條列記一些學習到的東西：
- The test command is used to verify that the file was created.
- The -f tag is needed to check that the specified file exists and is a regular file.
- The grep command is used for searching lines that match a regular expression. It does a global search with the regular expression and prints all matching lines.
- yaml裡的job預設是水平跑，所以要用stages來定義順序
- >> 是appending， > 會整個取代。 ex: echo “miou” >> cat.txt
