<h2>Tilde expansions</h2>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
An unquoted tilde character (<strong>~</strong>) at the
|
||
|
|
beginning of a word is expanded according to the following rules:
|
||
|
|
<ul>
|
||
|
|
<li><strong>~</strong> expands to the value of the <strong>HOME</strong>
|
||
|
|
variable (the current user's home directory).</li>
|
||
|
|
<li><strong>~user</strong> expands to the home directory of the specified user. All
|
||
|
|
the characters up to a slash (<strong>/</strong>) or the end of the
|
||
|
|
word are treated as a user name.</li>
|
||
|
|
<li><strong>~+</strong> expands to the value of the <strong>PWD</strong>
|
||
|
|
(working directory) variable.</li>
|
||
|
|
<li><strong>~-</strong> expands to the value of the <strong>OLDPWD</strong>
|
||
|
|
(previous working directory) variable if it is set.</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
