NAME

ud - Converts text files between UNIX, DOS, and Macintosh formats

SYNOPSIS

/usr/bin/ud [{-d | -u | -m } -z] [file]

OPTIONS

file The name of the input file to be converted. If no options are specified, ud attempts to determine whether this file is a DOS or a UNIX format file, and converts accordingly. If no input file is specified, ud takes its input from standard input. -d Converts the input file to DOS format, replacing newline characters with a combination of carriage return and line feeds. -u Converts the input file to UNIX format. -m Converts the input file to Macintosh format. -z Causes ud to ignore or not emit the Ctrl/Z character found at the end of most DOS files.

DESCRIPTION

The ud program converts a DOS file to UNIX system format or a UNIX system file to DOS format, and sends the result to standard output. Without any options, ud determines the format of the input file, and converts it from DOS to UNIX or from UNIX to DOS accordingly. Text files created in DOS usually use a combination carriage return and line feed to mark the end of each line of text, while UNIX text lines are terminated with a single newline character. In addition, DOS files often end with a Ctrl/Z character, while UNIX files do not. The ud command can also be used to convert text files to and from the Macintosh file format. Like many similar UNIX commands, the output can be redirected to a second file with the redirection operator ( > ) or to a second program with a pipe ( | ).

EXAMPLES

1. To convert a UNIX file called text.unx to DOS format, and place the output in a file called text.dos, enter: ud -d text.unx >text.dos 2. To convert a UNIX system file calledunixtext to OS/2 format, then sort the file and place the output in a file called text.srt, enter: ud -d unixtext | sort>text.srt

SEE ALSO

Commands: unix2dos(1as), dos2unix(1as)
