I have the following two files:
file 1:
22
2
42
32
file 2:
1 10 valuea
11 20 valueb
21 30 valuec
31 40 valued
41 50 valuee
51 60 valuef
How can I make awk grab each value from file 1, match it up with file 2 based on whether it falls between the number range in columns 1 and 2 of file 2, and then print out column 3 from the matched column in file 2? The output would resemble the following:
valuec
valuea
valuee
valued
I tried using the following AWK command (based on what I found in this post: How to check value of a column lies between values of two columns in other file and print corresponding value from column in Unix? ), but it does not seem to be working correctly.
#!/bin/bash
awk 'FNR == NR { val[$1] = $1 }
FNR != NR { if (val[$1] >= $1 && val[$1] <= $2)
print $3
}' file1 file2
Also I did not include it in here for obvious reasons, but for the actual application of this script, file 1 would include around 7,000 entries while file 2 would include 68,000 entries
alternative awk
script
$ awk 'FNR == NR {a[$1]=$2; v[$1]=$3; next}
{for(k in a)
if(k+0<=$1 && $1+0<=a[k]) print v[k]}' file2 file1
valuec
valuea
valuee
valued
note that file2 is the first file. This will cover multiple range matches as well. +0
is to force for numerical comparison.
