如何使用 bash 从除第一个文件夹之外的所有路径获取

bash 如何从除第一个文件夹之外的所有路径获取？

例如

从'a/b/d/e'得到'b/d/e'

现在我用 pythonpy 做到这一点

$ pip install pythonpy
$ echo 'a/b/d/e' | py -x '"/".join(x.split("/")[1:])'
b/d/e
$

#Cyrius 解决方案运行良好::

$ x='a/b/d/e'
$ echo "${x#*/}"
b/d/e
$

但在阅读Parameter Expansion 后，唯一相关的例子${parameter#...}是：

${parameter#word}
${parameter##word}

  The word is expanded to produce a pattern just as in filename expansion (see 
  Filename Expansion). If the pattern matches the beginning of the expanded value
  of parameter, then the result of the expansion is the expanded value of
  parameter with the shortest matching pattern (the ‘#’ case) or the longest
  matching pattern (the ‘##’ case) deleted. If parameter is ‘@’ or ‘*’, the
  pattern removal operation is applied to each positional parameter in turn, and
  the expansion is the resultant list. If parameter is an array variable
  subscripted with ‘@’ or ‘*’, the pattern removal operation is applied to each
  member of the array in turn, and the expansion is the resultant list.

这对我理解什么是由 "${x#*/}"
