你如何正常化Bash的文件路径？ [英] How do you normalize a file path in Bash?

问题描述

我想改造 /富/酒吧/..为 /富

有哪些做到这一点bash命令？

Is there a bash command which does this?

编辑：在我的实际情况下，该目录是存在的。

in my practical case, the directory does exist.

推荐答案

如果你想从终日啃食的路径，目录名称和基名是你的朋友，而真实路径的文件名的一部分，是太方便。

if you're wanting to chomp part of a filename from the path, "dirname" and "basename" are your friends, and "realpath" is handy too.

dirname /foo/bar/baz 
# /foo/bar 
basename /foo/bar/baz
# baz
dirname $( dirname  /foo/bar/baz  )) 
# /foo 
realpath ../foo
# ../foo: No such file or directory
realpath /tmp/../tmp/../tmp
# /tmp

修改

真实路径似乎不是标准的问题。

Realpath appears not to be standard issue.

您可以用储备标准得到最接近的是

The closest you can get with the stock standard is

readlink -f  /path/here/.. 

真实路径似乎来自Debian的，并且不是的coreutils的一部分：
 <一href=\"http://packages.debian.org/unstable/utils/realpath\">http://packages.debian.org/unstable/utils/realpath
这原是DWWW包的一部分。

Realpath appears to come from debian, and is not part of coreutils: http://packages.debian.org/unstable/utils/realpath Which was originally part of the DWWW package.

（也可在Gentoo的应用程序管理员/真实路径）

( also available on gentoo as app-admin/realpath )

readlink -m /path/there/../../ 

运行方式相同

 realpath -s /path/here/../../

在于，实际存在的正常化它不需要的路径。

in that it doesn't need the path to actually exist to normalise it.
