Unix Stuff

Backups

Useful schemes and scripts for doing those all-important system backups. If you don't yet have an effective backup package, one or both of these may be useful. Method 1 needs a CD-R (or a tape) somewhere on the system or network. Method 2 (the older and by far the most comprehensive script) assumes access to a SCSI tape drive such as an Exabyte or a DAT.

1. CD-R Backup - Basic CD-R and DVD based backup and recovery system for unix/linux. Script, file-splitter program, etc.

2. TPIO - A more comprehensive script for tape-based backup and recovery - allows full or delta backups (and much more). Maintains a set of indexes on both tape and disc for quick and easy file and tape identification. Written around 1990 but still in intermittent use here and there ...

Misc

3. VIB - VI with backups. Creates backups of each file you edit before calling vi. Great for recovering from those ba-a-a-ad late night creative editing sessions (when you suddenly wish you'd stopped hacking 3 hours ago}:-)

4. hd - hex dump. Small program for dumping file contents in hexadecimal + ASCII. (After you upload it, rename it to plain hd - the .bin on the end is just to stop netscape from trying to display it as text).

5. What? An environment that's system independent? Yep - for those of you who are becoming just a little bored with each flavour of Unix (SGI, HP, SunOS, Solaris, Linux) each being so unique at the CLI level, use this setup to get a command-line environment that works consistently on all of them!

6. roll_web_logs - a wrapper for webalizer that allows it to be run in non-incremental mode without taking all day to do the resolving. (Assumes that you already know how to set up webalizer in its basic form.) The script also references a couple of control files in /etc/init.d. They're pretty standard, but if you want copies, just click here for my www and/or realmedia start/stop scripts.

7. Linux and Cygwin annoyances - This is a rambling "notes" file that I add to from time to time to help myself remember some of the more obscure tricks in getting Linux to run smoothly. This started off when I discovered after installing my first Linux that the Backspace and Delete keys on Linux are reversed by default. (Under X, it gets even worse - Backspace sends Delete (= 0x7F) and Delete sends an Esc)

8. Windoze annoyances - As above, but for Windoze. Started this file on Dec 14, 2005 after suffering from two perplexing faults in the same week.
