The below awk uses $3 and $4 in search as the min and max, then takes each $2 value in lookup and compares it. If the value in lookupfalls within the range in searchthen it prints the entire line in lookup/ICODE]. What I can't seem to figure out is how to print the matching $5 from search on that...

I am trying to update the below awk, kindly provided by @RavinderSingh13, to update each line of file1 with either Low or No Low based on matching $2 of file1 to a range in $2 and $3 of file2. If the $2 value in file1 matches the range in file2 then that line is Low, otherwise it is No Low in the... (3 Replies)
I use conditional operators alot in AWK to print rows from large text files based on values in a certain column. For example:
awk -F '\t' '{ if ($1 == "A" || $1 == "C" ) print $0}' OFS="\t" file1.txt > file2.txt
In this case every row is printed from file1 to file2 for which the column 1... (5 Replies)

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [ options ] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If one of the file names is the
standard input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Input fields are normally separated spaces or tabs; output fields by space. In this case, multiple separators count as one, and leading
separators are discarded.
The following options are recognized, with POSIX syntax.
-a n In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-v n Like -a, omitting output for paired lines.
-e s Replace empty output fields by string s.
-1 m
-2 m Join on the mth field of file1 or file2.
-jn m Archaic equivalent for -n m.
-ofields
Each output line comprises the designated fields. The comma-separated field designators are either 0, meaning the join field, or
have the form n.m, where n is a file number and m is a field number. Archaic usage allows separate arguments for field designators.
-tc Use character c as the only separator (tab character) on input and output. Every appearance of c in a line is significant.
EXAMPLES
sort /adm/users | join -t: -a 1 -e "" - bdays
Add birthdays to password information, leaving unknown birthdays empty. The layout of is given in users(6); bdays contains sorted
lines like
tr : ' ' </adm/users | sort -k 3 3 >temp
join -1 3 -2 3 -o 1.1,2.1 temp temp | awk '$1 < $2'
Print all pairs of users with identical userids.

With default field separation, the collating sequence is that of sort -b -ky,y; with -t, the sequence is that of sort -tx -ky,y.
One of the files must be randomly accessible.
