Line Ending Settings

The default line ending in VS Code is CRLF (\r\n).

If CRLF is mixed into Linux scripts, it causes errors, so set the line ending to LF (\n).

By the way, for files that have already been created, you can open the Command Palette and use "Change End of Line Sequence" to change the line ending.

Displaying Line Endings

Make it visible whether a file uses CRLF or LF.

By installing the code-eol extension, you can distinguish between CRLF and LF at a glance.
