1. Use the rename command

SYNOPSIS
rename from to file...
from indicates the characters that need to be replaced or processed, such as the file extension, the file name.

to indicates the result after processing from.

file represents the target file.


[root@liujianfan tmp]# ls
hello_10_2016-03-17.log  hello_4_2016-03-17.log  hello_8_2016-03-17.log
hello_1_2016-03-17.log   hello_5_2016-03-17.log  hello_9_2016-03-17.log
hello_2_2016-03-17.log   hello_6_2016-03-17.log
hello_3_2016-03-17.log   hello_7_2016-03-17.log
Use rename to change .log to .jpg

[root@liujianfan tmp]# rename ".log" ".jpg" *
[root@liujianfan tmp]# ls
hello_10_2016-03-17.jpg  hello_4_2016-03-17.jpg  hello_8_2016-03-17.jpg
hello_1_2016-03-17.jpg   hello_5_2016-03-17.jpg  hello_9_2016-03-17.jpg
hello_2_2016-03-17.jpg   hello_6_2016-03-17.jpg
hello_3_2016-03-17.jpg   hello_7_2016-03-17.jpg
2. Use sed:

[root@liujianfan tmp]# ls|sed -nr "s#(^.*[0-9].) (.*)#mv & \1log#gp"
mv hello_10_2016-03-17.jpg hello_10_2016-03-17.log
mv hello_1_2016-03-17.jpg hello_1_2016-03-17.log
mv hello_2_2016-03-17.jpg hello_2_2016-03-17.log
mv hello_3_2016-03-17.jpg hello_3_2016-03-17.log
mv hello_4_2016-03-17.jpg hello_4_2016-03-17.log
mv hello_5_2016-03-17.jpg hello_5_2016-03-17.log
mv hello_6_2016-03-17.jpg hello_6_2016-03-17.log
mv hello_7_2016-03-17.jpg hello_7_2016-03-17.log
mv hello_8_2016-03-17.jpg hello_8_2016-03-17.log
mv hello_9_2016-03-17.jpg hello_9_2016-03-17.log
Finally, pipe the bash process:

[root@liujianfan tmp]# ls|sed -nr "s#(^.*[0-9].) (.*)#mv & \1log#gp"|bash
[root@liujianfan tmp]# ls
hello_10_2016-03-17.log  hello_4_2016-03-17.log  hello_8_2016-03-17.log
hello_1_2016-03-17.log   hello_5_2016-03-17.log  hello_9_2016-03-17.log
hello_2_2016-03-17.log   hello_6_2016-03-17.log
hello_3_2016-03-17.log   hello_7_2016-03-17.log
3. Use for and then replace the string

[root@liujianfan tmp]# vim rename.sh
#!/bin/bash
#This script is use to rename files
for name in `ls *.log`;
do
echo "mv $name ${name/.log/.txt}"
done
Finally via bash:

[root@liujianfan tmp]# ./rename.sh |bash
[root@liujianfan tmp]# ls
hello_10_2016-03-17.txt  hello_4_2016-03-17.txt  hello_8_2016-03-17.txt
hello_1_2016-03-17.txt   hello_5_2016-03-17.txt  hello_9_2016-03-17.txt
hello_2_2016-03-17.txt   hello_6_2016-03-17.txt  rename.sh
hello_3_2016-03-17.txt   hello_7_2016-03-17.txt
