有关shell脚本批量添加文件扩展名的方法，使用rename命令修改后缀名、用for、sed和mv修改后缀名、用find和xargs添加后缀名，方法很多，大家择优而用之吧。 shell脚本批量添加扩展名的方法 经测试可用的修改文件扩展名的二种方法：
方法1：
for file in `ls`; do mv $file $file.txt; done
方法2：
find . -type f |xargs -i mv {} {}.txt
以下添加文件扩展名的方法，未经测试，大家研究下。
1、用rename命令修改后缀名 >> linux下rename命令用法详解(重命名文件)
[root@demo test_rename]# ll
总计 20 -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
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
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 (责任编辑：IT) |
