Demand background

Because every weekend before the holiday to give the statistics of the number of code, if the manual statistics need to run the corresponding script under each developed project, too tedious. So write the following script for the first version of the code count

The code shown

The following is the amount of code in G:/project/tungee/. The part marked in red needs to be modified as your own project path and git mailbox

The first edition

Statistics by item

Use set -e to exit the script in case of an error instead of continuing. Use set-u to check if an unassigned variable is used; Try set-o Pipefail, which detects errors in pipes.

The fifth edition

There are two problems with today’s code:

As I cycles to zero,-$(($i-1))There is something wrong with this line of codeuntil_date 比 since_dateInstead, it was a day too early, resulting in script statistics errors
When the statistics of today’s code are transmitted, the current time of minute and second will be added by default to cause the statistics to fail, that is, the minute and second must be added, otherwise the statistics of today’s code cannot be collected
