How Can I Efficiently Find and Remove UTF-8 Byte Order Marks (BOM) from Files?

Advanced UTF-8 BOM File Search and Modification

Searching for files with a UTF-8 byte order mark (BOM) can be tricky. While traditional shell scripts may suffice, there are more elegant and efficient methods available.

Find and Modify BOM-Prefixed Files

The following compact command locates and removes BOMs from files within the current directory:

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

Caution: This command will modify files that contain the specified BOM characters, even if they are not intended as BOMs. If you only want to identify files with BOMs, use this alternative:

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

Additional Tips

For text editors, consider using macros or plugins that automate BOM detection and removal. Additionally, check for features that support Unicode and UTF-8 encoding handling to ensure seamless editing of UTF-8 files.
