I just wrote this bash shell script to delete all pending/spam/trash comments from WordPress (Single or Multisite) using WP-CLI: Put the script inside your WordPress root and run: $ ./clean_comments.sh These are available statuses of a comment: approve : approved comments hold : pending comments spam : spams trash : comments in the trash bin This is pretty neat huh?!

To remove both leading and trailing spaces of a string in bash shell, you can do like following: mytext=' This is a test ' trimed_text="$(echo -e "${mytext}" | sed -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//')"

One of the big problem when you migrate your WordPress blog to another server with a new domain name is the media gallery. What happened to me was even though I had already moved all the photos (media) to the new location but nothing showed up in the Media dashboard and all the gallery shortcode in posts were broken. I figured out earlier today that I need to update the media links or attachments attribute when I importing the old data (exported WXR file). Here is the step-by-step detail: (I'm doing this for my multisite WordPress) 1. In the old WordPress: Export old blog data (Tools > Export > select All Content > press Download Export File). You will have a xml file. 2. Copy over all the photos from the old WordPress to the new one. For example: Old: /var/www/oldblog/wp-content/blogs.dir/777/ New: /var/www/newblog/wp-content/uploads/sites/777/ 3. Open the export file using a text editor. Search and replace the old media path with the new one. For example: Ol

This is a pretty neat python snippet I wrote to read an Excel (xlsx) file and convert its data into a list of dictionaries: Note: you need to install the openpyxl module before you can use the snippet $ sudo pip install openpyxl So, you can use the snippet as following: >> from excel_utils import excel_to_dict >> data = excel_to_dict('/path/to/excel/file.xlsx', ['col1', 'col2', 'col3']) >> data[0] {'col1': u'Genius',  'col2': u'Super',  'col3': u'Awesome'} Cool huh?
