CAT(1)          DOMAIN/IX Reference Manual (SYS5)          CAT(1)



NAME
     cat - concatenate and print files

USAGE
     cat [ -u ] [ -s ] [ -v [ -t ] [ -e ] ] file ...

DESCRIPTION
     Cat reads each named file in sequence, then writes it on the
     standard output. If file is omitted and - is used instead,
     cat reads from standard input.

OPTIONS
     -u   Produce unbuffered output.

     -s   Ignore files that do not exist.

     -v   Make nonprinting characters visible (except for tabs,
          newlines, and form feeds).  Print control characters as
          ^X (CONTROL-X), the DEL character (octal 0177) as a
          caret with a question mark (^?), and non-ASCII charac-
          ters (with the high bit set) as M-x (where x is the
          character specified by the seven low-order bits).

     -t   With the -v option, print tabs as ^I.

     -e   With the -v option, print a dollar sign ($) at the end
          of each line (prior to the newline).

     Note that cat ignores the -t and -e options if the -v option
     is not specified.

EXAMPLES
     To write file1 on standard output, type the following:

          cat file1

     To write standard input to file1, use this command:

          cat >file1

     To write file1 and file2 to file3, type this:

          cat file1 file2 >file3

CAUTIONS
     Command formats such as cat file1 file2 >file1 destroy the
     original data in file1.  Be careful when using Shell special
     characters.

RELATED INFORMATION
     cp (1), pr (1).
