For debugging purposes, I need to recursively search a directory for all files which start with a UTF-8 byte order mark (BOM). My current solution is a simple shell script:
find -type f | while read file do if [ "`head -c 3 -- "$file"`" == $'\xef\xbb\xbf' ] then echo "found BOM in: $file" fi done
Or, if you prefer short, unreadable one-liners:
find -type f|while read file;do [ "`head -c3 -- "$file"`" == $'\xef\xbb\xbf' ] && echo "found BOM in: $file";done
It doesn't work with filenames that contain a line break,
but such files are not to be expected anyway.
Is there any shorter or more elegant solution?
Are there any interesting text editors or macros for text editors?
