User Commands autoef(1)
NAME
autoef - auto encoding finder
SYNOPSIS
/usr/bin/autoef [-e encodinglist] [-a] [-l level]
[file ...]
/usr/bin/autoef -h
DESCRIPTION
The autoef utility identifies the encoding of a given file.
The utility judges the encoding by using the iconv code
conversion, determining whether a certain code conversion
was successful with the file, and also by performing fre-
quency analyses on the character sequences that appear in
the file.
The autoef utility might produce unexpected output if the
string is binary, a character table, a localized digit list,
or a chronogram, or if the string or file is very small in
size (for example, less than one 100 bytes).

User Commands autoef(1)
By default, autoef returns a single, most likely encoding
for text in a specified file. To get all possible encodings
for the file, use the -a option.
Also by default, autoef uses the fastest process to examine
the file. For more accurate results, use the -l option.
To examine data with a limited set of encodings, use the -e
option.
OPTIONS
The following options are supported:
-a Shows all possible encodings in order of
possibility, with scores in the range
between 0.0 and 1.0. A higher score
means a higher possibility. For example,
example% autoef -a testfile
eucJP 0.89
zhCN.euc 0.04
koKR.euc 0.01
Without this option, only one encoding
with the highest score is shown.
-e encodinglist Examines data only with specified encod-
ings. For example, when encodinglist is
specified as "koKR.euc:koKR.cp949",
autoef examines text only with CP949
and koKR.euc. Without this option,
autoef examines text with all encod-
ings. Multiple encodings can be speci-
fied by separating the encodings using a
colon (:).
-h Shows the usage message.
-l level Specifies the level of judgment. The
value of level can be 0, 1, 2, or 3.
Level 3 produces the best result but can
be slow. Level 0 is fastest but results
can be less accurate than in higher lev-
els. The default is level 0.
