NAME

cat − concatenate files

SYNOPSIS

cat [ - ] [ file ...  ]

DESCRIPTION

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

cat file

prints the file to standard output, and the following

cat file1 file2 >file3

concatenates two files onto a third. 

If no file is given, or where − is given as an argument, cat reads from the standard input.  Output is buffered in blocks matching the input.

BUGS

Beware of cat a b >a and cat a b >b which destroy input files before reading them.
