BOMSTRIP(1) General Commands Manual BOMSTRIP(1)


bomstrip, bomstrip-files
strip the BOM sequence from UTF-8 files



bomstrip-files file ...


The bomstrip 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 bomstrip utility, trying to execute it as “bomstrip”; if the bomstrip 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 bomstrip:

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

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