Linux常用命令（2）--rm

一常用

1.rm -rf filename 删除目录（文件）及子目录不做提示

2. rm -ri temp.tar 删除时提示

3. rm -rvI * 删除当前目录下的所有问题，只提示一次，并且列出当前删除项

二命令使用

Usage: rm [OPTION]... [FILE]...
Remove (unlink) the FILE(s).

-f, --force ignore nonexistent files and arguments, never prompt 忽略不存在的文件和参数，不提示
-i prompt before every removal 在删除前提示
-I prompt once before removing more than three files, or 只提示一次
when removing recursively; less intrusive than -i,
while still giving protection against most mistakes
--interactive[=WHEN] prompt according to WHEN: never, once (-I), or
always (-i); without WHEN, prompt always
--one-file-system when removing a hierarchy recursively, skip any
directory that is on a file system different from
that of the corresponding command line argument
--no-preserve-root do not treat '/' specially
--preserve-root do not remove '/' (default)
-r, -R, --recursive remove directories and their contents recursively 以递归方式删除目录及其内容
-d, --dir remove empty directories 删除空的目录
-v, --verbose explain what is being done 详细列出正在处理的文件
--help display this help and exit
--version output version information and exit

By default, rm does not remove directories. Use the --recursive (-r or -R)
option to remove each listed directory, too, along with all of its contents.

To remove a file whose name starts with a '-', for example '-foo',
use one of these commands:
rm -- -foo

rm ./-foo

Note that if you use rm to remove a file, it might be possible to recover
some of its contents, given sufficient expertise and/or time. For greater
assurance that the contents are truly unrecoverable, consider using shred.
