本文介绍了一个Bash脚本，用于解析Git日志并统计提交最多的作者。脚本支持显示所有作者、特定数量的顶级作者或默认显示前五名作者。通过命令行参数，用户可以灵活地选择查看的信息。

赋值操作，不要加空格，被坑了

#!/bin/bash

function show(){

  #var = "$1"
  var="$1"
  echo -e "var: $var"
  echo -e "var: $1"
  if [ ! $var ];then
    if [ $var = "-h" ];then
      echo -e "-h to show help\n-a to show all\n-number(like -3 ) to show number of Author\n if end with null,will show top 5 Author default"
    elif [ $var = "-a" ];then
      echo -e "Author :"
      git log |grep Author |sort -n |uniq -c |sort -nr
    else
      echo -e "top $var Author :"
      git log |grep Author |sort -n |uniq -c |sort -nr|head $var
    fi 
  else
    echo -e "top 5 Author :"
    git log |grep Author |sort -n |uniq -c |sort -nr|head -5
  fi

}

show $1

final version:

#!/bin/bash
#use this program to show git Author 
function show()
{
  #set var = "$1"
  var="$1"
  echo -e "var: $var"
  if [ $var ];then
    if [ $var = "-h" ];then
      echo -e "-h to show help\n-a to show all\n-number(like -3 ) to show number of Author\n if end with null,to show top 5 Author by default"
    elif [ $var = "-a" ];then
      echo -e "all Author :"
      git log |grep Author |sort -n |uniq -c |sort -nr
    else
      echo -e "top $var Author :"
      git log |grep Author |sort -n |uniq -c |sort -nr|head $var
    fi 
  else
    echo -e "top 5 Author :"
    git log |grep Author |sort -n |uniq -c |sort -nr|head -5
  fi
}

show $1
