User Image Linux常用命令(2)--rm 2019-01-04

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.
