.TH mkdir 1 "27 Jul 2011" "SunOS 5.11" "User Commands"
.SH NAME
mkdir \- make directories
.SH SYNOPSIS
.LP
.nf
\fB/usr/bin/mkdir\fR [\fB-m\fR \fImode\fR] [\fB-p\fR] \fIdir\fR...
.fi

.SH DESCRIPTION
.sp
.LP
The \fBmkdir\fR command creates the named directories in mode \fB777\fR (possibly altered by the file mode creation mask \fBumask\fR(1)).
.sp
.LP
Standard entries in a directory (for instance, the files "\fB\&.\fR", for the directory itself, and "\fB\&.\|.\fR", for its parent) are made automatically. \fBmkdir\fR cannot create these entries by name. Creation of a directory requires write permission in the parent directory.
.sp
.LP
The owner-ID and group-ID of the new directories are set to the process's effective user-ID and group-ID, respectively. \fBmkdir\fR calls the \fBmkdir\fR(2) system call.
.SS "setgid and mkdir"
.sp
.LP
To change the \fBsetgid\fR bit on a newly created directory, you must use \fBchmod\fR \fBg+s\fR or \fBchmod\fR \fBg-s\fR after executing \fBmkdir\fR.
.sp
.LP
The \fBsetgid\fR bit setting is inherited from the parent directory.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.mk
.na
\fB\fB-m\fR \fImode\fR\fR
.ad
.RS 11n
.rt  
This option allows users to specify the mode to be used for new directories. Choices for modes can be found in \fBchmod\fR(1).
.RE

.sp
.ne 2
.mk
.na
\fB\fB-p\fR\fR
.ad
.RS 11n
.rt  
With this option, \fBmkdir\fR creates \fIdir\fR by creating all the non-existing parent directories first. The mode given to intermediate directories is the difference between \fB777\fR and the bits set in the file mode creation mask. The difference, however, must be at least \fB300\fR (write and execute permission for the user).
.RE

.SH OPERANDS
.sp
.LP
The following operand is supported:
.sp
.ne 2
.mk
.na
\fB\fIdir\fR\fR
.ad
.RS 7n
.rt  
A path name of a directory to be created.
.RE

.SH USAGE
.sp
.LP
See \fBlargefile\fR(5) for the description of the behavior of \fBmkdir\fR when encountering files greater than or equal to 2 Gbyte (2^31 bytes).
.SH EXAMPLES
.LP
\fBExample 1 \fRUsing \fBmkdir\fR
.sp
.LP
The following example:

.sp
.in +2
.nf
example% \fBmkdir -p ltr/jd/jan\fR
.fi
.in -2
.sp

.sp
.LP
creates the subdirectory structure \fBltr/jd/jan\fR.

.SH ENVIRONMENT VARIABLES
.sp
.LP
See \fBenviron\fR(5) for descriptions of the following environment variables that affect the execution of \fBmkdir\fR: \fBLANG\fR, \fBLC_ALL\fR, \fBLC_CTYPE\fR, \fBLC_MESSAGES\fR, and \fBNLSPATH\fR.
.SH EXIT STATUS
.sp
.LP
The following exit values are returned:
.sp
.ne 2
.mk
.na
\fB\fB0\fR\fR
.ad
.RS 6n
.rt  
All the specified directories were created successfully or the \fB-p\fR option was specified and all the specified directories now exist.
