Editing Mkdir (section)

===Examples===
An example of <code>-p</code> in action is:

<syntaxhighlight lang="bash">
mkdir -p /tmp/a/b/c
</syntaxhighlight>

If <code>/tmp/a</code> exists but <code>/tmp/a/b</code> does not, <code>mkdir</code> will create <code>/tmp/a/b</code> before creating <code>/tmp/a/b/c</code>.

And an even more powerful command, creating a full tree at once (this however is a [[shell (computing)|Shell]] extension, nothing mkdir does itself):

<syntaxhighlight lang="bash">
mkdir -p tmpdir/{trunk/sources/{includes,docs},branches,tags}
</syntaxhighlight>

If one is using variables with mkdir in a bash script, [[POSIX]] `special' built-in command 'eval' would serve its purpose.

<syntaxhighlight lang="bash">
DOMAIN_NAME=includes,docs
eval "mkdir -p tmpdir/{trunk/sources/{${DOMAIN_NAME}},branches,tags}"
</syntaxhighlight>

This will create:
<syntaxhighlight lang="text">
          tmpdir
