How to Elegantly Find UTF-8 Files with BOM?

Find UTF-8 Files with BOM Elegantly

Identifying files with a UTF-8 byte order mark (BOM) can be crucial for debugging purposes. While traditional methods like shell scripts can fulfill this task, it is worth exploring alternative approaches for their brevity and elegance.

Harnessing Find and Sed

One concise solution leverages the find command to recursively search for files and the sed command to process their contents. The following command not only finds files with BOMs but also removes them:

<code class="bash">find . -type f -exec sed '1s/^\xEF\xBB\xBF//' -i {} \;</code>

Note that this operation modifies binary files containing the BOM sequence. For a non-invasive approach that simply identifies BOM files, use:

<code class="bash">grep -rl $'\xEF\xBB\xBF' .</code>

Additional Tips

Beyond the command line, text editors like Sublime Text offer plugins that can search for and handle BOMs. Additionally, macros can be customized to automate BOM-related tasks in specific editors.
