• 修改文件编码方式从utf-8到ansi

iconv -f utf8 -t gbk -o ansi.txt utf8.txt

-f: from

-t: to

• 查看文件编码方式

file <filename>

# cp @ cp in ~/cp_lab/src/lexer [10:38:09] 
$ file lexical_analyzer_utf8.l 
lexical_analyzer_utf8.l: C source, UTF-8 Unicode text, with CRLF line terminators #utf-8

# cp @ cp in ~/cp_lab/src/lexer [10:38:17] 
$ file lexical_analyzer.l     
lexical_analyzer.l: C source, ISO-8859 text, with CRLF line terminators #ansi
