windows下編寫的腳本，上傳到linux上執行，有時會出現莫名其妙的結果，也是折騰了半天才找出原因，windows和linux有些編碼不同，經dos2unix處理后，結果一切正常man dos2unix結果如下，英文不難理解，一看就基本懂，所以也懶得翻譯了NAME dos2unix - DOS/MAC to UNIX text file format converterSYNOPSYS dos2unix [options] [-c convmode] [-o file ...] [-n infile outfile ...] Options: [-hkqV] [--help] [--keepdate] [--quiet] [--version]DESCRipTION This manual page documents dos2unix, the PRogram that converts plain text files in DOS/MAC format to UNIX format.OPTIONS The following options are available: -h --help Print online help. -k --keepdate Keep the date stamp of output file same as input file. -q --quiet Quiet mode.
