs that should be installed on every proper UNIX system.

In fact, you do not need both, tar(1) and afio(1) . KBACKUP can use either of them to handle its archives. Afio is strongly recommended. For handling encrypted archives , you should get afio(1) version 2.4.2 or newer.

In the file paths , you can set environment variables pointing to the various programs. Just in case the standard settings should not work for you.

KBACKUP should run with any Bourne Shell (sh(1) ) compatible shell. However, I have mainly tested it using the Bourne-Again Shell (bash(1) ), therefore I cannot guarantee that it will work with others, but I do not see any problems. Especially, it appears to be working well with the rather small ash(1) shell, which is of interest for putting it onto boot disks.
