rm—removes files from directories
rm [–f] [–i] filename...
rm –r [–f] [–i] dirname...[filename...]
rm removes the entries for one or more files from a directory if the file has write permission. If filename is a symbolic link, the link will be removed, but the file or directory to which it refers will not be deleted. A user does not need write permission on a symbolic link to remove it, provided he or she has write permissions in the directory.
Example A.46.
1 rm file1 file2
2 rm -i *
3 rm -rf dir
EXPLANATION
Removes file1 and file2 from the directory. Removes all files in the present working directory, but asks first if it is okay. Recursively removes all files and directories below dir and ignores error messages.
