[sujin@localhost blog]$ ls -l
total 0
-rw-rw-r--. 1 sujin sujin 0 Oct 19 13:12 centos6file1
-rw-rw-r--. 1 sujin sujin 0 Oct 19 13:12 centos6file2
-rw-rw-r--. 1 sujin sujin 0 Oct 19 13:12 centos6file3
-rw-rw-r--. 1 sujin sujin 0 Oct 19 13:12 centos6file4
-rw-rw-r--. 1 sujin sujin 0 Oct 19 13:12 centos6file5
-rw-rw-r--. 1 sujin sujin 0 Oct 19 13:14 centos6file6
-rw-rw-r--. 1 sujin sujin 0 Oct 19 13:14 centos6file7
-rw-rw-r--. 1 sujin sujin 0 Oct 19 13:14 centos6file8

From the above  list of files i want change all the filename  starting with centos6 to centos7. I mean file centos6file2 changed to centos7file2. 

It is bit time consuming using mv command to change it one by one. Persong who using mv command for do this not a good linux user. 

By using a linux command called rename we can achieve this.

         rename centos6 centos7 centos6*

After applying above command file name list would be like below.

[sujin@localhost blog]$ rename centos6 centos7 centos6*

[sujin@localhost blog]$ 

[sujin@localhost blog]$ ls -l
