cat

cat [options] [files]

Read (concatenate) one or more files and print them on standard output. Read standard input if no files are specified or if - is specified as one of the files; input ends with EOF. You can use the > operator to combine several files into a new file, or >> to append files to an existing file. When appending to an existing file, use Ctrl-D, the end-of-file symbol, to end the session.

Options
-A, --show-all	Same as -vET.
-b, --number-nonblank	Number all nonblank output lines, starting with 1.
-e	Same as -vE.
-E, --show-ends	Print $ at the end of each line.
-n, --number	Number all output lines, starting with 1.
-s, --squeeze-blank	Squeeze down multiple blank lines to one blank line.
-t	Same as -vT.
-T, --show-tabs	Print TAB characters as ^I.
-u	Ignored; retained for Unix compatibility.
-v, --show-nonprinting	Display control and nonprinting characters, with the exception of LINEFEED and TAB.
