SYNOPSIS¶

DESCRIPTION¶
Identifies the language files are written in using Perl module Lingua::Identify.
OPTIONS¶
Show all results (not just the most probable language).
Show confidence level for most probable language (it will be the first value
right after the most probable language).
Debug (development only).
-E ENCODING¶
Select an input encoding. Defaults to UTF-8.
# use ISO-8859-1 (latin1)
langident -E ISO-8859-1 file
-e METHODS¶
Select the method(s) to use. There are three ways of doing this:
# simply using a method
langident -e ngrams3 file
# using several methods (separate them with a comma)
langident -e prefixes3,suffixes3
# using several methods and assign different weights to each of them
langident -e smallwords=2,prefixes=1,ngrams3=1.3
The available methods are the following:
smallwords,
prefixes1,
prefixes2,
prefixes3,
prefixes4,
suffixes1,
suffixes2,
suffixes3,
suffixes4,
ngrams1,
ngrams2,
ngrams3 and
ngrams4.
Display help message and exit.
List all available languages and exit.
-m NUMBER¶
Set maximum number of results (languages) to display (shows the N most probable
languages, by descending order of probability).

Also show percentages.
-s SIZE¶
Maximum size to examine.
Show version and exit.
EXAMPLES¶
Use methods ngrams2 and ngrams1, assigning the double of importance to ngrams2
(-e switch); output will include the three most probable languages (-m switch)
with its percentages (-p switch) and also the confidence level (-c switch) of
the first result.
