TUC(1) BSD General Commands Manual TUC(1)NAMEtuc — Text to Unix Conversion (v1.10)
SYNOPSIStuc [-d|D] [-i inputfile] [-o outputfile]
tuc [-d|D] [inputfile [outputfile]]
DESCRIPTION
The tuc utility converts text files from DOS, or any operating system to
UNIX style text files. As of version 1.10, it optionally converts files
to DOS style text files.
Tuc does more than simply strip (or insert) carriage returns. It uses a
state machine to check for the following line endings:
cr/lf
cr/lf/lf... (for multiple lines)
cr
lf/cr
lf
Because of that, tuc can convert files created under any operating system
to UNIX text files.
The tuc utility exits 0 on success, 1 when the command line is invalid,
or 2 when it cannot open a file.
USAGE
Converting to UNIX
To convert a file to UNIX text file simply enter:
tuc inputfile outputfile
Inputfile is a text file created in any operating system. It can use any
combination of carriage returns and line feeds as line terminators.
If no outputfile is specified, the output is sent to stdout. Similarly,
if no inputfile is listed, tuc reads its input from stdin.
If you wish to read input from stdin but send output to a file, use the
-o flag followed by outputfile. For example,
tuc-o outputfile
You may also use the -i flag to specify inputfile explicitly. If you use
both -i and -o switches, you may list the files in any order.
Converting to DOS
Starting with version 1.10, tuc can also convert UNIX files, or files
created under any operating system, to DOS style text files. This
requires the -d or -D switch, with a subtle difference between the two.
Which switch you should use depends on the operating system.
-D will always produce DOS style output.
-d produces DOS style output if outputfile is specified. However, if out‐
put is sent to stdout, tuc will produce UNIX style output. This is
because tuc can be compiled as both a UNIX program and a DOS program. DOS
opens the console in the cooked mode. That means, DOS appends carriage
returns after all line feeds sent to the console.
You only need -D under UNIX. Under DOS, choose between -d and -D, depend‐
ing on where you want to send the output.
Examples
Save the output of a UNIX program to a DOS text file:
unixprogram | tuc-D -o dostextfile
Save the output of a DOS program to a UNIX text file:
dosprogram | tuc-o unixtexfile
Filter the output of a DOS program as input to a UNIX program:
dosprogram | tuc | unixprogram
Filter the output of a UNIX program as input to a DOS program:
unixprogram | tuc-D | dosprogram
