NAME
cat - catenate and print
SYNOPSIS
cat [ -u ] file ...
DESCRIPTION
Cat reads each file in sequence and writes it on the standard output. Thus
- cat file
prints the file and
- cat file1 file2 >file3
concatenates the first two files and places the result on the third.
If no file is given, or if the argument `-' is encountered, cat reads from the standard input. Output is buffered in 512-byte blocks unless the standard output is a terminal or the -u option is present.
SEE ALSO
pr(1), cp(1)
BUGS
Beware of `cat a b >a' and `cat a b >b', which destroy input files before reading them.
