Posted by The TechMentor in BASH, Scripts
on May 20th, 2014
If you spend much time at all coding or scripting you realize that you often do some of the same things over and over. That’s where functions and libraries come in. Having a library of commonly used functions handy helps speedup the coding process quite a bit. Usually I prefer to use the best tool for the job. That means using Perl, PHP, C, C++, BASH, or any other language suited for the task. However, lately I’ve been using BASH more than usual. Primarily because it’s pretty much guaranteed to be on just about ever, non Windows, system that I touch. Unfortunately, while I have an...

Bought a 6-pack of 4GB USB thumb drives for various backups. I installed them on liminf01, liminf03, and kfserver01. Used the following commands to format and mount them, since CentOS 5.10 did not automatically mount them. I originally went with the default FAT32 filesystems, but rsync filed to create symlinks, surprise! Step 1: Identify the proper device: $ ls -al /dev/sd* brw-r----- 1 root disk 8, 0 Apr 9 17:59 /dev/sda brw-r----- 1 root disk 8, 1 Apr 9 17:59 /dev/sda1 brw-r----- 1 root disk 8, 2 Apr 9 18:00 /dev/sda2 brw-r----- 1 root disk 8, 3 Apr 9 17:59 /dev/sda3 brw-r----- 1 root disk 8, 16 Apr...
