40 .Nd remove directory entries
50 utility attempts to remove the non-directory type files specified on the
52 If the permissions of the file do not permit writing, and the standard
53 input device is a terminal, the user is prompted (on the standard error
54 output) for confirmation.
56 The options are as follows:
59 Attempt to remove directories as well as other types of files.
61 Attempt to remove the files without prompting for confirmation,
62 regardless of the file's permissions.
63 If the file does not exist, do not display a diagnostic message or modify
64 the exit status to reflect an error.
67 option overrides any previous
71 Request confirmation before attempting to remove each file, regardless of
72 the file's permissions, or whether or not the standard input device is a
76 option overrides any previous
80 Request confirmation once if more than three files are being removed or if a
81 directory is being recursively removed. This option only applies when the
83 utility is run in the foreground.
84 This is a far less intrusive option than
86 yet provides almost the same level of protection against mistakes.
88 Overwrite regular files before deleting them.
89 Files are overwritten three times, first with the byte pattern 0xff,
90 then 0x00, and then 0xff again, before they are deleted.
92 A file with a link count greater than one will neither be overwritten nor
93 removed, and a warning will be issued.
95 Attempt to remove the file hierarchy rooted in each file argument.
103 option is specified, the user is prompted for confirmation before
104 each directory's contents are processed (as well as before the attempt
105 is made to remove the directory).
106 If the user does not respond affirmatively, the file hierarchy rooted in
107 that directory is skipped.
112 Be verbose when deleting files, showing them as they are removed.
114 Attempt to undelete the named files.
115 Currently, this option can only be used to recover
116 files covered by whiteouts.
118 When removing a hierarchy, don't cross mount points.
123 utility removes symbolic links, not the files referenced by the links.
125 It is an error to attempt to remove the files
130 When the utility is called as
133 which must not be a directory,
135 No options may be supplied in this simple mode of operation,
138 operation on the passed argument.
142 utility exits 0 if all of the named files or file hierarchies were removed,
145 option was specified and all of the existing files or file hierarchies were
149 exits with a value >0.
159 signal, the current file or directory being removed
160 will be written to standard error.
166 to parse its arguments, which allows it to accept
169 option which will cause it to stop processing flag options at that
170 point. This will allow the removal of file names that begin
175 The same behavior can be obtained by using an absolute or relative
176 path reference. For example:
177 .Dl rm /home/user/-filename
182 utility differs from historical implementations in that the
184 option only masks attempts to remove non-existent files instead of
185 masking a large variety of errors.
188 option is non-standard and its use in scripts is not recommended.
192 implementations prompted on the standard output,
193 not the standard error output.
220 option assumes that the underlying file system is a fixed-block file
223 is a fixed-block file system, LFS is not.
224 In addition, only regular files are overwritten, other types of files
225 are not. Hardlinked regular files will not be overwritten or removed,
226 possibly leading to unintended behavior. It is arguable which is the MORE
