1. 先複製純文字匯出 txt 為 csv
   

   [root@moodle ~]# cd /var/www/html/moodle23/grade
   [root@moodle grade]# cp -a export/txt export/csv
   [root@moodle grade]# diff -qr export/csv export/txt/
   

2. 更改檔名
   

   [root@moodle grade]# cd csv
   [root@moodle csv]# mv export_txt.php export_csv.php
   [root@moodle csv]# mv gradeexport_txt.php gradeexport_csv.php
   [root@moodle grade]# cd -
