cat \- catenate and print
.SH SYNOPSIS
.B cat
[
.B \-u
]
file ...
.SH DESCRIPTION
.I Cat
reads each
.I file
in sequence
and writes it on the standard output.
Thus
.PP
.ti+15n
cat file
.PP
prints the file, and
.PP
.ti+15n
cat file1 file2 >file3
.PP
concatenates the first two files and places the result on the third.
.PP
If no input file is given,
or if the argument `\-' is encountered,
.I cat
reads from the standard
input file.
Output is buffered in 512-byte blocks unless the standard
output is a terminal or the
.B \-u
option is specified.
.SH "SEE ALSO"
pr(1), cp(1)
.SH BUGS
Beware of `cat a b >a' and `cat a b >b', which destroy
the input files before reading them.
