  NAME
       cat -- concatenate and display text files

  SYNOPSIS
       cat [-su] [-v[et]] [file...]

  DESCRIPTION
       cat displays and concatenates files.  It copies each file argu-
       ment to the standard output.  If you specify no files or give -
       as a file name, cat reads the standard input.

  Options
       cat accepts the following options:

       -e   displays a $ character at the end of each line.  This option
            only works if you also specify -v.

       -s   does not produce an error message if cat cannot find or read
            a specified file.

       -t   displays tabs as ^I. This option only works if you also
            specify -v.

       -u   does not buffer output.

       -v   displays all characters including those that are unprint-
            able. If the most significant bit in a character is set and
            the character is non-printable, cat displays the character
            without that bit, but precedes it with the characters M-.
            cat displays other unprintable characters as ^ followed by
            the character representing the control character (for
            example, ^A for CTRL-A).

  DIAGNOSTICS
       Possible exit status values are:

       0  Successful completion.

       1  An error occurred.

  Messages

       Message:  filename: system error
       Cause:    See syserror(3).
       Action:   See syserror(3).

       Message:  input file "filename" is identical with output
       Cause:    You specified filename as both an input and output

                 linked to filename.
       Action:   Use a file other than filename as the output file.
