Shallow incremental code on-line shell script-Rookie version

1 Description

this Shell script is the first generation of my written version of the Delta Code on-line script, now the code-on-line script has been updated several versions, focus on the technical focus is to visualize the code version of any rollback of the online system (Python language), These scripts ^_^ are gradually shared later . Although it seems that the script is very miserable, but at that time changed the company's online approach, from the handover of the manual on-line, change to script Automation online, is also a starting point and a turning point.

2 Module Analysis

This online script function is relatively simple, first see the online overall process:

The following is a detailed on-line flowchart:

Please open this document using "notepad++" or another editor, "Alt+0" to make it easy to review after folding the function.

This shell script, is the initial practiced hand, it is difficult to see clearly is sure, the overall write sucks, but in small places some small tricks, really can let the small partners for reference.

Hope that through this series of articles to record their growth footsteps, no one can suddenly become Daniel, after the polishing of time, let us step-by-step change it!!!

Where the script is deficient:

1. Code readability is poor

2. Whether rsync execution is complete or not checked for correctness

3. Rsync does not perform timeout processing
