如何获取grep文件路径结果的插件名称？

Question

I have used grep -rsl "tinymce.plugins" . | sort grep -rsl "tinymce.plugins" . | sort grep -rsl "tinymce.plugins" . | sort to get a longer list of files including references to tinyMCE plugins. Here is a short excerpt of what the results list looks like:

./assets/javascripts/old/tiny_mce/plugins/preview/editor_plugin.js
./assets/javascripts/old/tiny_mce/plugins/preview/editor_plugin_src.js
./assets/javascripts/old/tiny_mce/plugins/print/editor_plugin.js
./assets/javascripts/old/tiny_mce/plugins/print/editor_plugin_src.js

I now want to find a way to make a list with all the plugin names and put it into a file.

Example:

results.txt:

preview
print

How can i achieve this? Thank you and sorry if my english is clunky.

Answer 1

You could try the below grep command,

$ command | grep -oP '[^\/]*(?=\/[^\/]*$)' | sort -u
preview
print

Answer 2

this awk one-liner gives you the result in one shot:

whatever|awk -F'plugins/' '{sub("/.*","",$2);$0=$2}!a[$0]++'

with your four lines, it outputs:

preview
print
