SYNOPSIS

       cat [-suv [-et]] [-B size] [file ...]

DESCRIPTION

       Cat  reads  each file in sequence and writes it on the standard output.
       Thus

              cat file

       prints the file and

              cat file1 file2 >file3

       concatenates the first two files and places the result on the third.

       If no file is given, or if the argument `-' is encountered,  cat  reads
       from the standard input.

       The cat command accepts the following options:

       -u     Ensures output to be unbuffered.

       -s     Causes  cat to be silent about files that cannot be opened, read
              problems and similar error conditions.

       -v     With this option given, non-printable  characters  are  detected
              and printed as `^n' for control characters and `M-n' for charac-
              ters with the high bit set.

       -t     If -v is present, this option causes tab and formfeed characters
              to be handled as control characters.

       -e     If  -v  is  present, this option causes end-of-line to be marked
              with `$'.

       The following option is an extension:

       -B size
              Causes input and output to be performed in size byte units.
