auto_ef(1) User Commands auto_ef(1) NAME
auto_ef - auto encoding finder SYNOPSIS
/usr/bin/auto_ef [-e encoding_list] [-a] [-l level] [file ...] /usr/bin/auto_ef -h DESCRIPTION
The auto_ef utility identifies the encoding of a given file. The utility judges the encoding by using the iconv code conversion, determin- ing whether a certain code conversion was successful with the file, and also by performing frequency analyses on the character sequences that appear in the file. The auto_ef 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). ASCII JIS ISO-2022-JP eucJP Japanese EUC PCK Japanese PC Kanji, CP932, Shift JIS UTF-8 Korean EUC ko_KR.euc ko_KR.cp949 Unified Hangul ISO-2022-KR ISO-2022 Korean zh_CN.iso2022-CN ISO-2022 CN/CN-EXT zh_CN.euc Simplified Chinese EUC, GB2312 GB18030 Simplified Chinese GB18030/GBK zh_TW-big5 BIG5 zh_TW-euc Traditional Chinese EUC zh_TW.hkscs Hong Kong BIG5 iso-8859-1 West European, and similar iso-8859-2 East European, and similar iso-8859-5 Cyrillic, and similar iso-8859-6 Arabic iso-8859-7 Greek iso-8859-8 Hebrew CP1250 windows-1250, corresponding to ISO-8859-2 CP1251 windows-1251, corresponding to ISO-8859-5 CP1252 windows-1252, corresponding to ISO-8859-1 CP1253 windows-1253, corresponding to ISO-8859-7 CP1255 windows-1255, corresponding to ISO-8859-8 koi8-r corresponding to iso-8859-5 By default, auto_ef 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, auto_ef 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% auto_ef -a test_file eucJP 0.89 zh_CN.euc 0.04 ko_KR.euc 0.01 Without this option, only one encoding with the highest score is shown. -e encoding_list Examines data only with specified encodings. For example, when encoding_list is specified as "ko_KR.euc:ko_KR.cp949", auto_ef examines text only with CP949 and ko_KR.euc. Without this option, auto_ef examines text with all encodings. Multiple encodings can be specified 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 levels. The default is level 0. OPERANDS
The following operands are supported: file File name to examine. EXAMPLES
Example 1: Examining encoding of a file example% auto_ef file_name Example 2: Examining encoding of a file at level 2. example% auto_ef -l 2 file_name Example 3: Examining encoding of a file with only eucJP or ko_KR.euc example% auto_ef -e "eucJP:ko_KR.euc" file_name EXIT STATUS
The following exit values are returned: 0 Successful completion 1 An error occurred. ATTRIBUTES
