Keyword based inline Search and Replace with sed

sed is a nifty utility that allows you to search and replace text in a file using a short 1-liner.

The following command does the following:
1. Searches for the keyword in every line of the input_file

3. It replaces every instance of search_string with replace_string

sed '/keyword/s/search_string/replace_string/g' input_file

Neat!
