bomstrip-files(1) strip the BOM sequence from UTF-8 files

Other Alias



bomstrip-files file ...


The utility reads UTF-8 data from its standard input and copies it to its standard output, stripping the BOM (byte-order mark) from the beginning of the text if it is present. There are no command-line options and no parameters.

The bomstrip-files utility removes the UTF-8 BOM from the specified files, saving each file's original contents with a .bom extension. It uses the utility, trying to execute it as `` '' if the utility is installed under another name, or if a more complex command is desired, it may be supplied in the BOMSTRIP environment variable.


Strip the BOM, if present, from a text file:

bomstrip < bom.txt > nobom.txt

Strip the BOM, if present, from all text files, backing them up with a .bom extension:

bomstrip-files *.txt

Use the OCAML implementation of :

env BOMSTRIP='ocaml bomstrip.ocaml' bomstrip-files *.txt


The utility (in many languages) was written by An Mechiel Lukkien , with implementations in various languages sent to him by others, including An Andreas Gohr , An Andrew Gerrand , An Berteun Damman , An Matthijs Bomhoff , An Peter Pentchev , and An Ruben Smelik . The bomstrip-files utility and this manual page were written by An Peter Pentchev in the hope that they reflect the behavior of all the implementations in all languages.
