Top Forums Shell Programming and Scripting Egrep a number greater than in a column Post 302803347 by Don Cragun on Monday 6th of May 2013 12:41:05 PM

Sorry, but grep is not an option for this. The grep family of utilities doesn't do arithmetic (including numeric comparisons), it matches strings.

------------------------

I take it back. There is a way to do it, it is just messy (and you will need to re-engineer a different expression for each value you're trying to compare). What do you mean by field 2? In you example is field 2 supposed to be 12 or 19? Will you ever have negative numbers? For non-zero values, will there ever be a leading 0?

With grep you don't have $2 to specify the second field and once you have the second field you don't have >.

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).

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 SEE ALSO
