rfmkdir
RFMKDIR(1) Rfio User Commands RFMKDIR(1)
NAME
rfmkdir - make remote directories
SYNOPSIS
rfmkdir [ -m mode ] [ -p ] directory...
DESCRIPTION
rfmkdir provides an interface to the shift remote file I/O daemon (rfiod) for creating remote directories in mode 777 (possibly altered by
umask(1)). The directory argument is either a remote directory name of the form:
hostname:path
or a local directory name (not containing the :/ character combination). Creation of a directory requires write permission in the parent
directory.
OPTIONS
The following options apply to rfmkdir:
-m mode
This option allows users to specify the mode to be used for the new directories. Choices for modes can be found in chmod(1).
-p With this option, rfmkdir creates dirname by creating all the non-existing parent directories first.
SEE ALSO
mkdir(1), umask(1), mkdir(2), rfiod(1)
