cat(1)                                                     cat(1)



NAME
     cat - catenates and displays the contents of files

SYNOPSIS
     cat [-] [-e] [-s] [-t] [-u] [-v [file]...

ARGUMENTS
     -    Causes cat to read from the standard input.

     -e   Causes cat to display a dollar sign ($) before the
          newline character at the end of each line.  This option
          must be used in conjunction with the -v option; if it
          is not, cat ignores this option.

     file Specifies a file for cat to read.  If you do not use
          any file arguments, cat reads from the standard input.

     -s   Causes cat to be silent if a specified file does not
          exist.

     -t   Causes the tab character to be displayed as ^I and the
          form feed character to be displayed as ^L.  This option
          must be used in conjunction with the -v option; if it
          is not, cat ignores this option.

     -u   Causes cat to not buffer the output.

     -v   Causes cat to display nonprinting characters (with the
          exception of the form feed, newline, and tab
          characters) in a special way. If you use this option,
          cat displays control characters as ^X (CONTROL-X) and
          the delete character (octal 0177) as ^?.  Non-ASCII
          characters (characters whose high-order bit is set) are
          displayed as M-x, where x is the character specified by
          the seven low-order bits.

DESCRIPTION
     cat reads one or more files and writes the contents of each
     file to the standard output.

EXAMPLES
     This command displays the file named rose:

        cat rose

     This command catenates the contents of rose and wisteria and
     places the result in flowers:

        cat rose wisteria > flowers

WARNINGS
     This command causes the data in file1 to be lost:

        cat file1 file2 > file1

     Therefore, take care when using shell metacharacters to
     perform I/O redirection.
