Shell脚本批量添加扩展名的两种方法分享
方法1:
代码如下:
for file in `ls`; do mv $file $file.txt; done
方法2:
代码如下:
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
代码如下:
[root@demo test_rename]# ll 总计 20 -rw-rCrC 1 root root 0 09-27 00:57 rename1.log -rw-rCrC 1 root root 0 09-27 00:57 rename2.log -rw-rCrC 1 root root 0 09-27 00:57 rename3.log -rw-rCrC 1 root root 0 09-27 00:57 rename4.log -rw-rCrC 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-rCrC 1 root root 0 09-27 00:57 rename1.txt -rw-rCrC 1 root root 0 09-27 00:57 rename2.txt -rw-rCrC 1 root root 0 09-27 00:57 rename3.txt -rw-rCrC 1 root root 0 09-27 00:57 rename4.txt -rw-rCrC 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
代码如下:
[root@demo test_rename]# ll 总计 20 -rw-rCrC 1 root root 0 09-27 01:51 rename1.log -rw-rCrC 1 root root 0 09-27 01:21 rename2.log -rw-rCrC 1 root root 0 09-27 01:21 rename3.log -rw-rCrC 1 root root 0 09-27 01:21 rename4.log -rw-rCrC 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-rCrC 1 root root 0 09-27 01:51 rename1.txt -rw-rCrC 1 root root 0 09-27 01:21 rename2.txt -rw-rCrC 1 root root 0 09-27 01:21 rename3.txt -rw-rCrC 1 root root 0 09-27 01:21 rename4.txt -rw-rCrC 1 root root 0 09-27 01:21 rename5.txt [root@demo test_rename]#
3.用find和xargs添加后缀名
代码如下:
[root@demo test_rename]# ll 总计 20 -rw-rCrC 1 root root 0 09-27 02:20 rename1 -rw-rCrC 1 root root 0 09-27 02:20 rename2 -rw-rCrC 1 root root 0 09-27 02:20 rename3 -rw-rCrC 1 root root 0 09-27 02:20 rename4 -rw-rCrC 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-rCrC 1 root root 0 09-27 02:20 rename1.txt -rw-rCrC 1 root root 0 09-27 02:20 rename2.txt -rw-rCrC 1 root root 0 09-27 02:20 rename3.txt -rw-rCrC 1 root root 0 09-27 02:20 rename4.txt -rw-rCrC 1 root root 0 09-27 02:20 rename5.txt [root@demo test_rename]#
