Awk?

Hi,

I am new to awk, so please bear with me! I have two files:

File1:
Code:
Low    High
14000    20000
25000    41000
60000    80000

File2:
Code:
Income    Name
12000    smith
15000    adam
22000    john
26000    denver

I want to loop through File1, and for each range (Low to High) extract the rows in File2. So my output file should look like

Desired output:
Code:
15000    adam
26000    denver

Using awk I can loop through File2, extract the Income for each row, but how do I see if the Income is within the range in File1? My code for looping:

Code:
awk '{ for (i = 1; i <= NR; i++) print $1 }' File2

Any help guidance would be appreciated!

thanks!

Join two files and extract relevant fields:
Code:
awk '
        NR == FNR {
                A[$2] = $1
                next
        }
        {
                for ( k in A )
                {
                        if ( A[k] >= $1 && A[k] <= $2 )
                                print A[k], k
                }
        }
' file2 file1

Code:
awk 'NR==FNR{l[++c]=$1;h[c]=$2;next} {for(i=1;i<=c;i++) if ($1>=l[i] && $1<=h[i]) print}' file1 file2

OR this small modification of Yoda's solution

Code:
$ awk '
       NR>1 && NR == FNR {
                A[$2] = $1
                next
        }
        {
                for ( k in A )
                {
                      if($1 >= A[k] && $1 <= k){ print ; break} 
                }
        }
' file1 file2

15000    adam
26000    denver
