19.1.2 企业Shell面试题2：批量改名特殊案例

将以上面试题19.1.1中结果文件名中的oldboy字符串全部改成oldgirl(最好用for循环实现),并且将扩展名html全部改成大写。

rename oldboy.html   oldgirl.HTLM   *_oldboy.html

[root@jenkins scripts]# ls
2.sh                    daargnrenb_oldboy.html  expect_test.sh          mqqbylcynk_oldboy.html  test1_2.sh              tt.sh
3.sh                    eqtaoyqljo_oldboy.html  hjnovpxobc_oldboy.html  qxtacetuas_oldboy.html  test1.sh                vfrmwfbyqq_oldboy.html
cdfkdshngs_oldboy.html  expect2_test.sh         kpgmywjidh_oldboy.html  test                    tgpmpmufdv_oldboy.html  yneepywxaw_oldboy.html
[root@jenkins scripts]# rename oldboy.html   oldgirl.HTLM   *_oldboy.html

[root@jenkins scripts]# ls
2.sh                     daargnrenb_oldgirl.HTLM  expect_test.sh           mqqbylcynk_oldgirl.HTLM  test1_2.sh               tt.sh
3.sh                     eqtaoyqljo_oldgirl.HTLM  hjnovpxobc_oldgirl.HTLM  qxtacetuas_oldgirl.HTLM  test1.sh                 vfrmwfbyqq_oldgirl.HTLM
