There are also some unsuccessful experiments, which are recorded here first.

-rw-r-r- 1 root root 0 09-27 00:57 rename3.log

-rw-r-r- 1 root root 0 09-27 00:57 rename4.log

-rw-r-r- 1 root root 0 09-27 00:57 rename5.log

[root@demo test_rename] # rename log txt * .log # change * .log to * .txt

[root@demo test_rename] # ll

-rw-r-r- 1 root root 0 09-27 01:21 rename3.log

-rw-r-r- 1 root root 0 09-27 01:21 rename4.log

-rw-r-r- 1 root root 0 09-27 01:21 rename5.log

[root@demo test_rename] # for i in $(ls.)

> do

> mv $I $(echo $I | sed's /\ .log /\ .txt /')

> done

[root@demo test_rename] # ll

-rw-r-r- 1 root root 0 09-27 02:20 rename2

-rw-r-r- 1 root root 0 09-27 02:20 rename3

-rw-r-r- 1 root root 0 09-27 02:20 rename4

-rw-r-r- 1 root root 0 09-27 02:20 rename5

[root@demo test_rename] # find. -type f | xargs-I mv {}. Txt

[root@demo test_rename] # ll

Total 20

-rw-r-r- 1 root root 0 09-27 02:20 rename1.txt
