question: AWK and <
Unix Superusers,

I am trying to learn to use AWK and am relatively new to unix. I see an awk example in an AWK tutorial that is as follows:

Code:
awk -F: '{print $1}' < /etc/passwd |tail

can you please tell me what the < stands for in the above command?

Thanks!

George

DOTTY(1)                                                      General Commands Manual                                                     DOTTY(1)

NAME

       dotty - A Customizable Graph Editor

SYNOPSIS

       dotty [ -V ] [ file ]

DESCRIPTION

       dotty is a graph editor for the X Window System.  It may be run as a standalone editor, or as a front end for applications that use graphs.
       It can control multiple windows viewing different graphs.

       dotty is written on top of dot and lefty.  lefty is a general-purpose programmable editor for technical pictures.  It has  an  interpretive
       programming  language similar to AWK and C.  The user interface and graph editing operations of dotty are written as lefty functions.  Pro-
       grammer-defined graph operations may be loaded as well.  Graph layouts are made by dot, which runs as a separate process that  communicates
       with lefty through pipes.

USAGE

       The file name is optional. If present, the graph contained in that file is displayed in the dotty window.

OPTIONS

       -V     Prints the version.

SEE ALSO

       dot(1), lefty(1)
