+.TH CAT 1
+.SH NAME
+cat, read \- catenate files
+.SH SYNOPSIS
+.B cat
+[
+.I file ...
+]
+.br
+.B read
+[
+.B -m
+] [
+.B -n
+.I nline
+] [
+.I file ...
+]
+.SH DESCRIPTION
+.I Cat
+reads each
+.I file
+in sequence and writes it on the standard output.
+Thus
+.IP
+.L
+cat file
+.LP
+prints a file and
+.IP
+.L
+cat file1 file2 >file3
+.LP
+concatenates the first two files and places the result
+on the third.
+.PP
+If no
+.I file
+is given,
+.I cat 
+reads from the standard input.
+Output is buffered in blocks matching the input.
+.PP
+.I Read
+copies to standard output exactly one line from the named
+.IR file ,
+default standard input.
+It is useful in interactive
+.IR rc (1)
+scripts.
+.PP
+The
+.B -m
+flag causes it to continue reading and writing multiple lines until end of file;
+.B -n
+causes it to read no more than
+.I nline
+lines.
+.PP
+Read always executes a single
+.B 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.
+.SH SOURCE
+.B /sys/src/cmd/cat.c
+.br
+.B /sys/src/cmd/read.c
+.SH SEE ALSO
+.IR cp (1)
+.SH DIAGNOSTICS
+.I Read
+exits with status
+.B eof
+on end of file or, in the
+.B -n
+case, if it doesn't read
+.I nlines
+lines.
+.SH BUGS
+Beware of
+.L "cat a b >a"
+and
+.LR "cat a b >b" ,
+which
+destroy input files before reading them.
