cat

CAT(1)                      General Commands Manual                     CAT(1)



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.
