rm 命令

常用示例

说明

rm removes files and directories. By default, it does not remove directories; use -r to remove directories recursively. Without -f, rm prompts for confirmation when removing write-protected files. With -i, it prompts for every file. The -I option provides a middle ground, prompting once for potentially dangerous operations. To remove a file starting with a dash, use -- to end option processing: rm -- -filename or use a path: rm ./-filename. The command unlinks files from the filesystem. Data may be recoverable until overwritten. For secure deletion, use shred.
