Shell Tools script collection

An assortment of generally useful shell i.e. (BASH, SH, CSH & other language) scripts for use on the command line.

The scripts comprising shellTools are created with an emphasis on:

- code quality (reliable operation in diverse environments)

- readability (both in source code and tool usage documentation)

- comfort in usage (gentle learning curves with sensible default behaviors)

##shellTools includes:

• activityLog
  Designed to be run unattended from a cron job, activityLog is a basic
  "system vitals" logging script which creates system activity 'snapshot' tar.gz files.
  The system load averages (1, 5, 15) & a timestamp are what comprise a snapshot filename.
  Each such snapshot is a text file containing the following information.
  1.) Top
  2.) Netstat (Complete connection list, Processeslist per port, & Network throughput/interface)
  3.) MySQL processlist (sampled for 15 seconds at 1/4 second resolution)

(Special thanks to @thefunkjunky for a very clean port of activityLog to python)

• diskSpeedTest
  A simple disk transfer (write) speed test using dd and some
  nested loops to run through a set of many common block sizes
  and counts. diskSpeedTest requires no parameters (not yet anyway)
  and will generate a simple log file describing the performance
  metrics achieved by your storage device at various block sizes & counts.

• tableTaker A robust table-by-table data export script for MySQL.
  featuring timestamped database output directories (by default)
  with support for user specified output directory names.
  tableTaker also allows an easy way to compress the exported table output SQL.
