cat(1)                         DG/UX R4.11MU05                        cat(1)


NAME
       cat - concatenate and type files to standard output

SYNOPSIS
       cat [ -u ] [ -s ] [ -v [ -t ] [ -e ] ] [ -|file ] ...

   where:
       file   Name of file being typed

DESCRIPTION
       Cat reads each file (from left to right) and writes it on the
       standard output.  If no input file is given, or if the argument is -,
       cat reads from standard input.

       When the standard input is the keyboard and the standard output is
       the screen, cat prints back each line as you enter it (the new-line
       character and all other special characters cannot be escaped).  cat
       does not interpret characters.

       Using cat >file1 is a good way to create short files quickly.  Type
       ^d (Ctrl-D) to end input to the file.

       Options are:

       -u     Unbuffered output. The output is buffered unless you give this
              option.

       -s     Be silent about non-existent files; no error message is given.

       -v     Visible printing of nonprinting characters, except tabs
              (Ctrl-I), new lines (Ctrl-J), and form feeds (Ctrl-L).
              Control characters are printed ^X (representing Ctrl-X); the
              DEL character (octal 0177) is printed ^?.  Non-ASCII
              characters (with the high bit set) are printed as M-x, where x
              is the character specified by the seven low-order bits.

       -t     Print each tab as ^I, but only if the -v option is also
              present.  Otherwise, it is ignored.

       -e     Print a $ character at the end of each line (prior to the
              newline), but only if the -v option is also present.
              Otherwise, it is ignored.

   International Features
       cat can read and write files containing characters from supplementary
       code sets.

       NOTE:  When invoked with the -v option, cat considers all characters
              from supplementary code sets to be printable.

EXAMPLES
       cat file

       prints the file on the screen.

       cat file1 file2 > file3

       concatenates the first two files and places the result on the third.

       $ cat file1
            The
            quick
            brown
            fox
       $ cat file2
            jumped
            over
            the
            lazy
            dog.
       $ cat file1 file2 > file3
       $ cat file3
            The
            quick
            brown
            fox
            jumped
            over
            the
            lazy
            dog.

       The above example shows the concatenation of two different files into
       one file.

NOTE
       Sh(1) creates and/or opens the files for the output of the cat
       command before reading the files for its input.  Therefore, command
       formats such as
              cat file1 file2 > file1
       cause the original data in file1 to be lost; take care when using the
       shell special characters to specify files for cat to use.
