cat - catenate and print
cat [ -u ] file ...
_C_a_t reads each _f_i_l_e in sequence and writes it on the stan- dard output. Thus
prints the file, and
cat file1 file2 >file3
concatenates the first two files and places the result on the third.
If no input file is given, or if the argument `-' is encoun- tered, _c_a_t reads from the standard input file. Output is buffered in 512-byte blocks unless the standard output is a terminal or the -u option is specified.
Beware of `cat a b >a' and `cat a b >b', which destroy the input files before reading them.
