不知道的时候就可以
$ cp --help 或者$ man cp 第一种方法的部分输出是: Usage: cp [OPTION]... [-T] SOURCE DEST or: cp [OPTION]... SOURCE... DIRECTORY or: cp [OPTION]... -t DIRECTORY SOURCE... Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY. Mandatory arguments to long options are mandatory for short options too. -a, --archive same as -dR --preserve=all --attributes-only don't copy the file data, just the attributes --backup[=CONTROL] make a backup of each existing destination file ... -d same as --no-dereference --preserve=links ... -P, --no-dereference never follow symbolic links in SOURCE -p same as --preserve=mode,ownership,timestamps --preserve[=ATTR_LIST] preserve the specified attributes (default: mode,ownership,timestamps), if possible additional attributes: context, links, xattr, all --no-preserve=ATTR_LIST don't preserve the specified attributes --parents use full source file name under DIRECTORY -R, -r, --recursive copy directories recursively --reflink[=WHEN] control clone/CoW copies. See below --remove-destination remove each existing destination file before attempting to open it (contrast with --force) --sparse=WHEN control creation of sparse files. See below --strip-trailing-slashes remove any trailing slashes from each SOURCE argument ... 里面提了 -a 相当于 -dR --preserve=all -d 是不跟随符号链接;R 是递归拷贝。在拷贝目录的时候需要,会把子目录一并拷贝。否则默认是不拷贝目录的。-p 描述是否保留源文件属性的。说明有点长,自己看吧。 一般归档用 tar 更多些,楼主如果有兴趣也可以去看看 tar 的手册页。 [ 本帖最后由 pangding 于 2012-9-14 20:52 编辑 ] |
刚开始看linux,有一点不懂
cp复制命令中参数-a :相当于-pdr的意思
想问一下pdr什么意思?
