Unix/Linux Scripts questions

# 8  
let me simplify it for you:
Code:
nawk '
    NF != 7 {
        printf("[%d] has invalid [%d] number of fields\n", FNR, NF)
    }
    $5 !~ /^[0-9]+$/ {
        printf("[%d] 5th field is invalid [%s]\n", FNR, $5)
}' ColCheckMe

Is it somewhat easier to parse/understand?
You should be able to see some of the familiar C/C++ concepts.

As far as helping others... I'm always willing to go 'extra mile' for someone who's willing to take a ride with me investing his/her/its own time investigating the "hints" given.
Having said that.... I'll close the 'brickbats' discussion.

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME
column -- columnate lists SYNOPSIS
column [-ntx] [-c columns] [-s sep] [file ...] DESCRIPTION
The column utility formats its input into multiple columns. Rows are filled before columns. Input is taken from file operands, or, by default, from the standard input. Empty lines are ignored. The options are as follows: -c Output is formatted for a display columns wide. -s Specify a set of characters to be used to delimit columns for the -t option. -t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the characters supplied using the -s option. Useful for pretty-printing displays. -x Fill columns before filling rows. -n By default, the column command will merge multiple adjacent delimiters into a single delimiter when using the -t option; this option disables that behavior. This option is a Debian GNU/Linux extension. ENVIRONMENT
The COLUMNS, LANG, LC_ALL and LC_CTYPE environment variables affect the execution of column as described in environ(7). EXIT STATUS
The column utility exits 0 on success, and >0 if an error occurs. EXAMPLES
(printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; printf "HH:MM/YEAR NAME " ; ls -l | sed 1d) | column -t SEE ALSO
colrm(1), ls(1), paste(1), sort(1) HISTORY
The column command appeared in 4.3BSD-Reno. BUGS
Input lines are limited to LINE_MAX (2048) bytes in length. BSD
July 29, 2004 BSD
