[root@localhost ~]# mysqlbinlog /data/3306/logs/ray-bin.000004 -v -v -S /data/3306/soket/mysql.sock --base64-output=decode-rows | sed -n '/### DELETE FROM `testdb1`.`student`/,/COMMIT/P' | sed -n 's\### \\p' | sed "s/\/\*.*\*\///g" | sed 's/`//g' > /tmp/1.txt

[root@localhost ~]# sed 's/DELETE FROM/insert into/g' /tmp/1.txt | sed 's/WHERE/select/g' | sed 's/@4.*/\0;/g' | sed 's/@[1-3].*/\0,/g' | sed 's/[^@]\(.*\)=//g' > execSQL.sql

要點：

sed 's/@4.*/\0;/g' 把@4後面匹配所有字元所有長度，替換，在匹配的後面新增。\0代表整行;

sed 's/@[1-3].*/\0,/g' 把@後面從1到3匹配，在匹配後面所有字元所有長度，在匹配項後面新增逗號。\0代表整行。

sed 's/[^@]\(.*\)=//g' 把已@開頭的到=以內的內容替換
