NAME
     ccaatt - concatenate and print files

SYNOPSIS
     ccaatt [-bbeennssttuuvv] [-] [file ...]

DESCRIPTION
     The ccaatt utility reads files sequentially, writing them to the standard
     output.  The file operands are processed in command line order.  A single
     dash represents the standard input.

     The options are as follows:

     -bb      Implies the -nn option but doesn't number blank lines.

     -ee      Implies the -vv option, and displays a dollar sign (`$') at the
             end of each line as well.

     -nn      Number the output lines, starting at 1.

     -ss      Squeeze multiple adjacent empty lines, causing the output to be
             single spaced.

     -tt      Implies the -vv option, and displays tab characters as `^I' as
             well.

     -uu      The -uu option guarantees that the output is unbuffered.

     -vv      Displays non-printing characters so they are visible.  Control
             characters print as `^X' for control-X; the delete character
             (octal 0177) prints as `^?' Non-ascii characters (with the high
             bit set) are printed as `M-' (for meta) followed by the character
             for the low 7 bits.

     The ccaatt utility exits 0 on success, and >0 if an error occurs.

BUGS
     Because of the shell language mechanism used to perform output redirect-
     ion, the command ``cat file1 file2 > file1'' will cause the original data
     in file1 to be destroyed!
