shell--record an advanced level of personal script

This script is used in the common shell syntax of the work, the trivial grammar together can help to deal with work, liberation of manpower.

The main common shell knowledge points:

1. Determine if the parameters exist and determine the number of parameters

2. declaring functions

3. Judging string equality

4. The judgment string contains

5. Determine array contents and arrays, and loop arrays

6. If multi-conditional syntax

7. Sed
   

The script is recorded in order to record some basic grammar, the future can be forgotten to scroll. The basic grammar is used properly, and the work of operation and maintenance is better assisted. The script only applies to some special requirements.
