Remove multiple BOMs from a file

See also: Using awk to remove the Byte-order mark

To remove multiple BOMs from anywhere within a text file you can try something similar. Just leave out the ^ anchor:

perl -e 's/\xef\xbb\xbf//;' -pi~ file.js

(This edits the file in-place. But creates a backup file.js~.)

I normally do it using vim:

vim -c "set nobomb" -c wq! myfile
