cat, read, nobs - catenate files


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


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.
