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.
