Clear PHP BOM Header

Locate the file that contains the BOM header, as follows:

Grep-r-i-l $ ' ^\xef\xbb\xbf '.

This command will find all the files containing the BOM header in the current directory and subdirectories, and output the file name on the screen.

However, the deletion of the BOM header, the Web-found commands are mostly not available, the more common commands are:

Grep-r-i-l $ ' ^\xef\xbb\xbf '/path | Xargs sed-i ' s/^\xef\xbb\xbf//;q '

But this command removes all rows except the first line, so it makes no sense.

It is possible to test the following commands:

Find. -type f-exec sed-i ' s/\xef\xbb\xbf//' {} \;

This command removes the BOM header from the current directory and all subdirectories.
