|
||||
Usage: ./rm_ [OPTION]... [-T] SOURCE DEST
|
||||
or: ./rm_ [OPTION]... SOURCE... DIRECTORY
|
||||
or: ./rm_ [OPTION]... -t DIRECTORY SOURCE...
|
||||
Rename SOURCE to DEST, or move SOURCE(s) to DIRECTORY.
|
||||
|
||||
Mandatory arguments to long options are mandatory for short options too.
|
||||
--backup[=CONTROL] make a backup of each existing destination file
|
||||
-b like --backup but does not accept an argument
|
||||
-f, --force do not prompt before overwriting
|
||||
-i, --interactive prompt before overwrite
|
||||
-n, --no-clobber do not overwrite an existing file
|
||||
If you specify more than one of -i, -f, -n, only the final one takes effect.
|
||||
--strip-trailing-slashes remove any trailing slashes from each SOURCE
|
||||
argument
|
||||
-S, --suffix=SUFFIX override the usual backup suffix
|
||||
-t, --target-directory=DIRECTORY move all SOURCE arguments into DIRECTORY
|
||||
-T, --no-target-directory treat DEST as a normal file
|
||||
-u, --update move only when the SOURCE file is newer
|
||||
than the destination file or when the
|
||||
destination file is missing
|
||||
-v, --verbose explain what is being done
|
||||
-Z, --context set SELinux security context of destination
|
||||
file to default type
|
||||
--help display this help and exit
|
||||
--version output version information and exit
|
||||
|
||||
Instead of rm command to prevent mistaken deletion of files

代替rm命令,以防止错误删除文件
|
||||
作者: aixiao@aixiao.me
|
||||
|
||||
The backup suffix is '~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
|
||||
The version control method may be selected via the --backup option or through
|
||||
the VERSION_CONTROL environment variable. Here are the values:
|
||||
|
||||
none, off never make backups (even if --backup is given)
|
||||
numbered, t make numbered backups
|
||||
existing, nil numbered if numbered backups exist, simple otherwise
|
||||
simple, never always make simple backups
