linux下使用shell批量修改文件名几种方法总结

1、通过sed替换
[root@node01 wolf]# find / -type f -name wolf.log
/wolf.log
/tmp/wolf.log
/root/wolf/wolf.log
[root@node01 wolf]# sed -i 's#wolf#yujing#g' find / -type f -name wolf.log
[root@node01 wolf]# find / -type f -name "wolf.log" | xargs cat
yujing
yujing
yujing
[root@node01 wolf]#

2、通过变量子串替换
vi laolang.log
wolf_20170806_1_wolf.jpg
wolf_20170806_2_wolf.jpg
wolf_20170806_3_wolf.jpg
wolf_20170806_4_wolf.jpg
wolf_20170806_5_wolf.jpg
wolf_20170806_6_wolf.jpg
wolf_20170806_7_wolf.jpg
wolf_20170806_8_wolf.jpg
wolf_20170806_9_wolf.jpg
wolf_20170806_10_wolf.jpg
[root@node01 data]# touch cat laolang.log |tr "\\n" " "
[root@node01 data]# ll

3、修改扩展名
把上面的jpg更换为log
[root@node01 data]# f=wolf_20170806_10_.jpg
[root@node01 data]# echo ${f/%jpg/log}
wolf_20170806_10_.log
[root@node01 data]# mv $f ${f/%jpg/log}
[root@node01 data]# ls
apache-maven-3.3.9 day1 laolang.log wolf_20170806_2_.jpg wolf_20170806_5_.jpg wolf_20170806_8_.jpg
apache-maven-3.3.9-bin.tar.gz day2 wolf_20170806_10_.log wolf_20170806_3_.jpg wolf_20170806_6_.jpg wolf_20170806_9_.jpg
