Bash Regex multiple optional captures

4 Views

I’m trying to get information out of wordpress plugins, the plugin name and the version.

I’m finding that the line I’m looking for could be Plugin Name:, Plugin Name:, Plugin Name: , or * Plugin Name: or variations of space. Since the line I”m looking for is in the comments part, it may also include the *

I’ve gotten as far as getting the whitespace optional, I think, but i can’t figure out capturing the * with space around it. 

grep "^s*Plugin Name:" $files

which is working for most of the plugins but not all, since some have other characters to watch out for.

I’ve tried 

(s*)?|( * )?  
[ *]|[ * ]? 
( *| * )?

but I’m having a hard time wrapping my head around stringing it all together.

Edit:
Using 

grep -E '^s**?s*Plugin Name:' $files

will find everything, but two of the plugins in this case now, that have * Plugin Name: will print out an entirely different directory in addition to the correct information.

$plugPath is the wordpress plugins folder – /wp-content/plugins 

folders=`find $plugPath -maxdepth 1 -type d`
for plugin_folder in $folders
do
    echo $plugin_folder
    files=`find $plugin_folder -maxdepth 1 -name "*.php"`

    n=`grep -hE '^s**?s*Plugin Name:' $files`
    v=`grep -hE '^s**?s*Version:' $files`
    echo " -- "$n
    echo " -- "$v
done

Result I’m expecting: 

/home/test/accounts/account-one/public_html/wp-content/plugins/flexible-recent-posts
 -- Plugin Name: Flexible Recent Posts
 -- Version: 1.0.4

Example that is working: 

Plugin Name: Flexible Recent Posts
Plugin URI: http://steelrat.info/
Description: Displays recent posts using flexible template system.
Version: 1.0.4
Author: SteelRat

Where it’s screwing up: 

/home/test/accounts/account-one/public_html/wp-content/plugins/portfolio-post-type
 --  2015.11.13-AccountInfo.log.csv accounts bin Desktop Documents Downloads latest.tar.gz Music Pictures Public Templates test-info.log.csv Videos wordpress Plugin Name: Portfolio Post Type
 --  2015.11.13-AccountInfo.log.csv accounts bin Desktop Documents Downloads latest.tar.gz Music Pictures Public Templates test-info.log.csv Videos wordpress Version: 0.9.1

The file it finds these in is like: 

 * Plugin Name: Portfolio Post Type
 * Plugin URI:  http://wptheming.com/portfolio-post-type/
 * Description: Enables a portfolio post type and taxonomies.
 * Version:     0.9.1

  1. A simple:

    grep "Plugin Name:"

    is not enough?

    UPDATE

    Then try this version:

    grep -E '^s*[*]?s*Plugin Name:'

    Or an equivalent:

    grep -E '^s**?s*Plugin Name:'

    UPDATE 2

    Probably the loop in the updated question suffer the non-adequately-quoted-filename syndrome. I suggest a find one-liner to obtain almost the same functionality:

    find "${WORDPRESS_PLUGIN_DIR}" -mindepth 2 -maxdepth 2 -iname "*.php" -exec grep -E '^s**?s*(Plugin Name|Version):' {} ;

  2. This catches everything, including spaces prior, plus a single space past Plugin Name:

    grep -G "^.*Plugin Name:s" $files
