test -e fff.txt || touch fff.txt
It will create an empty file fff.txt if it doesn't exist.
Other thing when you use cat > <file> It also create the file if is not present and if it present it over writes the contents.

bomstrip
BOMSTRIP(1) BSD General Commands Manual BOMSTRIP(1)
NAME
bomstrip, bomstrip-files -- strip the BOM sequence from UTF-8 files
SYNOPSIS
bomstrip
bomstrip-files file ...
DESCRIPTION
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 com-
plex command is desired, it may be supplied in the BOMSTRIP environment variable.
EXAMPLES
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
SEE ALSO
The bomstrip home page: http://www.xs4all.nl/~mechiel/projects/bomstrip/
HISTORY
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 lan-
guages.
