NAME

       cat, read, nobs - catenate files

SYNOPSIS

       cat [ file ...  ]
       read [ -m ] [ -n nline ] [ file ...  ]
       nobs [ file ...	]

DESCRIPTION

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

	      cat file

       prints a file and

	      cat file1 file2 >file3

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

       If no file is given, cat reads from the standard input.	Output is buffered in blocks matching the input.

       Read copies to standard output exactly one line from the named file, default standard input.  It is useful in interactive rc(1) scripts.

       The -m flag causes it to continue reading and writing multiple lines until end of file; -n causes it to read no more than nline lines.

       Read  always  executes  a single write for each line of input, which can be helpful when preparing input to programs that expect line-at-a-
       time data.  It never reads any more data from the input than it prints to the output.

       Nobs copies the named files to standard output except that it removes all backspace characters and the characters that precede them.  It is
       useful to use as $PAGER with the Unix version of man(1) when run inside a win (see acme(1)) window.

DIAGNOSTICS

       Read exits with status eof on end of file or, in the -n case, if it doesn't read nlines lines.

BUGS

       Beware of and which destroy input files before reading them.

Name
       cat - concatenate and print data

Syntax
       cat [ -b ] [ -e ] [ -n ] [ -s ] [ -t ] [ -u ] [ -v ] file...

Description
       The  command reads each file in sequence and displays it on the standard output.  Therefore, to display the file on the standard output you
       type:
       cat file
       To concatenate two files and place the result on the third you type:
       cat file1 file2 > file3
       To concatenate two files and append them to a third you type:
       cat file1 file2 >> file3
       If no input file is given, or if a minus sign (-) is encountered as an argument, reads from the standard input file.  Output is buffered in
       1024-byte blocks unless the standard output is a terminal, in which case it is line buffered.  The utility supports the processing of 8-bit
       characters.

Options
       -b   Ignores blank lines and precedes each output line with its line number.

       -e   Displays a dollar sign ($) at the end of each output line.

       -n   Precedes all output lines (including blank lines) with line numbers.

       -s   Squeezes adjacent blank lines from output and single spaces output.

       -t   Displays non-printing characters (including tabs) in output.  In addition to those representations used with the -v  option,  all  tab
	    characters are displayed as ^I.

       -u   Unbuffers output.

       -v   Displays  non-printing  characters (excluding tabs and newline) as the ^x.	If the character is in the range octal 0177 to octal 0241,
	    it is displayed as M-x. The delete character (octal 0177) displays as ^?.  For example, is displayed as ^X.
