title: Illegal option -p /bin/sh: 1: Usage:: not found
body: <p>I am using Linux and
  I get source code of AT91BootStrap from the git repository</p>
  
  <pre><code>git clone git://github.com/linux4sam/at91bootstrap.git
  </code></pre>
  
  <p>After cloning the repository and under AT91Bootstrap root directory, I find a board/sama5d27_som1_ek folder which contains several default configuration files.</p>
  
  <p>I can configure AT91Bootstrap to load from SD Card by doing:</p>
  
  <pre><code>$ make mrproper
  $ make sama5d27_som1_eksd_uboot_defconfig
  </code></pre>
  
  <p>But when I enter <code>make sama5d27_som1_eksd_uboot_defconfig</code>   command in Linux terminal it shows me an error saying : </p>
  
  <blockquote>
    <p>Illegal option -p /bin/sh: 1: Usage:: not found</p>
  </blockquote>
  
  <p>How can I solve this ?</p>
  
  <p>This is the tutorial I am following :

  <p>This is the output of <code>mkdir --help</code> :</p>
  
  <pre><code>Usage: mkdir [OPTION]... DIRECTORY...
  Create the DIRECTORY(ies), if they do not already exist.
  
  Mandatory arguments to long options are mandatory for short options too.
    -m, --mode=MODE   set file mode (as in chmod), not a=rwx - umask
    -p, --parents     no error if existing, make parent directories as needed
    -v, --verbose     print a message for each created directory
    -Z                   set SELinux security context of each created directory
                           to the default type
        --context[=CTX]  like -Z, or if CTX is specified then set the SELinux
                           or SMACK security context to CTX
        --help     display this help and exit
        --version  output version information and exit
