cat[options] [files]
Read 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; end input with EOF.
You can use the > operator to combine several files into
a new file; use >> to append files to an existing file.
Print a $ to mark the end of each line. Must be used with -v.
Suppress messages about nonexistent files. (Note: In the BSD version, -s squeezes out extra blank lines.)
Print each tab as ^I and each form feed as ^L. Must be used with -v.
Print output as unbuffered (default is buffered in blocks or screen lines).
Display control characters and other nonprinting characters.
