寫一個項目裏詞條對比的shell

需求：找出當前開發分支裏未上傳到詞條平臺的詞條

#! /bin/bash
#-----------------------------------------------------------------------#
# 手動版說明:
# 1、將此shell放在項目根目錄裏跟.git目錄平級;
# 2、如果查找的分支顯示沒有修改，有可能是已經合到master了,所以沒有差異;
# 3、如果想自己查找某個目錄裏的所有詞條，直接在相應目錄執行 grep "\bt('[^']\+'"  -ro .|  awk -F "'" '{print $2}' | sort -u
#-----------------------------------------------------------------------#

# 對應平臺的標識 aaa 3 bbb 7 ccc 60
# aaa | bbb | ccc
projectName=$(git remote -v |head -n 1 | awk '{print $2}' | sed 's/.*\///'| sed 's/\.git//')
