Shell腳本批量添加擴展名的兩種方法分享
方法1:
for file in `ls`; do mv $file $file.txt; done
方法2:
find . -type f |xargs -i mv {} {}.txt
還有一些試驗不成功的,先記錄在此。
1.用rename命令修改后綴名,這個是最簡單最省事的辦法
[root@demo test_rename]# ll
總計 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改為*.txt
[root@demo test_rename]# ll
總計 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修改后綴名
[root@demo test_rename]# ll
總計 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
總計 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添加后綴名
[root@demo test_rename]# ll
總計 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
總計 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]#
