Within AWK, how do you display a field of NR? Here's my code:
I can change NR and print line #'s, but cannot get a field to print...the error comes at the segment
Your awk program (after unneeded quote removal) is:
Which after throwing away the strings from the print statement, leaves 4 expressions to be evaluated and printed: P1*.0000179, NR*60/431900, NR-10($1), and NR+70($1). The first two of these are valid expressions in awk; the last two are not. What were you expecting those expressions to do?
Without having a sample of your input file, an example of the output you expect to produce, and a description of what you're trying to do; there isn't any way that we can help correct your code.
Howdy.
I know this is most likely possible using sed or awk or grep, most likely a combination of them together, but how would one go about running a grep like command on a file where you only try to match your pattern to the second field in a line, space delimited?

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
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
