批量创建文件及批量修改文件名实战
批量创建文件:
#!/bin/bash [ ! -d /data ] && mkdir /data for i in {1..10} do mkdir -p /data/xcn_$i.html done 执行结果: [root@XCN for]# sh test5.sh [root@XCN for]# ll /data/ total 40 drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_1.html drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_10.html drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_2.html drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_3.html drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_4.html drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_5.html drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_6.html drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_7.html drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_8.html drwxr-xr-x 2 root root 4096 Jul 2 15:27 xcn_9.html
批量更改文件名:用for循环实现以上文件中的xcn全部改成Linux,并且扩展名为大写
注意:for环境体不能出现xcn字符串
#!/bin/bash cd /data for f in `ls *.html` do mv $f `echo $f|sed 's#xcn#linux#g'|sed 's#html#HTML#g'` done
