如何从文件路径获取文件目录路径? [英] How to get a file directory path from file path?

问题描述

在Bash中，如果 VAR ="/home/me/mydir/file.c" ，如何获得"/home/me/mydir" ?

In Bash, if VAR="/home/me/mydir/file.c", how do I get "/home/me/mydir"?

推荐答案

dirname 和 basename 是您正在寻找的提取路径分量的工具:

dirname and basename are the tools you're looking for for extracting path components:

$ export VAR='/home/pax/file.c'
$ echo "$(dirname "${VAR}")" ; echo "$(basename "${VAR}")"
/home/pax
file.c

它们不是内部Bash命令，但它们是POSIX标准的一部分-请参见 basename .因此，它们可能在大多数能够运行 bash 的平台上可用，或者可以在大多数平台上获得.

They're not internal Bash commands but they're part of the POSIX standard - see dirname and basename. Hence, they're probably available on, or can be obtained for, most platforms that are capable of running bash.
