ligang@centos6 test]$ ll total 4 -rw-r--r-- 1 ligang trainning 0 Mar 10 00:01 log2.txt drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:01 test1 -rw-r--r-- 1 ligang trainning 0 Mar 10 00:01 test.txt [ligang@centos6 test]$ mv log2.txt test.txt [ligang@centos6 test]$ ll total 4 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:01 test1 -rw-r--r-- 1 ligang trainning 0 Mar 10 00:01 test.txt
（2）文件内容覆盖centos
[ligang@centos6 test]$ ll total 12 -rw-r--r-- 1 ligang trainning 7 Mar 10 00:04 log1.txt drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:04 test1 -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 test.txt [ligang@centos6 test]$ cat log1.txt bcdefg [ligang@centos6 test]$ cat test.txt 123456 [ligang@centos6 test]$ mv test.txt log1.txt [ligang@centos6 test]$ cat log1.txt 123456
（3）文件夹下移动bash
[ligang@centos6 test]$ ^C [ligang@centos6 test]$ ll total 8 -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 log1.txt drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:04 test1 [ligang@centos6 test]$ touch log2.txt [ligang@centos6 test]$ mv lo* test1 [ligang@centos6 test]$ ll total 4 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:10 test1 [ligang@centos6 test]$ ll test1/ total 4 -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 log1.txt -rw-r--r-- 1 ligang trainning 0 Mar 10 00:10 log2.txt [ligang@centos6 test]$
（4）一大堆文件放入一个目录中spa
[ligang@centos6 test]$ ll total 4 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:10 test1 [ligang@centos6 test]$ mv test1/* ./ // 注把test下文件放在当前文件夹下不能用 mv test1 ./ [ligang@centos6 test]$ ll total 8 -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 log1.txt -rw-r--r-- 1 ligang trainning 0 Mar 10 00:10 log2.txt drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:18 test1 [ligang@centos6 test]$ ll test1/ total 0 [ligang@centos6 test]$ mv -t test1/ log1.txt log2.txt [ligang@centos6 test]$ ll total 4 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:19 test1 [ligang@centos6 test]$ ll test1/ total 4 -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 log1.txt -rw-r--r-- 1 ligang trainning 0 Mar 10 00:10 log2.txt [ligang@centos6 test]$
（5）-b选项文件覆盖前作简单备份code
ligang@centos6 test]$ ll total 0 -rw-r--r-- 1 ligang trainning 0 Mar 9 23:34 log1.txt -rw-r--r-- 1 ligang trainning 0 Mar 9 23:34 log2.txt [ligang@centos6 test]$ mv -b log1.txt log2.txt [ligang@centos6 test]$ ll total 0 -rw-r--r-- 1 ligang trainning 0 Mar 9 23:34 log2.txt -rw-r--r-- 1 ligang trainning 0 Mar 9 23:34 log2.txt~
[ligang@centos6 test]$ ll total 4 -rw-r--r-- 1 ligang trainning 0 Mar 10 00:35 haha.txt drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:19 test1 [ligang@centos6 test]$ cp haha.txt test1/ [ligang@centos6 test]$ ll test1/ total 4 -rw-r--r-- 1 ligang trainning 0 Mar 10 00:36 haha.txt -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 log1.txt -rw-r--r-- 1 ligang trainning 0 Mar 10 00:10 log2.txt [ligang@centos6 test]$ cp haha.txt test1/ [ligang@centos6 test]$ ll test1/ total 4 -rw-r--r-- 1 ligang trainning 0 Mar 10 00:36 haha.txt -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 log1.txt -rw-r--r-- 1 ligang trainning 0 Mar 10 00:10 log2.txt
（2）cp不能直接把文件夹复制给另一个文件夹，否者要加参数-rf。若是要把一个文件夹下内容复制给另一个文件夹则用dir/*orm
[ligang@centos6 test]$ cp test2/ test1 cp: omitting directory `test2/' [ligang@centos6 test]$ cp -rf test2/ test1 [ligang@centos6 test]$ ll total 12 -rw-r--r-- 1 ligang trainning 5 Mar 10 00:37 haha.txt drwxr-xr-x 3 ligang trainning 4096 Mar 10 00:42 test1 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:40 test2 [ligang@centos6 test]$ mkdir test3 [ligang@centos6 test]$ cp -af test3 test1 [ligang@centos6 test]$ ll test1 total 16 -rw-r--r-- 1 ligang trainning 5 Mar 10 00:37 haha.txt -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 log1.txt -rw-r--r-- 1 ligang trainning 0 Mar 10 00:10 log2.txt drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:42 test2 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:42 test3 [ligang@centos6 test]$ mkdir test4 [ligang@centos6 test]$ c test4 -bash: c: command not found [ligang@centos6 test]$ cd test4 [ligang@centos6 test4]$ touch test.txt [ligang@centos6 test4]$ cd .. [ligang@centos6 test]$ cp -rf test4/ test1 [ligang@centos6 test]$ ll test1 total 20 -rw-r--r-- 1 ligang trainning 5 Mar 10 00:37 haha.txt -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 log1.txt -rw-r--r-- 1 ligang trainning 0 Mar 10 00:10 log2.txt drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:42 test2 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:42 test3 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:45 test4 [ligang@centos6 test]$ cp test4/* test1 [ligang@centos6 test]$ ll test1 total 20 -rw-r--r-- 1 ligang trainning 5 Mar 10 00:37 haha.txt -rw-r--r-- 1 ligang trainning 7 Mar 10 00:07 log1.txt -rw-r--r-- 1 ligang trainning 0 Mar 10 00:10 log2.txt drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:42 test2 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:42 test3 drwxr-xr-x 2 ligang trainning 4096 Mar 10 00:45 test4 -rw-r--r-- 1 ligang trainning 0 Mar 10 00:45 test.txt
9，touchblog
功能：用来修改文件时间戳，或者新建一个不存在的文件。文档
-r 把指定文档或目录的日期时间，通通设成和参考文档或目录的日期时间相同。it
-t 使用指定的日期时间，而非如今的时间。格式： [[CC]YY]MMDDhhmm[.SS] io
