转换的bash`ls`输出JSON数组 [英] convert bash `ls` output to json array

问题描述

是否有可能使用bash脚本到 LS 的输出格式为JSON阵列？为了有效的JSON，显示目录和文件的所有名称必须用双引号，用逗号分隔，整个事情需要被放在方括号中。即转换：

Is it possible to use a bash script to format the output of the ls to a json array? To be valid json, all names of the dirs and files need to be wrapped in double quotes, seperated by a comma, and the entire thing needs to be wrapped in square brackets. I.e. convert:

jeroen@jeroen-ubuntu:~/Desktop$ ls
foo.txt bar baz

到

[ "foo.txt", "bar", "baz" ]

编辑：我强烈preFER的东西，所有我的Linux服务器的工作原理;因此，而不是靠蟒蛇，但有一个纯bash的解决方案。

edit: I strongly prefer something that works across all my Linux servers; hence rather not depend on python, but have a pure bash solution.

推荐答案

使用Perl作为EN codeR;它保证是无车，无处不在，并与管道，它仍然是合理的清洁：

Use perl as the encoder; it's guaranteed to be non-buggy, is everywhere, and with pipes, it's still reasonably clean:

ls | perl -e 'use JSON; @in=grep(s/\n$//, <>); print encode_json(\@in)."\n";'
