Question move a variable value from csh to awk ...
Guys,

following is my issue:
------------------------
Code:
#!/bin/csh
#     specify a counter
@ k = 1
#     loop
while ($k < 3)
#     read all text file with a specific number less than 3 in the last column of a record
foreach file ( *.txt)
#     capture the line by passing the column number using $k and print the record
awk -v  k="$k" '{j = NF; if ($j == k) print $0}'   $file
end
#     increment the counter
@ k = `expr $k + 1`
end

---------------------
I have accomplished this using the following:
Code:
#!/bin/csh
awk '{j = NF; if ($j == 1) print $0}' *.txt 
awk '{j = NF; if ($j == 2) print $0}' *.txt 
awk '{j = NF; if ($j == 3) print $0}' *.txt

Appreciate the help.
Regards
Z

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
