       cat - concatenate, copy, and print files

       file ...

       reads  each  file  in  sequence	and  writes it on the standard output.

       prints file on the default standard output device;

       concatenates file1 and file2, and places the result in file3.

       If is appears as a file argument,  uses	standard  input.   To  combine
       standard	 input	and  other  files, use a combination of and file argu‐

       recognizes the following options:

	      Omit line numbers from blank lines when
		   option is specified.	 If  this  option  is  specified,  the
		   option is automatically selected.

	      Print a
		   character  at the end of each line (prior to the new-line).
		   If this option is specified, the  option  is	 automatically

	      Display output lines preceded by line numbers, numbered
		   sequentially from 1.

	      Replace multiple consecutive empty lines with one empty
		   line,  so  that  there  is  never  more than one empty line
		   between lines containing characters.

	      Silent option.
		   suppresses error messages about non-existent files, identi‐
		   cal	input  and  output, and write errors.  Normally, input
		   and output files cannot have	 identical  names  unless  the
		   file is a special file.

	      Print each tab character as
		   and form feed character as If this option is specified, the
		   option is automatically selected.

	      Do not buffer output (handle character-by-character).
		   Normally, output is buffered.

	      Cause non-printing characters
		   (with the exception of tabs, new-lines and  form-feeds)  to
		   be  printed	visibly.  Control characters are printed using
		   the form (Ctrl-X), and the DEL character  (octal  0177)  is
		   printed  as (see ascii(5)).	Single-byte control characters
		   whose most significant bit is set, are  printed  using  the
		   form	 where	x  is the character specified by the seven low
		   order bits.	All other non-printing characters are  printed
		   as  where  x	 is  the  character specified by the seven low
		   order bits.	This option is influenced by  the  environment
		   variable and its corresponding code set.

   Environment Variables
       provides	 a  default  value for the internationalization variables that
       are unset or null. If is unset or null, the default value of  "C"  (see
       lang(5)) is used. If any of the internationalization variables contains
       an invalid setting, will behave as if  all  internationalization	 vari‐
       ables are set to "C".  See environ(5).

       If  set	to  a  non-empty string value, overrides the values of all the
       other internationalization variables.

       determines the interpretation of text as single and/or multi-byte char‐
       acters,	the classification of characters as printable, and the charac‐
       ters matched by character class expressions in regular expressions.

       determines the locale that should be used to affect the format and con‐
       tents  of diagnostic messages written to standard error and informative
       messages written to standard output.

       determines the location of message catalogues for the processing of

   International Code Set Support
       Single- and multi-byte character code sets are supported.

       Exit values are:

	   0	  Successful completion.
	  >0	  Error condition occurred.

       To create a zero-length file, use any of the following:

       The following prints for all the occurrences of tab character in file1

       To suppress error messages about files that do not exist, use:

       If file2 does not exist, the above command concatenates file1 and file3
       without reporting the error on file2.  The result is the same if option
       is not used, except that displays the error message.

       To view non-printable characters in file2, use:

       Command formats such as

       overwrites the data in file1  before  the  concatenation	 begins,  thus
       destroying  the	file.	Therefore, be careful when using shell special

       cp(1), more(1), pg(1), pr(1), rmnl(1), ssp(1).
