Linux rename command example 2018-04-20 09:56
As we all known mv command can help me to rename one file. rename is another command to rename file and files. rename command is very useful for renaming multiple files. For example you have three files like following.
$ ll
total 0
-rw-r--r--. 1 root root 0 Apr 20 09:40 test1.txt
-rw-r--r--. 1 root root 0 Apr 20 09:40 test2.txt
-rw-r--r--. 1 root root 0 Apr 20 09:40 test3.txt
If you want to rename them to 'new_test1.txt', 'new_test2.txt' and 'new_test3.txt'. You can use mv command to rename them one by one. I recommend you to use rename command to rename them at once.
$ rename test new_test test?.txt
$ ll
total 0
-rw-r--r--. 1 root root 0 Apr 20 09:40 new_test1.txt
-rw-r--r--. 1 root root 0 Apr 20 09:40 new_test2.txt
-rw-r--r--. 1 root root 0 Apr 20 09:40 new_test3.txt
