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.
