You seem o be talking about https://pypi.python.org/pypi/oneliner
$ python3 -m oneliner --help
Usage: python -m oneliner [-hvnpdijl] [-m mod] [-e expr] [-s stmt] <path>
[<path> ...]
[snip]
-e expr python expression (see Execution Model)
-s stmt python statement (see Execution Model)
So you can either use -e with an expression
$ python3 -m oneliner -m re -ne 'line if re.search(r"\b\w{4}\b", line) else ""'
or -s with a statement
$ python3 -m oneliner -m re -ns 'if re.search(r"\b\w{4}\b", line): print(line,
end="")'
