移动文件

mv file1 file2
将文件file1改名为file2,

mv file dir
将文件file移动到目录dir中,

mv file1 file2 file3 dir
mv -t dir file1 file2 file3
将文件file1,file2和file3移动到目录dir中,

mv -i file1 file2
将文件file1改名为file2,如果file2已经存在,则询问是否覆盖,i=interactive, prompt before overwrite,
一般情况下,我们使用的mv是一个别名:alias mv='mv -i'

mv -f file1 file2
将文件file1改名为file2,即使file2存在,也是直接覆盖掉,f=force, do not prompt before overwriting,这是个危险的选项,最好不用加上它,

mv dir1 dir2
如果目录dir2不存在,将目录dir1改名为dir2;否则,将dir1移动到dir2中
