find 命令用法总结

实例 1


首先应该想到的方法便是使用 find 命令,如下:

[root@xxx_admin res]# find ./ -type f | wc -l

然后还看到这样不那么直接, 使用 grep 命令来查找并统计,如下:

[root@xxx_admin res]# ls -lR | grep "^-" | wc -l

上面统计的数目为什么相差 1,现在还没想明白。

实例 2

man find 中的例子

find . -type f -exec file '{}' \;

Runs ‘file’ on every file in or below the current directory. 
Notice that the braces are enclosed in single quote marks to 
protect them from interpretation as shell script punctuation.  
The semicolon is similarly protected by the use of a backslash, 
though single quotes could have been used in that case also.

实例 3

称动当前目录的 test.log 文件 到 /tmp 目录下

[root@VM_15_187_centos ~]# find ./ -type f -iname "test.log" -exec ls -l  {} \;
-rw-r--r-- 1 root root 27 Mar 21 15:23 ./test.log
[root@VM_15_187_centos ~]# find ./ -type f -iname "test.log" -exec mv {} /tmp/ \; # 注意 -exec 写法,经常以为是两个"-"
[root@VM_15_187_centos ~]# ll /root/test.log /tmp/test.log 
ls: cannot access /root/test.log: No such file or directory
-rw-r--r-- 1 root root 27 Mar 21 15:23 /tmp/test.log


Linux 统计某文件夹下文件、文件夹的个数
