本文主要是介绍Shell脚本批量添加扩展名的两种方法分享，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
方法1：
for file in `ls`; do mv $file $file.txt; done
方法2：
find . -type f |xargs -i mv {} {}.txt
还有一些试验不成功的，先记录在此。
1.用rename命令修改后缀名，这个是最简单最省事的办法
[root@demo test_rename]# ll

-rw-r–r– 1 root root 0 09-27 00:57 rename1.log
-rw-r–r– 1 root root 0 09-27 00:57 rename2.log
-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 #把*.log改为*.txt
[root@demo test_rename]# ll
总计 20
-rw-r–r– 1 root root 0 09-27 00:57 rename1.txt
-rw-r–r– 1 root root 0 09-27 00:57 rename2.txt
-rw-r–r– 1 root root 0 09-27 00:57 rename3.txt
-rw-r–r– 1 root root 0 09-27 00:57 rename4.txt
-rw-r–r– 1 root root 0 09-27 00:57 rename5.txt
[root@demo test_rename]#
2.用for、sed和mv修改后缀名
[root@demo test_rename]# ll
总计 20
-rw-r–r– 1 root root 0 09-27 01:51 rename1.log
-rw-r–r– 1 root root 0 09-27 01:21 rename2.log
-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
总计 20
-rw-r–r– 1 root root 0 09-27 01:51 rename1.txt
-rw-r–r– 1 root root 0 09-27 01:21 rename2.txt
-rw-r–r– 1 root root 0 09-27 01:21 rename3.txt
-rw-r–r– 1 root root 0 09-27 01:21 rename4.txt
-rw-r–r– 1 root root 0 09-27 01:21 rename5.txt
[root@demo test_rename]#
3.用find和xargs添加后缀名
[root@demo test_rename]# ll
总计 20
-rw-r–r– 1 root root 0 09-27 02:20 rename1
-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
总计 20
-rw-r–r– 1 root root 0 09-27 02:20 rename1.txt
-rw-r–r– 1 root root 0 09-27 02:20 rename2.txt
-rw-r–r– 1 root root 0 09-27 02:20 rename3.txt
-rw-r–r– 1 root root 0 09-27 02:20 rename4.txt
-rw-r–r– 1 root root 0 09-27 02:20 rename5.txt
[root@demo test_rename]#
