cat - concatenate and print files
cat [-benstuv] [file ...]
cat reads and prints the files in order they are given. If no files are given, standard input is processed. A lone dash represents standard input as well.
cat accepts the following options:
Number all the non blank lines, starting at 1.
Print a dollar sign ($) at the end of each lines. Implies -v.
Number all the lines, starting at 1.
The squeeze option. Sequential empty lines are squeezed into a single empty line.
Display tabs as ^I. Implies -v.
Display non-printable characters in a printable way. Characters in the range \000 - \037, with the exception of tabs and linefeeds, are printed as ^X, where X is the symbol \0100 higher. DEL is printed as ^?. Characters whose highest bit is set are printed as M-, followed by the representation of the character with the high bit stripped.
The working of cat is not influenced by any environment variables.
cat has no known bugs.
