Hi I want to use awk to print avg and st deviation but it does not go into a file for column 1 only.

fileutil::magic::cfront - Generator core for compiler of magic(5) files SYNOPSIS
package require Tcl 8.4 package require fileutil::magic::cfront ?1.0? package require fileutil::magic::cgen ?1.0? package require fileutil::magic::rt ?1.0? package require struct::list package require fileutil ::fileutil::magic::cfront::compile path... ::fileutil::magic::cfront::procdef procname path... ::fileutil::magic::cfront::install path... _________________________________________________________________ DESCRIPTION
This package provides the frontend of a compiler of magic(5) files into recognizers based on the fileutil::magic::rt recognizer runtime package. For the generator backed used by this compiler see the package fileutil::magic::cgen. COMMANDS
::fileutil::magic::cfront::compile path... This command takes the paths of one or more files and directories and compiles all the files, and the files in all the directories into a single recognizer for all the file types specified in these files. All the files have to be in the format specified by magic(5). The result of the command is a Tcl script containing the generated recognizer. ::fileutil::magic::cfront::procdef procname path... This command behaves like ::fileutil::magic::cfront::compile with regard to the specified path arguments, then wraps the resulting recognizer script into a procedure named procname, puts code setting up the namespace of procname in front, and returns the result- ing script. ::fileutil::magic::cfront::install path... This command uses ::fileutil::magic::cfront::procdef to compile each of the paths into a recognizer procedure and installs the result in the current interpreter. The name of each new procedure is derived from the name of the file/directory used in its creation, with file/directory "FOO" caus- ing the creation of procedure ::fileutil::magic::/FOO::run. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category fileutil :: magic of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. SEE ALSO
